irakobra [83]

Answer:

A) H1: π < 0.10

Step-by-step explanation:

<u>One tailed test</u>:-

A test of any statistical hypothesis where the alternative hypothesis is one tailed ( right tailed or left tailed) is called a one - tailed test.

H1: μ < μ0 (left tailed test)

H1: μ > μ0 (right tailed test)

<u>two tailed test</u>:-

In a test of statistical hypothesis where the alternative hypothesis is two tailed , we assume that the null hypothesis

H0: μ = μ0 against the alternative hypothesis

H1: μ ≠ μ0

conclusion:-

given data It is claimed that in a bushel of peaches, fewer than 10% are defective so alternative hypothesis

H1: μ < 0.10

4(7 + 8m)=8(-1 + 4m)

mr Goodwill [35]

Answer:

There is no solution

Step-by-step explanation:

Let's use distributive property to solve this equation.

4(7+8m) = 8(-1+4m)

28+32m = -8+32m

-32m -32m

28= -8

There is no solution

А support wire 12 yards long is attached to the top of a utility pole 10

stira [4]

Answer:

6.6 yd

Step-by-step explanation:

$a^{2}$ + $b^{2}$ = $c^{2}$

$10^{2}$ + $b^{2}$ = $12^{2}$ Substitute a= 10 and c=12

100+ $b^{2}$ =144 Evaluate the Powers

$b^{2}$ =44 Subtract 100 on both sides.

b= $\sqrt{44}$ Square root both sides b>0 so you dont need ⊥

b=6.6 Use a calculator to evaluate.

Rewrite the function by completing the square.<br><br> f(x)=x^2-4x-26

Radda [10]

Answer:

$(x-2)^2-30$

Step-by-step explanation:

use the form $ax^2+bx+c$ to find the values of a, b, and c.

$a=1, b= -4, c = -26$

consider the vertex form of a parabola

$a(x+d)^2+e$

substitute the values of a and b into the formula $d=\frac{b}{2a}$

$d=\frac{4}{2(1)}$

simplify the right side.

find the value of e using the formula $e=c-\frac{b^2}{4a}$

$e=30$
