Answer:

26

Step-by-step explanation:

5 × 4 = 20 (rectangle)

8-5 = 3 (triangle)

3×4÷2 = 6

20+6 = 26

Answer:

x == 9

Step-by-step explanation:

Angle at the vertex is half the difference of those at the intercepted arcs;

35 = 1/2(120-15x+5)

35 * 2 = 120-15x-5

70 = 115 - 5x

70 - 115 = -5x

-45 = -5x

x = 45/5

x = 9

Hence the value of x is 9

Answer:

C 30 in

Answer:

9 meters

Step-by-step explanation:

To find the area of a rectangle you do length times width. To find a side length, or the width divide the area by the length. 99/11=9.

The width is 9 meters.

Answer:

B. parallelogram

Step-by-step explanation:

Given

See attachment for quadrilateral

Required

Select the type of quadrilateral

From the attached image, we have:

[tex]DE = FG[/tex] -- Opposite, Parallel and Equal

[tex]EF = GD[/tex] -- Opposite, Parallel and Equal

Since all 4 sides are not equal, then it is neither a square; nor a rhombus

Hence, the shape is a parallelogram

Answer:

The longest segment is approximately 19.13cm

Step-by-step explanation:

Given

[tex]l = 14cm[/tex]

[tex]w = 11cm[/tex]

[tex]h = 7cm[/tex]

Required

The length of the longest segment (d)

This is calculated using:

[tex]d = \sqrt{l^2 +w^2 + h^2[/tex]

So, we have:

[tex]d = \sqrt{14^2 +11^2 +7^2[/tex]

Using a calculator, the equation becomes

[tex]d = \sqrt{366[/tex]

Take square roots

[tex]d = 19.13cm[/tex]

Answer:

15mm

Step-by-step explanation

It says the perimeter is 120 pi, if pi is separate from 120, that would make 120 our radius 60. with 4 semicircles, divide 60 by 4 and boom, 15.

Answer:

Blue = YES

Red = NO

Green = YES

Step-by-step explanation:

Given the distribution of colors on a spinner :

Blue = 4 ; Red = 6 ; Green = 2

Number of spins = 24

Total = (4 + 6 + 2) = 12

Recall:

Probability, P = required outcome / Total possible outcomes

P(red) = 6 /12 = 1/2

P(blue) = 4 / 12 = 1/3

P(green) = 2 / 12 = 1/6

On 24 spins :

Possible number of red = 1/2 * 24 = 12

Possible number of green = 1/6 * 24 = 4

Possible number of blue = 1/3 * 24 = 8

Answer:

[tex]f(x)=\sqrt{x}+5[/tex]

Step-by-step explanation:

The parent function of the graph is clearly [tex]f(x)=\sqrt{x}[/tex]. However, at [tex]x=0[/tex], y is equal to 5. Therefore, the function translated up 5 units. Thus, the equation of the function is [tex]f(x)=\sqrt{x}+5[/tex].

Answer:

f(x) = 5 + √x

Step-by-step explanation:

x= 0 ==> y = 5

x= 25 ==> y = 10

this is sq root function, starting from y=5

so, f(x) = 5 + √x

Answer:

Step-by-step explanation:

First method information:

Sample size  n₁  = 549

x₁ ( people ignoring on-line harassment )  =  412

Proportion of people ignoring on-line harassment  p₁

p₁ =  412/549   p₁  =  0,75   q₁ =  1  -  p₁    q₁ = 0,25

Second method ( people chosen to respond)

Sample size   n₂  =  368

number of people responding   x₂  = 305

Proportion of people responding

p₂ =  305/ 368    p₂ =  0,83   then  q₂  =  0,17

a) Looking for differences in the approachs

Hypothesis test:

Null Hypothesis                     H₀         p₁  =  p₂

Alternative Hypothesis         Hₐ         p₁  ≠  p₂

Alternative Hypothesis indicates that the test is a two-tail test

Choosing a confidence interval  CI = 95 % then a significance level is       α = 5%     α  = 0,05  and from z-table we get  z(c) =  1.64

To calculate z(s)

z(s)  =  (  p₁  -  p₂ ) / EED

EED = √  p₁*q₁)/n₁  +  (p₂*q₂)n₂

EED = √  (0,75*0,25)/549   +  0,83*0,17)/368

EED = √ 3,41 *10⁻⁴   +  3,83*10⁻⁴

EED =   10⁻² *√ 3,41 + 3,83

EED =   10⁻² * 2,69

EED = 0,0269

z(s)  =  (  p₁  -  p₂ )/0,0269

z(s)  = -  0,08 / 0,0269

z(s)  =  - 2,97

p-value for z(s)  is  pvalue  = 0,0015

Comparing  z(s)  and  z(c)   modules

z(s) > z(c)  therefor z(s) is in the rejection region we have to reject H₀ and claim that there is a difference between the proportions

Answer:

a. 0.87

b. The margin of error is of 0.0124.

c. The 90% confidence interval for the population proportion of adults who think the future health of Social Security is a major economic concern is (0.8576, 0.8824).

d. The 95% confidence interval for this population proportion is (0.8553, 0.8847).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The confidence interval is:

[tex]\pi \pm M[/tex]

a. What is the point estimate of the population proportion of adults who think the future health of Social Security is a major economic concern.

The sample proportion, that is, 1740 out of n = 2000. So

[tex]\pi = \frac{1740}{2000} = 0.87[/tex]

0.87 is the point estimate.

b. At 90% confidence, what is the margin of error?

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

Then the margin of error is of:

[tex]M =  z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M =  1.645\sqrt{\frac{0.87*0.13}{2000}}[/tex]

[tex]M = 0.0124[/tex]

The margin of error is of 0.0124.

c. Develop a 90% confidence interval for the population proportion of adults who think the future health of Social Security is a major economic concern

[tex]\pi - M = 0.87 - 0.0124 = 0.8576[/tex]

[tex]\pi + M = 0.87 + 0.0124 = 0.8824[/tex]

The 90% confidence interval for the population proportion of adults who think the future health of Social Security is a major economic concern is (0.8576, 0.8824).

d.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

Then the margin of error is of:

[tex]M =  z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M =  1.96\sqrt{\frac{0.87*0.13}{2000}}[/tex]

[tex]M = 0.0147[/tex]

The confidence interval will be of:

[tex]\pi - M = 0.87 - 0.0147 = 0.8553[/tex]

[tex]\pi + M = 0.87 + 0.0147 = 0.8847[/tex]

The 95% confidence interval for this population proportion is (0.8553, 0.8847).

Hello! answer: 10

Step-by-step explanation:

Formula for area of squares: base × height

Formula for area of triangles: base × height ÷ 2

2 × 2 = 4

2 × 2 ÷ 2 = 2

4 × 2 ÷ 2 = 4

4 + 2 + 4 = 10 therefore the area is 10 hope that helps!
