Im giving all I got on this please help A researcher found the average cost of one and two-bedroom apartments for different citi

es and graphed the data in a scatter plot, with cost's of one-bedroom apartments along the x-axis. the variables have a strong linear coorelation and the equation for the regression line is y=1.377x+137.763. based on the equation what should the researcher expect for the average cost of a two-bedroom apartment in a city wherre the average cost of a one-bedroom apartment is $724. A. about $1,083 B. about 1,135 C. about 1,272 D. about 1,062

Answer:

The percentage change in volume between cylinder A and cylinder B is 50%

Step-by-step explanation:

The volume of a cylinder is given by the formula

V= πr^2h

For cylinder A, where r=7 and h= 5, π=22/7

V= π * 7^2 * 5

V= π * 49 * 5

V= 769.69 cubic inch

For cylinder B

V= 490π

V= 1539.3804 cubic inch

The percentage change in volume between cylinder A and cylinder B

=[ (VA- VB)/VB] *100

=( 1539.3804 - 769.69) / 1539.3804

= 0.5000 * 100

= 50%

Use the compound interest formula A =​P(1 + ​r) t and the given information to solve for r.
Dmitry [639]

Answer:

Rounding to nearest hundredths gives us r=0.06.

So r is about 6%.

Step-by-step explanation:

So we are given:

A=P(1+r)^t

where

A=2300

P=1600

t=6.

A=P(1+r)^t

2300=1600(1+r)^6

Divide both sides by 1600:

\frac{2300}{1600}=(1+r)^6

Simplify:

\frac{23}{16}=(1+r)^6

Take the 6th root of both sides:

\sqrt[6]{\frac{23}{16}}=1+r

Subtract 1 on both sides:

\sqrt[6]{\frac{23}{16}}-1=r

So the exact solution is r=\sqrt[6]{\frac{23}{16}}-1

Most likely we are asked to round to a certain place value.

I'm going to put my value for r into my calculator.

r=0.062350864

Rounding to nearest hundredths gives us r=0.06.

Answer:

First question = 800 cm^3

Second question =120π

Step-by-step explanation:

The formula for volume is base x height x width.

The formula for area of cylinder is 2πrh+2πr^2 but it has no lid so

2πrh+πr^2.

What is the value of y in the triangle?
Readme [11.4K]

Answer:

• From trigonometric ratios:

{ \rm{ \sin( \theta) =  \frac{opposite}{hypotenuse}  }} \\

→ theta is 41°

→ opposite is y

→ hypotenuse is 26 ft

{ \tt{ \sin(41)  =  \frac{y}{26} }} \\  \\ { \tt{y = 26 \sin(41) }} \\  \\ { \boxed{ \tt{ \: y = 17.06 \:  \: ft}}}
