An automobile manufacturer has given its car a 46.7 miles/gallon (MPG) rating. An independent testing firm has been contracted t
kondaur [170]

Answer: See explanation

Step-by-step explanation:

The null hypothesis H0: The null hypothesis states that there is no relationship between the two things that are being considered.

The alternative hypothesis is contradictory to H0 and it explains that there is a relationship between the two selected variables.

Based on the question, the null hypothesis H0 is that the rating of car is equal to 46.7 miles per gallon. μ = 46.7 MPG

The alternative hypothesis Ha is that the rating of the car is not equal to 46.7 Miles per gallon. μ ≠ 46.7 MPG

A)
andriy [413]

Answer:

a) 1/10

b) 110

Step-by-step explanation:

A) we start by getting the total number of rolls

That would be;

11 + 22 + 7 + 8 + 13 + 19 = 80

The frequency of getting a 4 is 8

The probability that the next roll will be a 4 is;

8/80 = 1/10

b) Firstly, we get the probability of getting a 2

We have this as:

22/80

So for 400 rolls, the number of 2’s will be;

22/80 * 400

= 22 * 5 = 110

If y varies directly as x, and y=6 when x=10, find x when y=18
mote1985 [20]
Y = kx as y and x are directly proportional
6 = 10k
k = 0.6
y = 0.6x
18 = 0.6x

Please help, i will mark brainlistest and give 20 points to anyone that helps me please!

Here are the coordinates:

(60, 105)

(62, 114)

(64, 124)

(66, 131)

(68, 139)

(70, 149)

(72, 158)

Step-by-step explanation: All you have to do is take the values for y and x and plug them in to get the coordinates that you need. After doing that, use the line that you've created and find a point that would fall directly above 75, or use the line of best fit (in a scatterplot, this is a line that fits most of the points).

Hope this helps!
