Answer:

k= 1 /15 x^3

Step-by-step explanation:

4/3 x 3/4 = 5k

5k= 1 /3 x^3

k= 1 /15 x^3

The required value of k in the given equation (4/3) × (3/4) = 5k is 1/5.

To find the value of k in the equation (4/3) × (3/4) = 5k, we need to simplify the left side of the equation and solve for k.

Multiplying the fractions on the left side:

(4/3) × (3/4) = 12/12 = 1

Now we have the equation 1 = 5k. To solve for k, we need to isolate it on one side of the equation.

Dividing both sides of the equation by 5:

1/5 = k

Hence, the value of k in the given equation is 1/5.

Complete question :

Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.

1. State the appropriate null and alternate hypotheses.

2. Compute the P-value.

Answer:

H0 : p = 0.5

H1 : p < 0.5

P value = 0.200454

Step-by-step explanation:

Given that :

Claim : Less than half internet users have posted photos or videos online.

Sample Proportion (p) = 865 / 1765 = 0.4900

The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.

The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;

P = 0.5

q = 1 - 0.5 = 0.5

The test statistic :

Z = p - p0 / sqrt(p0 * (q/n))

Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))

Z = - 0.01 / sqrt(0.5 *0.0002832)

Z = - 0.01 / sqrt(0.0001416)

Z = - 0.01 / 0.0119013

Z = - 0.8402443

The corresponding p value from the z statistic score at α = 0.01

= 0.200454

Cuz is a negative get in absolute value it always comes out positive

And it says below 0-9=-9

Answer:

Step-by-step explanation:

__________________________________________________________

B is the answer because,

if the negative sign is not inside the "brackets," then the number will still be negative.

__________________________________________________________

But, if the negative sign is connected to the number, or inside the "brackets," then it will always be positive.

__________________________________________________________

Here are the reasons why the rest are wrong.

__________________________________________________________

A is not correct because the outcome isn't negative, even though it's correct in mathematical instances.

__________________________________________________________

C is not correct because it is plainly not correct in itself.

__________________________________________________________

D is also not correct because it is not correct in the mathematical equations, even though it has a -9 as the equal, it's still wrong.

Answer:

A) -6n-6

Step-by-step explanation:

g(h(n)) means you are plugging in the value of h(n) into g(n) for n:

Given:

[tex]g(n)=-2n+4\\h(n)=3n+5[/tex]  

Therefore:

[tex]g(h(n))=-2(3n+5)+4\\g(h(n))=-6n-10+4\\g(h(n))=-6n-6\\[/tex]

This means your final answer is A) -6n-6

Subtract them like a regualr equation

[tex]\frac{15}{4}[/tex] - [tex]\frac{9}{4}[/tex] = [tex]\frac{6}{4}[/tex]

Convert  [tex]\frac{6}{4}[/tex] into a mixed number to get 1 [tex]\frac{1}{2}[/tex]

Answer:

275

Step-by-step explanation:

The best way to do this is to set it up in this equation:

4/100 = 11/x, in this, the 4 over 100 represents 4% out of 100%. The 11 over x represents the 11 students out of x amount of students. With this equation, you cross multiply to get 4x = 1100. Then you divide both sides by 4 to get x by itself. This will give you x=275

After solving the equation, the total number of students in the 7th grade is 275.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the data mentioned in the question,

Total number of students in the Environmental club = 11

Percentage of students from 7th grade = 4%

Let the total number of students in 7th grade be x

Then, the equation according to the statement will be,

4% of x = 11

So,
x = (11 × 100)/4

x = 275

Answer:

x < 25

3. 9.72

4. 14.3

5. 2.11

8. 5,105.16

10. 124.7

Step-by-step explanation:

AC = 46

AB + BC = AC

(4x + 7) + (3x + 4) = 46

4x + 7 + 3x + 4 = 46

(4x + 3x) + (7 + 4) = 46

7x + 11 = 46

7x = 46 - 11

7x = 35

x = 35/7

x = 5

AB = 4x + 7

AB = 4(5) + 7

AB = 20 + 7

AB = 27

BC = 3x + 4

BC = 3(5) + 4

BC = 15 + 4

BC = 19

Step-by-step explanation:

The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

Given the average cost to rent a car for a week is $276

And the standard deviation is $60

To determine the Z-score for a weekly rental of $423.00

Here,

ц = 276

σ = 60

X = 423

⇒ z-score = (X-ц )/σ

Substitute the values,

⇒ z-score =  (423 - 276)/60

⇒ z-score = 147/60

⇒ z-score = 2.45

Hence, the z-score for a weekly rental is 2.45.
