The motion of an object was recorded by measuring the velocity of the object in meters per second at various times, as shown in

LekaFEV [45]

The regression equation that represents the relationship between velocity and time is:

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v), that is, time and velocity, are given as follows:

(0, 6.1), (2.1, 12.2), (5.3, 17.4), (8.2, 26.4), (10, 28.1), (12.1, 32.8).

Hence, inserting these points into a calculator, the equation is given by:

v = 2.19t + 6.7.

How do you answer <br> #5.

avanturin [10]

Umm this might be wrong, but i think you have do the inverse, which would make -4 positive, then add that to the 2, and then subtract that from 0.6 and then whatever you answer you get is equal to the variable z.

I need help with this word problem.

Rainbow [258]

Answer:

$3.22 per square feet

Step-by-step explanation:

To solve, I usually set up an equation:

$ 40.21 x

Then, use cross multiplication.

(12 1/2)x=40.21

Divide both sides by 12 1/2 or 12.5

x = 3.2168

Round to the hundredths place [because we're dealing with money]

$3.22

I hope this helps!

You order fifteen burritos to go from a Mexican restaurant, six with hot peppers and nine without. However, the restaurant forgo

Mrrafil [7]

Answer: 0.936

Step-by-step explanation:

Given : Total burritos ordered = 15

Number of burritos with hot peppers = 6

number of burritos without hot peppers =9

Then , the proportion of burritos with hot peppers= $p=\dfrac{6}{15}=0.4$

The number of burritos picked: n = 3

Then using binomial probability , the probability that at most two have hot peppers is given by:-

$P(x\leq2)=1-P(x=3)\\\\=1-^3C_3(0.4)^3(0.6)^0\\\\=1-(1)(0.4)^3=0.936$

Hence, the required probability = 0.936
