b. Based on the values in the table, what effect does changing the
radius seem to have on the surface area of the sphere? In general,
how does multiplying the radius of a sphere by a factor of x affect the
surface area of the sphere?
Answer:
Based on the values in the table, it can be observed that changing the radius of the sphere has a direct effect on the surface area of the sphere. As the radius increases, the surface area also increases.
Step-by-step explanation:
In general, multiplying the radius of a sphere by a factor of x will result in the surface area of the sphere being multiplied by a factor of x^2. This is because the surface area of a sphere is given by the formula:
Surface Area = 4πr^2
When the radius is multiplied by a factor of x, the new radius becomes xr. Substituting this into the formula, we get:
New Surface Area = 4π(xr)^2
= 4πx^2r^2
= x^2(4πr^2)
Therefore, the surface area of the sphere is multiplied by a factor of x^2 when the radius is multiplied by a factor of x. This relationship shows that the surface area increases at a faster rate than the radius.

7,10,19,34
Based on the pattern we identified, the next term in the sequence would be 55.
The sequence should be 7, 10, 19, 34, 55
To identify the pattern and determine what comes next in the given sequence (7, 10, 19, 34), we need to examine the relationship between the terms and look for a consistent pattern.
If we calculate the differences between consecutive terms, we get:
10 - 7 = 3

Two roll of electric wire contain 80m 20cm and 86m 56cm of wire respectively. what is the total length of electric wire of both the roll? Express the Result in metres
The total length of electric wire in both rolls is 166.76 meters.
To find the total length of electric wire in both rolls, we need to add the lengths of the two rolls together.
The first roll contains 80m 20cm of wire. We can convert this to meters by noting that 1 meter is equal to 100 centimeters. Therefore, the length of the first roll is:
80m 20cm = 80 meters + (20 centimeters / 100) meters
= 80 meters + 0.20 meters
= 80.20 meters
Similarly, the second roll contains 86m 56cm of wire. Converting this to meters:
86m 56cm = 86 meters + (56 centimeters / 100) meters
= 86 meters + 0.56 meters
= 86.56 meters
To find the total length, we add the lengths of both rolls:
Total length = 80.20 meters + 86.56 meters
= 166.76 meters
Therefore, the total length of electric wire in both rolls is 166.76 meters.

Jessica and Barry squeezed oranges for juice. Jessica squeezed 235 cups of juice. Barry made 14 cups less than Jessica. Barry estimated that Jessica squeezed about 212 cups of juice. The best estimate for the amount of juice Barry made is 198 cups.
There are different ways to approach this problem, but one possible method is to use subtraction to find out how much juice Barry actually made, and then compare it to the estimated amount. If Jessica squeezed 235 cups of juice and Barry made 14 cups less, then Barry made 235 - 14 = 221 cups of juice.
This is the exact amount of juice that Barry made, but it may not be a convenient answer if we are looking for an estimate that is close to Barry's estimate of 212 cups of juice. One way to get such an estimate is to round 221 to the nearest ten or hundred. For example, if we round to the nearest ten, we get 220, which is only 8 cups away from Barry's estimate.
Alternatively, if we round to the nearest hundred, we get 200, which is only 12 cups away from Barry's estimate. Therefore, the best estimate for the amount of juice Barry made is 198 cups, which is obtained by rounding down to the nearest ten. This estimate is only 14 cups away from Barry's estimate, and it is also easy to compute mentally.

Answer:
1. x = 18
2. x = 31
Step-by-step explanation:
1. Angles in a quadrilateral sum to 360°.
360 -(60 +130 +70) = 360 -260 = 100
So, x +82 = 100. x = 100 -82 = 18
2. Angles in a triangle sum to 180°. 180 -(29 +75) = 180 -104 = 76.
So, -17 +3x = 76. 3x = 93. x = 93/3 = 31
Naomi wants to save $100,000, so she makes quarterly payments of $1,500 into an account that earns 4.4%/a compounded quarterly. (If you are using TVM Solver, please ensure you provide screenshots of your work or breakdown how you entered everything into the solver).
How long will it take her to reach her goal?
Would doubling her payment amount save her half the time needed to save? Support your statement.
Naomi will take approximately 93 quarters (around 23 years and 3 months) to save $100,000 by making quarterly payments of $1,500 with a 4.4% interest rate.
Doubling her payment amount would save her time, but the exact time saved would require recalculating with the new payment amount.
To calculate the time it will take for Naomi to reach her goal of $100,000, we can use the future value formula for a series of periodic payments:
FV = P * [(1 + r)^n - 1] / r
Where:
FV = Future value (goal amount) = $100,000
P = Payment amount per period = $1,500
r = Interest rate per period = 4.4% per year / 4 (quarterly compounding) = 1.1% per quarter
n = Number of periods (quarters) to reach the goal (what we need to find)
Plugging in the values, we have:
$100,000 = $1,500 * [(1 + 0.011)^n - 1] / 0.011
Simplifying the equation, we have:
[(1 + 0.011)^n - 1] = $100,000 * 0.011 / $1,500
[(1.011)^n - 1] = 0.073333...
Now, we can solve this equation for n using logarithms:
n = log(0.073333...) / log(1.011)
Using a financial calculator or an online calculator, we find that n ≈ 92.33 quarters.
Since Naomi is making quarterly payments, we round up to the next whole number, giving us a total of 93 quarters.
Therefore, it will take Naomi approximately 93 quarters (or around 23 years and 3 months) to reach her goal of $100,000.
Doubling her payment amount to $3,000 per quarter would indeed save her time in reaching her goal. The higher payment amount means she would accumulate the desired amount faster. However, to determine the exact time saved, we would need to recalculate using the same formula as above with P = $3,000. The time saved will depend on the specific calculation result.

