Problem Statement

We are asked to find the critical t-value for a confidence level of 80% and sample size of 17.

Method

To solve this, we simply need to do two things:

1. Calculate the degrees of freedom:

$undefined$

you burn 10 calories each minute you jog.What integer represents the change in your calories after you jog for 20 mins

Hoochie [10]

The total calories burnt in 20 minutes are 200

Step-by-step explanation:

We have to do simple multiplication to find the number of calories burnt.

Given

Number of calories burnt in one minute = c = 10

Time = t = 20 min

So the total number of calories burnt in 20 minutes will be:

$C_t = c * t\\= 10 * 20\\=200\ calories$

Hence,

The total calories burnt in 20 minutes are 200

Solve for y. x + y + z = 4 4x - y - z = 1 x + z = 2

UNO [17]

Answer:

y=2

Step-by-step explanation:

note: it only says to figure out y

x+y+z=4

x+z+y=4

2+y=4 (since x+z=2)

y=4-2

y=2

for the function y = 15 - 6x, suppose the domain is only values of x from 10 to 20. What is the Range of the function?

emmainna [20.7K]

Y=-6(10)+15
y=-60+15
y=-45

y=-120+15
y=-105

range equals -105 to 45

On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, negative 3) and point B is at (negative 4, 9).

zimovet [89]

Answer: (0,1)

Step-by-step explanation:

If $(x_1, y_1)$ and $(x_2, y_2)$ are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.

Then , the coordinates of (x,y) is given by :-

$x=\dfrac{nx_1+mx_2}{m+n}$

$y=\dfrac{ny_1+my_2}{m+n}$

Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).

Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :

$x=\dfrac{2(2)+1(-4)}{1+2}=0$

$y=\dfrac{2(-3)+1(9)}{1+2=1}$

Hence, the x- and y- coordinates of point E = (0,1)
