Answer:

x = 19/4 and y = 15/8

Step-by-step explanation:

Given:

y = (-3/2)x + 9

2x + 4y = 17

Move y to one side:

2x + 4y = 17

y = 17/4 - x/2

Solve for x:

(-3/2)x + 9 = 17/4 - x/2

x = 19/4

Substitute x to solve for y:

y = (-3/2)(19/4) + 9

y = 15/8

2(19/4) + 4y = 17

y = 15/8

A number, n, is multiplied by - 5/8. The products is - 0.40 What is the value of n? It would also help if you would explain how
Kay [80]
I'm not sure if those numbers are negatives or thats just a hyphen but:

N(-5/8)=-0.40

Division is always the opposite of multiplication

-0.40/(-5/8)=0.64

N=0.64

Birthdays of hockey players: In Malcolm Gladwell’s book "Outliers" he shares the work of Canadian psychologist Roger Barnsley, w
alexgriva [62]

Answer:

The P-value is 0.009.

Step-by-step explanation:

We are given that after debating whether this set of hockey players can be viewed as a random sample of hockey players, they decide to run a hypothesis test anyway to practice finding the P‐value.

<em><u>We are given that the following hypothesis below;</u></em>

Null Hypothesis, H_0 : p = 0.25

Alternate Hypothesis, H_A : p > 0.25

Now, the test statistics that was used here for the above hypothesis would be;  

                       T.S.  =  \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }  ~ N(0,1)

Also, the test statistics given to us is 2.37.

<u></u>

<u>SO, the P-value of the test statistics is given by the following formula;</u>

             P-value = P(Z > 2.37) = 1 - P(Z \leq 2.37)

                           = 1 - 0.99111 = 0.00889 ≈ 0.009

<em>The above probability is calculated by looking at the value of x = 2.37 in the z table which has an area of 0.99111.</em>

Therefore, the required P-value is 0.009.

Annie's cafe borrows $6100 at 6% for 290 days. Find the total amount that must be repaid after 290 days. (Use a 365 day year.)
goldenfox [79]
If its 6% interest, then the answer would be $6,466. You would do this by multiplying 0.06 to 6100 and adding the product (366) to 6100.

What is the point-slope equation of the line with slope
Rainbow [258]

Answer:

y-5 = 3/2(x+3)

Step-by-step explanation:

The point slope form of the equation for a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y-5 = 3/2(x--3)

y-5 = 3/2(x+3)
