Answer:

the null hypothesis would be: p = 70%/0.7

The alternative hypothesis would be: p < 0.7

Step-by-step explanation:

The null hypothesis is most of the time always the default statement while the alternative hypothesis is tested against the null and is its opposite.

In this case study the null hypothesis would be: the proportion of men who own cats is 70%: p = 0.7

The alternative hypothesis would be: the proportion of men who own cats is smaller than 70% : p < 0.7

3486 x 12 which equals 41832 then You would move the decimal up from 3 spaces from the 2 from 41832 which would put the decimal between the 1 and 8

Slope = 2/5; passes through (-3,1)
nydimaria [60]
Presumably we're after the line with that slope through that point.  In general the line through (a,b) with slope m is 

y-b = m(x-a)

Here we have a=-3, b=1, m=\frac 2 5

y - 1 = \frac 2 5 (x--3)

y = \frac 2 5 x + \frac 6 5 + 1

y = \frac 2 5 x + \frac{11}{5}

Check: The slope is clearly  \frac 2 5
 so we check

y = \frac 2 5 (-3) +\frac{11}{5} = \frac 5 5 = 1 \quad\checkmark

Vedmedyk [2.9K]

Answer:

No

Step-by-step explanation:

No.

i = prt is correct; its result is the simple interest earned.  

If you want to solve for time, t, divide both sides by pr:

i/(pr) = t
