Martin earned the following scores on his last five tests.
sdas [7]

Answer:

The mean of Martin's scores is 85.2

Step-by-step explanation:

In order to find the mean of a set of numbers, you will have to add up all of the numbers and divide the result by the total numbers in the set.

98 + 78 + 84 + 75 + 91 = 426

Since there are 5 numbers in total, we will do 426 divided by 5.

426 ÷ 5 = 85.2

So, the mean of Martin's scores is 85.2

There are 1,000 cans of cat food produced daily at a factory. in the meeting last week, the
BaLLatris [955]

Using the binomial distribution, it is found that the true statement related to the number of cans of cat food the company expects to be dented is given by:

B. The factory can expect to have an average of 50 cans dented in a day.

<h3>What is the binomial probability distribution?</h3>

It is the probability of exactly<u> x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

In this problem, we have that there are 1000 cans, each with a probability of 1/20 of being dented, hence:

n = 1000, p = 1/20 = 0.05.

The expected value is then given by:

E(X) = np = 1000 x 0.05 = 50.

Researching the problem on the internet, the correct option is given by:

B. The factory can expect to have an average of 50 cans dented in a day.

Which number line shows the solution to the inequality –2(3x – 1) &lt; 8? A. Number lines from minus five to five by increament
never [62]

Answer:

The correct option is B.

Step-by-step explanation:

The inequality is: -2(3x - 1) < 8.

Solve for <em>x</em> as follows:

-2(3x - 1) < 8

-6x + 2 < 8

-6x < 6

-x < 1

x > -1

The solution for <em>x</em> is in the interval (-1, ∞].

The number line will be:

B. Number lines from minus five by increment of one from left to right and each tick mark is labeled. Shaded part from open circle at minus one to infinity

What’s the x and y intercept of 8x+5y=-48
Anuta_ua [19.1K]

Step-by-step explanation:

8x + 5y =  - 48 \\  \\ at \: x = 0 \\  \\ 8 \times 0 + 5y =  - 48 \\  \\  \therefore \: 5y  = - 48 \\  \\  \therefore \: y  =  \frac{ - 48}{5}  \\  \\ \therefore \: y  - intercept =   - 9.6 \\  \\ at \: y = 0 \\  \\ 8 x + 5 \times 0 =  - 48 \\  \\  \therefore \:8x  = - 48 \\  \\  \therefore \: x  =  \frac{ - 48}{8}  \\  \\ \therefore \: x - intercept =   -6 \\  \\

Can someone help (8 grade math)
adoni [48]

Answer:

B) 110.92 u²

Step-by-step explanation:

to find the surface area, find the area of each side and add them together.

here are all 6 sides:

4.5 * 6.8

4.5 * 6.8

4.5 * 2.2

4.5 * 2.2

2.2 * 6.8

2.2 * 6.8

4.5 * 6.8 = 30.6

4.5 * 6.8 = 30.6

4.5 * 2.2 = 9.9

4.5 * 2.2 = 9.9

2.2 * 6.8 = 14.96

2.2 * 6.8 = 14.96

30.6 + 30.6 + 9.9 + 9.9 + 14.96 + 14.96

110.92
