Fudgin [204]

Step-by-step explanation:

Here is the answer to this question,

His hypothesis would be:

Null hypothesis:

H0: μ(new) - μ(regular) = 0

Alternate hypothesis:

H1: μ(new) - μ(regular) > 0

The consumer is testing to know if his new detergent is better off in cleaning than the regular. The question says that higher scores after cleaning is used to signify which is better based on sufficiently clean garment. Since he is interested in knowing the mean scores of the differences, he should use the hypothesis I stated above.

Which of the following is the equation of a line parallel to the line y = 3x + 2,
earnstyle [38]

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 is in this form with slope m = 3

• Parallel lines have equal slopes, hence

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (10, 1) into the partial equation

1 = 30 + c ⇒ c = 1 - 30 = - 29

y = 3x - 29 ← in slope- intercept form

Subtract y from both sides

0 = 3x - y - 29 ( add 29 to both sides )

29 = 3x - y, thus

3x - y = 29 ← in standard form → B

A pencil and ruler cost 1.50 together. The ruler is 1.00 more. How much is pencil
Stella [2.4K]
Ok so the solution which greenrune will (hopefully) correct


total is 1.5
p+r=1.5
rule is 1 more than pencil
r=1+p
sub 1+p for r
p+1+p=1.5
2p+1=1.5
minus 1 from both sides
2p=0.5
divide both sides by 2
p=0.25

pencil=$0.25
