Answer:

Step-by-step explanation:

In a study of the relationship between pet ownership and physical activity in older adults, 586 subjects reported that they owned a pet, while 1931 reported that they did not. Give a 98% confidence interval for the proportion of older adults in this population who are pet owners. Lower limit Incorrect: Your answer is incorrect. Upper limit

p ± z × (1 - p/n)

z = 98%

p = 586/1931

= 0.3034697048

n = 1931

Approximately = 0.3035

Confidence interval =

0.3035 + 2.326 × ( 1 - 0.3035/ 1931)

Answer:

x=8

Step-by-step explanation:

-2(8) would be -16 so -18 is still greater

Answer:

B

Step-by-step explanation:

all the others will have a value of more than -18. Only B makes sense.

Hope this helps! Have a great day

Answer:

78

Step-by-step explanation:

Arc GHJ is 81*2= 162 (the arc measure of an inscribed angle that does not cross the center of the circle is 2 times the measure of the angle

since arc GH is 84 and we need HJ, subtract 84 from 162=78

Answer:

m∡P = 40°

Step-by-step explanation:

15m + 17 + 4m - 10 + 7m - 9 = 180

26m - 2 = 180

26m = 182

m = 7

∡P = 7(7) - 9 = 49 - 9 = 40

Step-by-step explanation:

let's see....

3m × 5r = 15mr

15(m × r)

15mr.

Answer:

12.54

Step-by-step explanation:

When finding the mean, first you add all the numbers in the data:

9+14+14+9+20+6+8+19+17+13+9=138

And then you divide it by the following numbers in the set. In this data set, since there are 11 numbers, you would divide 138 by 11.

138\11=12.5454545

So the answer would be 12.54 if your rounding to the nearest hundred. If your rounding it by a whole number, it would be 13.

Answer:

The correct options are:

A, B, and E.

Step-by-step explanation:

A mathematical sentence (or a mathematical statement) is a sentence that can be true or false.

This is the only criteria we need to check, now let's analyze each option.

A: 4 - d = 12

This can be true or false, for example, if d = 0 the sentence is false because:

4 - 0 = 12

4 = 12 is false.

and if d = -8 the sentence is true, because:

4 - (-8) = 12

4 + 8 = 12

12 = 12

is true.

B: 4 - V > 2

This sentence can be true or false, same reasoning as before, we can find values of V such that this is true or false.

C: 3 + 2

Now, here we can't say if this is true or false, so this is not a mathematical sentence.

D: 59

Same as before, this is just a number.

E: 6 + a = 13

This can be true or false, depending on the value of a, then this is a mathematical sentence.

F: 12*x

Here we can not say if this is true or false, so this is not a mathematical sentence.

The correct options are:

A, B, and E.

Answer:

[tex]f(3) = -16[/tex]

Step-by-step explanation:

Given

[tex]f(x)= - 4x-4[/tex]

[tex]g(x)= 4x^2 + 4x + 2[/tex]

[tex]h(x)= 3x^2 - 3[/tex]

Required

[tex]f(3)[/tex]

We have:

[tex]f(x)= - 4x-4[/tex]

Substitute [tex]x = 3[/tex]

[tex]f(3) = -4 * 3 - 4[/tex]

[tex]f(3) = -12 - 4[/tex]

[tex]f(3) = -16[/tex]

Hence:

[tex]f(3) = -16[/tex]

Answer:

This graph shows a negative correlation

Answer:

Slope (m) = 2

Step-by-step explanation:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

consider 2 points - (20,20) and (30,40)

[tex]m = \frac{40-20}{30-20}[/tex]

[tex]m=\frac{20}{10}[/tex]

[tex]m=2\\[/tex]

∴ Slope (m) = 2

Answer:

Width = 9 yards, length = 42 yards

Step-by-step explanation:

Perimeter = 2xlength + 2xwidth. Let's call length L and width W. The question also states that L = 5W-3. Therefore, 102 = 2x (5W-3) + 2W. Then, 102 = 12W - 6. 108 = 12W, so W = 9 yards. Since L = 5W - 3, we get 45-3 = 42 yards.

Answer:

[tex]radius \: \: r = 5 \: cm \\ area = \pi {r}^{2} \\ = 3.14 \times (5) {}^{2} \\ = 78.5 \: {cm}^{2} [/tex]

Answer:

[tex]78.5cm^{2}[/tex]

Step-by-step explanation:

[tex]A=\pi r^{2}[/tex]

[tex]A=(\pi )(5)^{2}[/tex]

[tex]A=78.5[/tex]

so I guess rounding it to 79
