A standard number cube is rolled. What is the probability of rolling a number less than or equal to 2?

Answer:

B

Step-by-step explanation:

<3 and <2 are on a straight line.a straight line is 180° .so <3 +<2=180.angles which add up to 180 ° are said to be supplement

The best statement in geometric proof that proves the theorem that vertical angles are equal [tex]\angle2 + \angle3 = 180^{\circ}[/tex]  because ∠2 and ∠3 are linear pair.

In the given proof, where the angles are labeled as ∠1, ∠2, ∠3, and ∠4,  demonstrate the equality of vertical angles by utilizing the concept of a linear pair:

Step 1: Given two lines intersect.

Step2:

Step 3:

Step 4:

By following this step-by-step geometric proof,  establish that the best statement to prove the theorem "Vertical angles are equal when two lines intersect" is the statement that defines vertical angles as "Vertical angles are formed by adjacent angles sharing a common side

I don't know what kind of calculator you have at your disposal, so I'll just give one way of computing the sample mean and standard deviation.

• To get the mean, add up all the data points and divide the total by the number of data:

[tex]\bar x = \displaystyle \sum_i \frac{x_i}n = \frac{1243+1264+\cdots+1275}9 \approx 1273.89 \\ \implies \boxed{\bar x \approx 1274}[/tex]

• To get the s.d. s, first compute the variance s² by adding up the squared difference between each of the data points and the sample mean, and divide the total by 1 less than the number of data:

[tex]s^2 = \displaystyle \sum_i \frac{\left(x_i-\bar x\right)^2}{n-1} = \frac{(1243-1274)^2+(1264-1274)^2+\cdots+(1275-1274)^2}8 \approx 1211.61[/tex]

The s.d. is the square root of the variance:

[tex]s^2 \approx 1211.61 \implies s \approx 34.8082 \implies \boxed{s\approx 35}[/tex]

The 90% confidence interval for the sample mean has upper and lower limits, respectively, of

[tex]\bar x \pm \dfrac{\left|Z_{\alpha/2}\right| s}{\sqrt n}[/tex]

(positive root for upper limit, negative root for lower limit)

where [tex]Z_{\alpha/2}[/tex] is the critical value for a (1 - α)×100% confidence level. By critical value, I mean

[tex]\mathrm{Pr}\left[ Z \le Z_c \right] = c[/tex]

where Z is a random variable following the standard normal distribution.

In this case, we have a 90% confidence level, so α = 0.1, and the critical value is [tex]Z_{0.05} \approx -1.64[/tex]. Then the confidence interval has upper limit

[tex]\bar x + \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 + \dfrac{1.64 \times 35}{\sqrt9} \approx 1292.97 \approx \boxed{1293}[/tex]

and lower limit

[tex]\bar x - \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 - \dfrac{1.64 \times 35}{\sqrt9} \approx 1254.8 \approx \boxed{1255}[/tex]

Answer:

  a.  see attached

  b.  $140

Step-by-step explanation:

The graph starts at y=65 when x=0 and increases by 25 for each increase of 1 in x. The attachment shows a graph of the equation.

__

Use x=3 in the equation.

  -25x +y = 65

  y = 65 +25x = 65 +25(3) = 140

A bracelet with 3 charms costs $140.

Answer:

2a + 4a-17 + 3a - 10 = 180

9a - 27 = 180

+27

9a. =207

÷9

a= 23

Check:

2x23=46

4x23 - 17 =75

3 x 23 - 10 =59

Angle on straight lines adds to 180 (46+75+59=180)

Answer:

D

Step-by-step explanation:

D)

13% of x is 2600

13% = 13/100

⇒ (13/100)x = 2600

⇒ 13/100 = 2600/x

FYI A) gives the same value of x as D)

Answer:

the period of this graph is [tex]\pi[/tex]

Step-by-step explanation:

The period is the length of the section that repeats.  So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x = [tex]\pi[/tex]

[tex]\pi[/tex] - 0 = [tex]\pi[/tex]

Therefore, the period of this graph is [tex]\pi[/tex]

Yes these side lengths can make a triangle

The triangle side length rule states that any 2 sides of a triangle are greater than the other side.

Let's use this rule to determine if these side lengths can make a triangle.

4+7=11 and 11 is greater than 10.

4+10=14 and 14 is greater than 7.

7+10=17 and 17 is greater than 4.

These side lengths can make a triangle.

G'(x) = 1 × g(x) × f(x) + g'(x) × x × f(x) + f'(x) × x × g(x)

G'(x) = g(x).f(x) + x.f'(x).g(x) + x.g'(x).f(x)

Thus ;

G'(3) = g(3).f(3) + 3f'(3).g(3) + 3g'(3).f(3)

G'(3) = 13×9 + 3×( - 11 )×13 + 3×( - 5 )×9

We need to convert the fraction into a whole number.

We have to solve 11 + 19 first:

30/3 = 10 so we need to increase the numerator:

Answer:

90

Step-by-step explanation:

First we take 11 to other side to give:

[tex]\frac{w}{3} = 19+11[/tex]

[tex]\frac{w}{3} = 30[/tex]

Now we escalate the 3 up to give

w = 30×3

w=90

To double check we can substitute our value of w into the original equation:

[tex]\frac{90}{3}-11 = 19[/tex]    ✅

1.  She made 91 shots.

2. She missed 30% of her shots, or 39 shots.

Step-by-step explanation:

1. 70% of 130 (or .7 times 130) is 91. The 70% is converted into decimals by moving the decimal 2 places to the left.
2. Out of 100%, 30% is the added percentage to make 100%. 30% of 130 (or .3 times 130) is 39. This can also be found my subtracting 91 from 130.
