note that divoding a negative number and a positive number will give a negative number so.. -4.12

Use the z-distribution, we have that:

1.

The null hypothesis is of [tex]H_0: p = 0.84[/tex].

The alternative hypothesis is of [tex]H_1: p > 0.84[/tex].

2. It would mean that at most 84% of teenagers think highly of their mother, as we could not conclude that the proportion is more than 84%.

3. We are working with a right-tailed test, hence it means that there is a 0.0225 = 2.25% probability that at least 0.9 = 90% of teenagers think highly of their mother.

4. The p-value is of 0.0225, which is less than the significance level of 0.05, which means that we would reject the null hypothesis.

Item 1:

At the null hypothesis, we test if the proportion of teenagers that think highly of their mother is of 84%, hence:

[tex]H_0: p = 0.84[/tex]

At the alternative hypothesis, we test if this proportion is greater than 84%, that is:

[tex]H_1: p > 0.84[/tex]

Item 2:

It would mean that at most 84% of teenagers think highly of their mother, as we could not conclude that the proportion is more than 84%.

Item 3:

135/150 = 0.9.

We are working with a right-tailed test, hence it means that there is a 0.0225 = 2.25% probability that at least 0.9 = 90% of teenagers think highly of their mother.

Item 4:

The p-value is of 0.0225, which is less than the significance level of 0.05, which means that we would reject the null hypothesis.

The volume will be 9 times increased if she triples the dimension of the square. So, yes, he is right because 3 is 2 times in the formula.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Given

Clare sketches a rectangular prism with a height of 11 and a square base and labels the edges of the base 8.

The side of the square is 8.

The height of the prism is 11.

Volume = Area of square × height.

The volume of the original prism will be.

[tex]\rm V_1 = 8 * 8 * 11\\\\V_1 = 704[/tex]

If she triples the side of the square.

Then dimensions will be

The side of the square is 24.

The height of the prism is 11.

The volume of the modified prism will be.

[tex]\rm V_2 = 24 * 24* 11\\\\V_2 = 9*704\\\\V_2 = 9 \ Times \ of \ V_1[/tex]

Thus, the volume will be 9 times bigger. So, yes, he is right because 3 is 2 times in the formula.

There is only one answer

There is $6,370. 78 money is in the account after 4 years.

Given

Isabel deposits $6,000 into an account that earns 1. 5% interest compounded monthly.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

The amount after 4 years is calculate by following formula;

[tex]\rm V(t)= P(1+\dfrac{r}{n})^{nt}[/tex]

Where t = years since initial deposit n = number of times compounded per year r = annual interest rate (as a decimal) P = initial (principal) investment V(t) = value of investment after t years.

Substitute all the values in the formula;

[tex]\rm V(t)=6,000\times (1+\dfrac{0.015}{12})^{12\times 4}\\\\V(t)=6,370.78[/tex]

Hence, there is $6,370. 78 money is in the account after 4 years.

Step-by-step explanation:

area of trapezoid = 1/2 × (a+b) h

where a = long base

b = short base

h = height

given that, a = 8, b = 5, a of trapezoid = 104:

area of trapezoid = 1/2 × ( 8+5) h

104 = 13/2 h

104 * 2 = 13 h

13 h = 208

h = 208 / 13

h = 16.0 ft.

Answer:

She spends 111 minutes doing cardio workouts and 39 minutes doing weight training

Step-by-step explanation:

Call the time she spend on cardio workouts : a
And the time she spend on weight training : b

We have : a + b = 150
                 a - b = 72
Add them together, we get : a + b + (a-b) -> a+ b + a - b = 150 + 72 = 222
                                                                      = 2a
=> 2a = 222, and we have a = 111
=> b = 150 - 111 = 39

"An area that includes 9 smaller rectangles and is the intersection of 3 of the 12 columns and 3 of the 6 rows is shaded."

A is fits the perfect description for what you said in the last paragraph.

It is C because:

C is the other answer because it's an equivalent fraction to A.

1/4 x 3/3 = 3/12

Answer:

y < 2

Step-by-step explanation:

we can see that the area below y - 2, is shaded. as the line is dotted we shall use " < " sign. go two upwards from origin and that's why our value of y is 2.

The horizontal dotted line is located at y = 2 and the colored area is below that line, so the solution would be less than 2.

Answer: y < 2

The expression represents the total number of points Mona will earn if she catches x fish, y octopus, and z crabs is 30x + 80y - 15z.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given to us

30 points for fish

80 points for Octopus

-15 points for crab

As it is given in the problem that Mona catches x number of fishes, y number of octopuses, and z number of cabs. therefore,

Points earned through fishes [tex]=x \times 30 = 30 x[/tex]

Points earned through Octopus [tex]=y \times 80 = 80 y[/tex]

Points earned through crabs[tex]=z \times -15= -15 z[/tex]

Total points earned by Mona in the video game

= Points earned through fishes, octopus, and crabs

[tex]=30x + 80 y -15z[/tex]

Hence, the expression represents the total number of points Mona will earn if she catches x fish, y octopi, and z crabs is 30x + 80y - 15z.

Probabilities are used to determine the chances of events

The probability that at least one of them did not go to graduation is 0.173

The number of students in Grade 12 class is:

n = 100

The number of students that went to the graduation is

p = 91

The above means that:

q = 9 --- the number of students that did not attend the graduation

So, the probability that at least two students do not attend the graduation is:

Pr = P(None) + P(One)

So, we have:

[tex]Pr = 9/100 * 8/99 + 9/100 * 91/99 + 91/100 * 9/99[/tex]

Pr = 0.173

Hence, the probability that at least one of them did not go to graduation is 0.173
