First we need to find the total area of the floor. Dividing the total area of floor by area of one package of tile will give us the number package of tiles that are needed to cover the floor.

The shape of floor is parallelogram with base 17.5 feet and height of 6 feet.
Area of parallelogram is the product of its base and height.

So,

Floor Area = 17.5 x 6 = 105 ft²

Area covered by 1 package of tile = 5 ft²

So, number of package of tiles that are needed = 105/5 = 21 package of tiles.

21 packages of tiles will be needed to fully tile the room.

A line of the equation has a slope of a/b, where a and b are integers.
ElenaW [278]

Answer:

Suppose a soccer goalie punted the ball in such a way as to kick the ball as far as possible down the field. The height of the b
Alexxx [7]

Answer:

57.98 yards

Step-by-step explanation:

When the ball is on the ground, the height is y=0, therefore:

y=-0.017x^2+0.98x+0.33

0=-0.017x^2+0.98x+0.33

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-0.98\pm\sqrt{0.98^2-4(-0.017)(0.33)}}{2(-0.017)}

x_1=57.98184919

x_2=-0.3347903693

Since distance cannot be negative, the ball landed 57.98 yards down the field from where the goalie kicked the ball.

What is the correlation coefficient for the model that predicts the list price of all homes using population as an explanatory v
denis23 [38]

Here, we are concerned about two variables from the above data set, namely, Condo or co-ops and the Unemployment rate. We use the CORREL function of Excel to calculate the correlation coefficient rate and it is = R = -0.01873.

A Weak (negative) correlation exists between the list price of condominiums and co-ops and the unemployment rate.

The correlation coefficient is a statistical measure of the strength of the connection between the relative actions of two variables. The values varied between -1.0 and 1. zero. A calculated wide variety greater than 1. zero or less than -1.zero means that there was an error within the correlation size.

The correlation coefficient is decided with the aid of dividing the covariance by way of the product of the 2 variables' popular deviations.

Correlation values above 0. eight are deemed to signify a strong tremendous linear courting between the variables. Values among zero and 0. three imply a vulnerable relationship or none.

Answer:

Find below correct question:

When she was 20, liz started saving $6,000 a year for retirement. her goal is to reach & 100,00 in savings by the time she’s 30. her account earns 8% interest per year, compounded annually. liz (will/ won’t) have saved $100,000 by age 30. she’ll (exceed/ fall short of) her goal by about ($10,081/ $13,081/ $14,011)

liz won’t have saved $100,000 by age 30. she’ll fall short of her goal by about  $13,081

Step-by-step explanation:

First and foremost we need to know the worth of Liz's retirement savings when she is 30 using excel fv formula as follows:

=fv(rate,nper,-pmt,pv)

rate is the interest earned per year which is 8%

nper is the duration of savings which is 10 years

pmt is the amount of yearly savings which is $6,000

pv is the present worth of total savings which is not known

=fv(8%,10,-6000,0)=$86,919.37  

Hence,Liz would be not be able to reach $100,000 at age 30.

Shortfall=$100,000-$86,919.37  =$ 13,080.63