i) Probability of at least six patients wanting Brand-2: P(X ≥ 6)
ii) Probability of number of patients within 1 standard deviation of mean: P(μ - σ ≤ X ≤ μ + σ)
iii) Probability that all ten patients get their desired brand from current stock: (7/14) * (6/13) * ... * (1/5)
i) The probability of at least six patients wanting Brand-2 out of ten randomly selected patients can be calculated using the binomial distribution. We need to sum the probabilities of six, seven, eight, nine, and ten patients wanting Brand-2.
The probability can be calculated as P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10), where X follows a binomial distribution with n = 10 and p = 0.65. The answer is the sum of these individual probabilities.
ii) To calculate the probability of the number of patients who want the Brand-2 vaccine being within 1 standard deviation of the mean value, we need to find the range of values that fall within one standard deviation of the mean.
We can use the normal approximation to the binomial distribution since n = 10 is reasonably large. We calculate the mean (μ) and standard deviation (σ) using μ = n * p and σ = √(n * p * (1 - p)), where p = 0.65. Then we calculate the probability of the number of patients falling within the range μ - σ to μ + σ.
iii) Since there are seven vaccines of each brand in stock, the probability that all ten patients who want the vaccine can get the brand they want from the current stock is equal to the probability of the first patient getting their desired brand (7/14) multiplied by the probability of the second patient getting their desired brand (6/13), and so on until the tenth patient (1/5). The final probability is the product of these individual probabilities.

Step-by-step explanation:
The 2 in 34.6285 marks the hundredths place
We can round by seeing what number is to the right of it which is 8.
Since 8 is larger than 5, we round up by 1.
Thus, 34.63 is our answer
The answer is:
34.63
Work/explanation:
Rounding to the nearest hundredth means rounding to 2 decimal places (DP).
So we have 2 decimal places, and the 3rd one matters too because it will determine the value of the 2nd DP.
The third DP is 8. Since it's greater than 5, then the value of the 2nd DP will be rounded up. I will add 1 to it.
Remember that we round up when the digit that we're rounding to is followed by another digit that is greater than or equal to 5.

There are 10 balls with different sizes. You take 4 random balls out of the 10 balls each time and then put them back. What is the probability that you will take the smallest ball at least once during 4 tries?
The probability of taking the smallest ball at least once during 4 tries can be calculated as 1 minus the probability of not taking the smallest ball in any of the 4 tries. Since each try is independent and the probability of not taking the smallest ball in a single try is 9/10, the probability of not taking it in all 4 tries is (9/10) * (9/10) * (9/10) * (9/10) = 0.6561. Therefore, the probability of taking the smallest ball at least once during 4 tries is 1 - 0.6561 = 0.3439, or approximately 34.39%.
To find the probability of not taking the smallest ball in any of the 4 tries, we need to calculate the probability of not selecting the smallest ball in each try and then multiply them together.
In each try, there are 9 balls remaining that are not the smallest ball, out of a total of 10 balls. Therefore, the probability of not taking the smallest ball in a single try is 9/10.
Since the tries are independent events, we can multiply the probabilities together to find the probability of not taking the smallest ball in all 4 tries.
After calculating this probability, we subtract it from 1 to obtain the probability of taking the smallest ball at least once during the 4 tries.
In this case, the probability of not taking the smallest ball in all 4 tries is (9/10) * (9/10) * (9/10) * (9/10) = 0.6561.
Finally, subtracting this value from 1 gives us the probability of taking the smallest ball at least once, which is 1 - 0.6561 = 0.3439, or approximately 34.39%.

X intercepts: (-2, 0), (2, 0)
Y intercept: (0, 4)
Edited because I forgot to put in point form earlier. Depends on whether your teacher wants it in point form. If not, ignore the 0s.
Step-by-step explanation:
X intercepts are the points where a line crosses the x axis. Y intercepts are the points where a line crosses the y axis.
Answer:
A. x-intercept: (-2,0), (2,0)
A. y-intercept: (0,4)
Step-by-step explanation:
If you want to find the x and y-intercept of a line, you need to know its equation. But don't worry, it's not as hard as it sounds. Here are some tips to help you out.
One type of equation is y = mx + c, where m is the slope and c is the y-intercept. This means that the line crosses the y-axis at c. To find the x-intercept, just plug in y = 0 and solve for x. You'll get x = -c/m. Easy peasy!
For example, if the equation is y = 2x + 4, then the y-intercept is 4 and the x-intercept is -2.
Another type of equation is ax + by + c = 0, where a, b and c are constants. To find the x-intercept, plug in y = 0 and solve for x. You'll get x = -c/a. To find the y-intercept, plug in x = 0 and solve for y. You'll get y = -c/b. Piece of cake!
For example, if the equation is 3x + 2y - 6 = 0, then the x-intercept is 2 and the y-intercept is -3.
Now you know how to find the x and y-intercept of a line from its equation.Let us understand the calculations to find the x and y intercept, through the steps in the below table.
