Answer 1

I am pretty sure it’s 120%

Answer 2

Answer:

112%

Step-by-step explanation:

percentage change value formula

c2 = X2 - X 1 X 100

X1 1

WHERE,

C2 = RELATIVE VALUE

X2 = FINAL VALUE ( TODAY'S VALUE) = 32,860

X1 = INITIAL VALUE (1992 VALUE) = 15,500

PERCENTAGE CHANGE = 100

C2 = 32860 - 15500 X 100

15500 1

= 17, 360 X 100

15,500 = 1.12 X 100 = 112%.

Answers

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.

Lily exercises for a total of 150 minutes each week. She does weight training and cardio workouts. She spends more time doing cardio workouts. The difference between the time she spends on cardio workouts and the time she spends weight training is 72 minutes. How much time does Lily spend on each type of activity?

Answers

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

Find the slope of the line that contains (3,-2) and (4,3).

Answers

Answer:

m = 5

Step-by-step explanation:

Recall that "slope" = rise/run.

Moving from the first point to the second, we see a 'run' of 1 and a 'rise' of 5. Thus, the slope of the line containing these two points is

m = rise/run = 5/1, or m = 5

A businessman bought a personal computer for $10,768. Calculate the selling price of the personal computer if he made a profit of 12 percentage

Answers

Answer:

$12,060

Step-by-step explanation:

LET selling price be rep by x

since he made a profit of 12%, we then add to 100%

100% + 12% = 112%.

to find the selling price, we multiply cost price by 112%

112% x $10768 =

112 / 100 x $10,768

= 1.12 x $10,768 = 12,060

selling price = $12,060.

Step-by-step explanation:

Factinate claims that 84% of teenagers think highly of their mother. To investigate this claim, a school psychologist selects a random sample of 150 teenagers and finds that 135 think highly of their mother. Do these data provide convincing evidence that the true proportion of teens who think highly of their mother is greater than 0.84?
1. State appropriate hypotheses for performing a significance test. Be sure to define the parameter of interest The school psychologist performed the significance test and obtained a P-value of 0.0225.
2. Explain what it would mean for the null hypothesis to be true in this setting.
3. Interpret the P-value.
4. What conclusion would you make at the a = 0.05 level?

Answers

Use the z-distribution, we have that:

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.

How the p-value influences the decision?If the p-value is less than the significance level, the null hypothesis is rejected.If the p-value is more than the significance level, the null hypothesis is not rejected.

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.

GRADUATION In Grade 12 class of 100 students, 91 went to the Grade 12 graduation. If two people are chosen at random from the entire class, what is the probability that at least one of them did not go to graduation?

Answers

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

How to calculate the probability

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]

Evaluate

Pr = 0.173

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

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.

If she triples the side of the square.

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]
