Answer:

A weak negative correlation

Step-by-step explanation:

$correlation, r = \frac{∑(y-\alpha)(x-\beta }{\sqrt{∑(y-\alpha)^2∑(x-\beta )^2 } }$

where,

$\alpha = \frac{∑y}{n} \\\beta =\frac{∑x}{n} \\∑ = summation$

$\alpha = \frac{3230}{4} = 807.5\\\\\\\beta =\frac{46}{4} = 11.5$

$therefore,\\\\r= -0.12924$

This represents a weak negative correlation

Write an equation of the line that passes through (0, – 6) and is parallel to the line y = 3x – 8. An equation of the parallel l

Semenov [28]

Answer:

y = 3x - 6

Step-by-step explanation:

In order to make a line parallel to the given equation, you must change the y value. Since it has to pass through point (0, -6), the b value of the equation will be changed to -6. Therefore, the answer is y = 3x - 6.

As an incoming college freshman, Tina received a 10-year $9,900 Federal Direct

Ksju [112]

The amount charged on the loan which is the loan interest rate, increases as the time after the initial amount is credited into the account increases.

The interest on the Federal Direct Unsubsidized Loan after 4 years 6 months is $1,911.195

Reasons:

The given parameter are;

Loan amount, the principal, P = $9,900

Duration of the loan = 10 years

Loan interest rate, R = 4.29%

Required:

The amount of interest that will accrue while she is still in school and over the 6-months grace period for the freshman loan.

Solution:

Based on a similar question on an online source, we have;

Interest, I = P × R × T

Where;

T = The time = The time the freshman is in school + 6 months

Therefore, normally, we have;

T = 4 years + 6 months = 4.5 years

R = 4.29% = 0.0429

Therefore;

Interest, I = 9,900 × 0.0429 × 4.5 = 1911.195

The interest that will accrue while she is still in school and over the 6-months grace period for the loan, I = $1,911.195

There is 60% chance that it will rain today. If it rains, the probability of watching a movie is 0.5. But, if it does not rain t

agasfer [191]

Applying the given probabilities, it is found that there is a 0.42 = 42% probability of watching a movie today.

These following probabilities involve a movie being watched today:

0.5 of 0.6(if it rains today).

0.3 of 1 - 0.6 = 0.4(if it does not rain today).

Hence, adding them:

$p = 0.5(0.6) + 0.3(0.4) = 0.3 + 0.12 = 0.42$

0.42 = 42% probability of watching a movie today.
