At the bakery where you work, loaves of bread are supposed to weigh 1 pound, with a standard deviation of 0.13 pounds. You belie

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

H0 : μ = 1

H1 : μ > 1

Sample size, n = 20 ; xbar = 1.05; Standard deviation, s = 0.13

Test statistic;

t because sample size is < 30

(xbar - μ) ÷ (s/sqrt(n))

(1.05 - 1) ÷ (0.13 / sqrt(20))

0.05 ÷ 0.0290688

= 1.7200572

Using a p value calculator :

With alpha = 0.05 ; df = n - 1 = 20 - 1 = 19

P value = 0.05084

P value > alpha

We fail to reject H0

There is not sufficient evidence to support that the new personnel are producing loaves that are heavier than 1 pound

Find h. 11 in. h = [?] in in. 14 in. PLEASE OH PLEASE HELP ME IM DESPERATE

Sliva [168]

11^2 = h^2 + ( 14/2)^2

11^2 = h^2 + 7^2

121 = h^2 + 49

h^2 = 121 - 49

h^2 = 72

h = √72

if y represents total earnings in dollars and x represents hours worked, then which equation models the wages of someone who mak

Klio2033 [76]

Answer: $y=11.50x$

Step-by-step explanation:

1. You have the following information given in the problem above:

- y represents total earnings in dollars .

- x represents hours worked.

2. Keeping on mind that the expression must model the wages of someone who makes $11.50 in an hour, this amount of money per hour must multiply the hours worked, which is represented by x.

3. Therefore, you can write the following equation:

$y=11.50x$

Directions: Write each equation in slope intercept form (y = mx + b)

Gnesinka [82]

Answer:

Below.

I Hope it helps :)

Step-by-step explanation:

Slope intercept form :

y=mx+b

$2x + y = 1$

Slope intercept form :

$y = - 2x + 1$

Equation :

$x - 2y = 8$

Slope intercept form :

$- 2y = - x + 8$

$y = \frac{1}{2} x - 4$

$3x + 2y = 4$

Slope intercept form :

$2y = - 3x + 4 \\$

Divide through by 2

$y = - \frac{3}{2} x + 2$

Equation :

$x + 2y = - 4$

Slope intercept form :

$2y = - x - 4$

Divide through by 2

$y = - \frac{1}{2} x - 2$

$4x + y = 1$

Slope intercept form =

$y = - 4x + 1$

Equation :

$x + y = - 2$

Slope intercept form :

$y = - x - 2$
