Answer:

Height After 8 weeks: 14 inches

Height after w weeks: y=0.5w+10

Step-by-step explanation:

The equation of the sunflower is y=0.5x+10.

Height after 8 weeks: y=0.5(8)+10

y=4+10

y=14

Height After 8 weeks: 14 inches

Height after w weeks: y=0.5w+10

5(x+2)=6x+3x-14 please solve

zavuch27 [327]

Answer:

5(x+2)=6x+3x−14

Step 1: Simplify both sides of the equation.

5(x+2)=6x+3x−14

(5)(x)+(5)(2)=6x+3x+−14(Distribute)

5x+10=6x+3x+−14

5x+10=(6x+3x)+(−14)(Combine Like Terms)

5x+10=9x+−14

5x+10=9x−14

Step 2: Subtract 9x from both sides.

5x+10−9x=9x−14−9x

−4x+10=−14

Step 3: Subtract 10 from both sides.

−4x+10−10=−14−10

−4x=−24

Step 4: Divide both sides by -4.

−4x

−4

−24

A/2(b+c)(d-e)^2 if a=-10, b=10, c=9, d=2, e=5

bearhunter [10]

Answer:

(-86)

Step-by-step explanation:

$\frac{a}{2} (b + c) {(d - e)}^{2} \\ \\ \frac{ - 10}{2} (10 + 9) {(2 - 5)}^{2} \\ - 50 - 45 {( - 3)}^{2} \\ - 50 - 45 (- 3)( - 3) \\ - 50 - 45 + 9 \\ - 95 + 9 = ( - 86)$

In a prior sample of U.S. adults, the Center for Disease Control (CDC), found that 8% of the people in this sample had pinworm b

kow [346]

Answer: a) 453 b) 1537

Step-by-step explanation:

As per given , we have

Margin of error : E= 0.025

Critical value for 95% confidence interval : $z_{\alpha/2}=1.96$

a) The prior estimate of population proportion : p=0.08

Required sample size :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.08(1-0.08)(\dfrac{1.96}{0.025})^2\\\\=452.386816\approx453$

The minimum sample size is 453 U.S. adults.

b) Since the prior estimate of population proportion is not available , so we take p= 0.5

Required sample size :-

$n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.96}{0.025})^2\\\\=1536.64\approx1537$

The minimum sample size is 1537 U.S. adults.
