The value of x when y= 24 is -26

<h3>How to determine the value of x?</h3>

The given parameters are:

y varies directly with x, and y = 16 when x = -4.

This means that

y = kx

Where k is the constant of variation

So, we have:

16 = -4k

Divide by -4

k = -4

Substitute k = -4 in y = kx

y = -4x

When y = 24, we have:

24 = -4x

Divide by -4

x = -6

Hence, the value of x when y= 24 is -26

Solve the system of equations by multiplying and adding. Enter the solution as an ordered pair.
GREYUIT [131]

Answer:

(x, y) = (- 3, 4)

Step-by-step explanation:

Given the 2 equations

5x + 2y = - 7 → (1)

4x - y = - 16 → (2)

multiply all terms in (2) by 2

8x - 2y = - 32 → (3)

Add (1) and (3) term by term

(5x + 8x) + (2y - 2y) = (- 7 - 32)

13x = - 39 ( divide both sides by 13 )

x = - 3

Substitute x = - 3 into either (1) or (2) and solve for y

substituting in (1) gives

(5 × - 3) + 2y = - 7

- 15 + 2y = - 7 ( add 15 to both sides )

2y = 8 ( divide both sides by 2 )

y = 4

solution is (- 3, 4 )

hram777 [196]

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)
