75% of the tape diagram is shaded.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

The tape diagram.

Let us consider the whole tape as 1 and 100%.

It is  divided into four parts.

3 parts of 4 parts are shaded.

Three divided by four.

3/4=0.75

Now multiply 0.75 with 100.

0.75×100

75%

Hence, 75% is the shaded diagram percentage.

Answer:

(32,16)

Step-by-step explanation:

When you dilate a coordinate by a factor say a, the coordinate of the image are multiplied by this factor to get the coordinate of the pre-image. For example, if the coordinate of the image is (x,y) dilated by a factor of "a", the coordinate of the pre-image will be (ax, ay)

Given the coordinate (16, 8) the coordinate of the pre image of dilated by a factor of 2 is given as;

(2×16, 2×8) = (32, 16)

Hence the coordinates for the pre-image Q is (32,16)

It decreases from negative infinity to -2, then increases, so x=-2 is a rel. min.

It increases from x=-2 to x=2, then decreases to infinity, so x=2 is a rel. max.

I would say none

because each one equals to 24 students, when it says there are 24 students in each are class. so you would need to do 24 * 5 to get the amount of students.

Answer:

The second answer choice

Step-by-step explanation:

if you divided the total amount of people in all of the art classes by 5 you would get 24. Or you could think of it as multiplying by 5 on both sides which would give you "s" because it cancels out on the left side.

Answer:

57/60-52/60

Step-by-step explanation:

First you have to make the denominator the same to subtract. By find out what number they have in common. And the number was 60.  15x4=60  and 20x3=60. And whatever you do to the bottom you do for the top 19x3= 57. 13x4=52. So the form would be 57/60-52/60. Once you find the form then you subtract 57-52=5 and when you minus the denominator it stays the same. so the ANSWER would be 5/60.

Answer:

249.22

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that:

Sample Mean [tex]\overline x[/tex] = 82.25

The Standard deviation of the population [tex]\sigma[/tex] = 30.00

The Sample size = 100,000

The margin of error M.O.E = 0.186

At a 95% confidence interval level;

[tex]=\overline x - M.O.E < \mu < \overline x + M.O.E[/tex]

= 82.25 - 0.186 < [tex]\mu[/tex] < 82.25 +  0.186

= 82.064 < [tex]\mu[/tex] < 82.436

= (82.064 , 82.436)

The 95% confidence interval of the population mean = (82.064 , 82.436)

Before we can determine the sampling error, we need to find the standard error of the mean.

The standard error of the mean is:

[tex]\mu_ {\bar x} = \mu = 82.25[/tex]

[tex]\sigma_{\bar x} = \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]\sigma_{\bar x} = \dfrac{30}{\sqrt{100000}}[/tex]

[tex]\sigma_{\bar x} = \dfrac{30}{316.23}[/tex]

[tex]\sigma_{\bar x} = 0.096[/tex]

At 95% confidence interval, the level of significance = 1 - 0.95 = 0.05

[tex]Z_{0.05/2} = Z_{0.025}[/tex] = 1.96

Now, the sampling error can be determined by using the formula:

[tex]=Z_{\alpha/2} \times \sigma _{\overline x}[/tex]

[tex]=Z_{0.025} \times \sigma _{\overline x}[/tex]

= 1.96 × 0.096

= 0.18816

Answer: b. Yes

Step-by-step explanation: Confidence Interval for a population proportion is calculated as:

p ± [tex]z\sqrt{\frac{p(1-p)}{n} }[/tex]

where

p is the sample proportion

n is sample size

z is z-score, in this case, as it is 95%, z-score=1.96

Calculating confidence interval:

[tex]p=\frac{152}{468}[/tex]

p = 0.3248

0.3248 ± [tex]1.96\sqrt{\frac{0.3248(0.6752)}{468} }[/tex]

0.3248 ± [tex]1.96\sqrt{0.000468}[/tex]

0.3248 ± 0.0425

Interval: 0.2823 < μ < 0.3673

The interval means we are 95% sure the true mean is between 0.2823 and 0.3673. As the campaign claims a proportion of no more than 0.32 of the voters wants to see Mayor Waffleskate defeated and the number is in the confidence interval, the claim is supported.

Answer:

60%

Step-by-step explanation:

A percent is technically just a fraction over 100.

To get that here, we simply divide the part (which is 1560 people) by the whole (which is 2600 people) and then multiply that by 100:

(1560 / 2600) * 100 = 0.6 * 100 = 60/100

Thus, we know that the percent is 60%.

Answer: 243

Step-by-step explanation:

It’s going up by the square roots of 3 so therefore the fourth term is 3 to the fourth power which is 243.

Answer:

Question 1) Is option C: 2. (Question 2) The correct answer is 1.09 for the K12 program. Question 3) Option A: The value of a motorcycle decreases by 12% each year. (Option C) Every year, the number of online subscribers to a service is 4 times what it was the previous year.

The ratio of outputs for any two inputs that are one value apart is 4 thus option (A) is correct. The ratio of outputs for any two inputs that are two values apart is 1/8. The situation in option (3) represents the exponential function.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given table,

The ratio of outputs for any two inputs that are one value apart = (-1/2)/(-1/8) = 4

The ratio of outputs for any two inputs that are two values apart = (-1/8)/(-1) = 1/8

Every year, the number of online subscribers to a service is 4 times what it was the previous year's exponential function with a 4^x exponent.

Hence "The ratio of outputs for any two inputs that are one value apart is 4. The ratio of outputs for any two inputs that are two values apart is 1/8 and the third statement shows exponential function".

Answer:

[tex]A^{-1} = \frac{1}{66} \left[\begin{array}{cc}-2&-5\\6&-18\end{array}\right][/tex]

Step-by-step explanation:

Given

[tex]A = \left[\begin{array}{cc}-18&5\\-6&-2\end{array}\right][/tex]

Required

Determine the inverse

A matric is of the form:

[tex]A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]

First, we need to calculate the determinant (D)

[tex]D = a * d - b * c[/tex]

By comparison, we have:

[tex]D = (-18 * -2) - (5 * -6)[/tex]

[tex]D = (36) - (-30)[/tex]

[tex]D = 36 +30[/tex]

[tex]D = 66[/tex]

The inverse is then represented as:

[tex]A^{-1} = \frac{1}{D} \left[\begin{array}{cc}d&-b\\-c&a\end{array}\right][/tex]

This gives:

[tex]A^{-1} = \frac{1}{66} \left[\begin{array}{cc}-2&-5\\6&-18\end{array}\right][/tex]
