A ball is thrown from the top row of seats in a stadium. The function h(t) = - 16t^2 + 80t + 96 gives the height, in feet, of th
Rudik [331]

Answer:

2s or 3s

Step-by-step explanation:

Given the function that models the height of the object as;

h(t) = - 16t^2 + 80t + 96

The ball reaches the ground when h = 0

Substitute

0 = - 16t^2 + 80t + 96

Divide through by -16

0 = t²-5t-6

t²-5t-6 = 0

t²-2t-3t+6 = 0

t(t-2)-3(t-2) = 0

(tt-2)(t-3) = 0

t - 2 = 0 and t-3 = 0

t = 2 and 3s

Hence it will take the ball 2s or 3s to reach the ground

storchak [24]

Answer:

Step-by-step explanation:

Given that researchers wondered whether the size of a​ person's brain was related to the​ individual's mental capacity

They selected a sample of 5 females and 5 males and measured their MRI counts and IQ scores.

The data is reported to the right. Complete parts ​(a) through ​(d) below.

We want scatter plot for IQ vs MRI in general.

So we group data into two columns X for MRI and Y for IQ and draw scatter plot

MRI IQ

 

816932 133

1001121 140

833868 132

856472 140

866662 130

1038436 139

1079550 141

924059 136

a) Scatter plot is attached as a file

b) correlation coefficient = Cov (x,y)/S_x S_y = 0.729889

B) Yes, MRI count and IQ are linearly related since the linear correlation coefficient is _____.0.729889 >0.5 and near to 1 than to 0

There is a positive moderate correlation between x and y (linear)
