Answer:

50 Is a multiple of 10 because 5×10 = 50

Step-by-step explanation:

We want to fill in the gap in :

50 Is a(n) ________of 10 because 5×10 = 50

Recall that multiples of a number are obtained by multiplying the number by natural counting numbers.

In this case one multiple of 10 is 50.

The reason is that, we obtain 50 by multiplying 5 by 10 to get;

$5 \times 10 = 50$

Therefore the best complete is multiple.

Hello everybody. Can somebody please help me on this math question

Nutka1998 [239]

Answers:

<em>See below.</em>

Step-by-step explanations:

(A) This equation evaluates the cost to ship 100 lbs of wheat, which equals $130:

C(100) = 1.28(100) + 2

C(100) = 128 + 2

C(100) = 130

(B) The cost to ship 250 lbs of wheat would be $322:

C(250) = 1.28(250) + 2

C(250) = 320 + 2

C(250) = 322

C(x) = 50

C(x) = 48 + 2

C(x) = 1.28(37.5) + 2

Calculate the approximate probability that at least 2 children have been diagnosed with ASD among the 200 selected children.

mixas84 [53]

Answer:

The approximate probability that at least 2 children have been diagnosed with ASD among the 200 selected children is

0.01 or 1%.

Step-by-step explanation:

Number of selected children = 200

The probability of no child been diagnosed with ASD = P(None) = 198/200 = 0.99

Therefore, the probability of at least two children been diagnosed with ASD = 1 - 0.99 = 0.01.

This is the same as:

If 2 children have been diagnosed with ASD,

therefore, the approximate probability that at least 2 children have been diagnosed is:

2/200 = 0.01. This value is equal to 1%.

The above are summed up in:

The probability of at least one = 1/200 = 0.05

Therefore, the probability of at least two = 0.05 * 2 = 0.01

b) Generally, to find the probability of at least one event happening, we calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none). For two events happening, the sum of the probability of at least one in two places is deducted from 1 to get the probability of at least two.

-1+5x≥-16 I dont know how to solve

olasank [31]

Answer: $x \ge -3$

Explanation:

Follow PEMDAS in reverse to undo what's happening to x.

We first add 1 to both sides, then divide both sides by 5 to fully isolate x.

Refer to the steps below to see what I mean.

$-1 + 5x \ge -16\\\\5x \ge -16+1\\\\5x \ge -15\\\\x \ge -15/5\\\\x \ge -3\\\\$

The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.

The solution set for x is anything -3 or larger.

If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}

What solution do 2x2 - 13x + 21 = 0 and 2x2 + 9x - 56 = 0 have in common? Round your answer to the nearest tenth if necessary.

lys-0071 [83]

So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;

2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5

Hope this helps you. Any questions please ask.
