Calculating a correlation can help describe a relation between two quantitative variables' ___ and ___ . However, it is not suff

Fittoniya [83]

Answer:

direction

shape

scatter plots

shape and outliers

Step-by-step explanation:

Correlation is defined as the degree of correspondence between two variables.

When the values increase together, correlation is positive and when one value decreases as the other increases, correlation is negative .

Calculating a correlation can help describe a relation between two quantitative variables' direction and shape. However, it is not sufficient to use a correlation coefficient to describe two variables. The addition of scatter plots can provide other helpful details such as shape and outliers

In the summer of 2014, the average listing price for homes for sale in the Hollywood Hills was $2,663,995.

Wewaii [24]

Answer:

monthly payment: $15,903.61
interest: $2,368,664.10

Step-by-step explanation:

a) The loan amount is 90% of the price shown, so is ...

0.90 × $2,663,995 = $2,397,595.50

The monthly loan payment is given by the amortization formula:

A = P(r/12)/(1 -(1 +r/12)^(-12t))

A = $2,397,595.50(0.0525/12)/(1 -(1 +0.0525/12)^(-12·30))

A = $13,239.61

The monthly escrow payment will be 1/12 of the annual amount:

0.012 × $2,663,995 / 12 = $2664.00

So, the total monthly payment on the house will be ...

$13,239.61 +2664.00 = $15,903.61

b) The sum of monthly loan payments is ...

$13,239.61 × 360 = $4,766,259.60

so the interest on the $2,397,595.50 loan is ...

$4,766,259.60 -2,397,595.50 = $2,368,664.10

The height of a trapezoid can be expressed as x – 4, while the bases can be expressed as x + 4 and x + 9. if the area of the tra

AlexFokin [52]

Answer: 19 cm

Step-by-step explanation:

$A_{trapezoid}=\frac{b_{1}+b_{2}}{2}*h$

99 = $\frac{(x+4 + x+9}{2}*(x - 4)$

99 = $\frac{(2x + 13}{2}*(x - 4)$

198 = (2x + 13)(x - 4)

198 = 2x² + 5x - 52

0 = 2x² + 5x - 250

0 = 2x²- 20x + 25x - 250

0 = 2x(x - 10) + 25( x - 10)

0 = (2x + 25)(x - 10)

0 = 2x + 25 or 0 = x - 10

$-\frac{25}{2}$ = x or x = 10

Since length cannot be negative, $-\frac{25}{2}$ can be disregarded

Larger base: x + 9 = 10 + 9 = 19
