Answer:

F.) H0:μ=4.55, Ha:μ≠4.55

A.) H0:μ=115, Ha:μ<115

H0:μ=69 , Ha:μ>69

Step-by-step explanation:

The null and alternative hypothesis are used in hypothesis testing.

Generally, both hypothesis negatives each other, with the alternative being the opposite of the null hypothesis.

1)the mean value of the population is 4.55 ; the researcher aims to test if the mean value differs from thus value, hence, Alternative ; μ ≠ 4.55

2.) The mean resting heart rate is said to be 115 ; this is the null claim. The reaesrch aims to test if heart rate slows down with age. Hence, the alternative will be to show that mean rate lesser Than 115 as claimed (μ < 115)

3.) Theean height of the population is claimed to be 69. Researcher aims to test if some people within the population have mean height abive this said height. (μ > 69)

Answer:

A) T = 24

b) 77.953

c)  t > 63.78 , t < 5.6

d) (7.029,27.5) and (40.97,55.23)

Step-by-step explanation:

Given

F(t) = t^2 e^-t/12, t ≥ 0

a) time for maximum concentration

  t = 24

b) determine maximum concentration at maximum time

F(24) = 77.953

c) determine when the concentration will dip below the level of 20.0

when t > 63.78 , t < 5.6

d) concentration function changes concavity  ( estimated from a graph )

(7.029,27.5) and (40.97,55.23)

attached below is the detailed solution

Answer:

-.095

Step-by-step explanation:

If he has 1,356 cards and each page he has holds 9 cards, we don't know how many pages he has, so that will be x

1,356/9x -----1,356 (# of cards) divided by 9 (cards each page holds) times x (# of pages)

Divide 9x by 9 to get x by itself -----9x/9=x

Then, what you do to one side you must do to another so divide 1,356 by 9 -----1,356/9=150.667

He needs 150 pages and has .667 left over.

Answer:

As the first number is 5, the second will be 7, and the third will be 9.

Step-by-step explanation:

First, let's break down what the information is telling us.

"three consecutive odd integers" means each number is 2 away from each other. So if we were to assign the variable x as the first number, the second would be x + 2 and the third would be x + 4

"sum of the smallest number and twice the middle number" refers to adding the first number and 2 times the second number. So we would write:

x + 2(x + 2)

"is 10 more than the largest number" connects the second part to an equation. This is saying the third number plus 10. So for this, we would write:

(x + 4) + 10

Now we join the information that we have written mathematically into an equation. Since we have an equation, we can solve for the first number, and hence the second and third numbers.

x + 2(x + 2) = (x + 4) + 10

x + 2x + 4 = x + 14

3x + 4 = x + 14

2x = 10

x = 5

As the first number is 5, the second will be 7, and the third will be 9.

The key idea for solving this question is to define a variable and connect it to an equation using the information provided. Try to think about how much information is needed and how many variables need to be defined.

Complete Table:

Result of Roll ------ Frequency ------- Experimental Probability

1 --------------------------- 22 ------------------- 0.176

2 --------------------------- 13 ------------------- 0.104

3 --------------------------- 18 ------------------- 0.144

4 --------------------------- 29 ------------------- 0.232

5 --------------------------- 37 ------------------- 0.296

6 --------------------------- 6 ------------------- 0.048

Step-by-step explanation:

Required: Complete the table

The table is divided into 3:

1. Result of Roll

2. Frequency (F)

3. Experimental Probability (P)

The relationship between (2) and (3) is:

[tex]P = \frac{F}{N}[/tex]

Where

N = Number of Rolls

N = 125

For Roll of Result = 2

Frequency = 13

The probability is calculated as thus:

[tex]P = \frac{13}{125}[/tex]

[tex]P = 0.104[/tex]

For Roll of Result = 3

Probability = 0.144

The Frequency is calculated as thus:

[tex]0.144 = \frac{F}{125}[/tex]

[tex]F = 0.144 * 125[/tex]

[tex]F = 18[/tex]

For Roll of Result = 4

Frequency = 29

The probability is calculated as thus:

[tex]P = \frac{29}{125}[/tex]

[tex]P = 0.232[/tex]

For Roll of Result = 5

Probability = 0.296

The Frequency is calculated as thus:

[tex]0.296 = \frac{F}{125}[/tex]

[tex]F = 0.296* 125[/tex]

[tex]F = 37[/tex]

For Roll of Result = 6

Frequency = 6

The probability is calculated as thus:

[tex]P = \frac{6}{125}[/tex]

[tex]P = 0.048[/tex]

For Roll of Result = 1.

To get the frequency; we subtract the sum of frequencies of roll of results 2 to 6 from the total number of rolls.

In other words:

Frequency of 1 = Total Rolls - (Frequency of 2 + Frequency of 3 + Frequency of 4 + Frequency of 5 + Frequency of 6)

Frequency of 1 = 125 - (13 + 18 + 29 + 37 +6)

Frequency of 1 = 125 - 103

Frequency of 1 = 22

The probability is calculated as thus:

[tex]P = \frac{F}{N}[/tex]

[tex]P = \frac{22}{125}[/tex]

[tex]P = 0.176[/tex]

Answer:

Zeina had 35 books and Ali had 5 books

Step-by-step explanation:

Equations

We know Zeina has seven times as many books as Ali. If we call

x = Number of books Ali has

Then Zeina has

7x = Number of books Zeina has

We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:

x + 15 = 7x - 15

Adding 15:

x + 15 +15 = 7x

Subtracting x:

15 +15 = 7x - x

Operating:

30 = 6x

Dividing by 6:

x = 30 / 6

x =5

7x = 35

Thus Zeina had 35 books and Ali had 5 books

Answer:

110

Step-by-step explanation:

Divide 176 by 8 to get 22 and then multiply 22 by 5 to get 110

Answer:

110

Step-by-step explanation:

176/8 is 22 so there are 22 slices per loaf.

To find the amount of slices in 5 loaves you multiply 22 and 5 to get 110.

Answer:

D.) n=6

Step-by-step explanation:

Answer:

slope of perpendicular line - m = -1/2

passing through (-2,3)

thus,

y-3 = -1/2 (x+2)

or y = -1/2x +2

An equation of the straight line perpendicular to [tex]\boldsymbol{y=2x-5}[/tex] which passes through [tex]\boldsymbol{(-2,3)}[/tex] is [tex]\boldsymbol{x+2y-4=0}[/tex]

An equation of a straight line is [tex]\boldsymbol{y=2x-5}[/tex]

Compare this equation with the form [tex]\boldsymbol{y=mx+b}[/tex] where [tex]\boldsymbol{m,b}[/tex] denote slope and [tex]\boldsymbol{y-}[/tex]intercept respectively.

So,

[tex]\boldsymbol{m=2}[/tex]

As the slopes of two perpendicular lines are negative reciprocals of each other, slope of a required line is equal to [tex]n=\frac{-1}{2}[/tex]

Take [tex](x_1,y_1)=(-2,3)[/tex]

Equation of the required line is [tex]\boldsymbol{y-y_1=n(x-x_1)}[/tex]

       [tex]y-3=\frac{-1}{2}(x+2)[/tex]

     [tex]2y-6=-1(x+2)[/tex]

[tex]x+2y-4=0[/tex]
