Doubling (2 times ) the quantity (indicates a group) of a number (x) decreaded by (-) 6 (6) is less than (<) negative 36 (-36

2 times (x-6)<-36
divide both sides by 2
x-6<-36
add 6 to both sides
x<-30

Myra is evaluating the expression –31. 7 4. 5x, when x = 2. 1. -31. 7 4. 5(2. 1) –27. 2(2. 1) –57. 12 What was Myra’s error? Myr
murzikaleks [220]

This is just an algebraic problem, the correct option is:

<em>"Myra should have multiplied 4.5 and 2.1 first."</em>

<h3>How to evaluate an expression?</h3>

Here we want to evaluate the expression:

-31.7 + 4.5*x

in x = 2.1

This just means that we need to replace x by 2.1 in the given equation.

Now, what Myra does is:

-31.7 + 4.5*2.1 = -27.2*2.1

So she took the sum between -31.7 and 4.5 first, this is her mistake, you only would do that if the expression was:

(-31.7 + 4.5)*2.1

But in our expression:

-31.7 + 4.5*2.1

The first thing you need to solve is the product in the second term, so we get:

-31.7 + 4.5*2.1 = -31.7 + 9.45 = -22.25

In a carnival game, there are six identical boxes, one of which contains a prize. A contestant wins the prize by selecting the b
myrzilka [38]

Answer:

D) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/6.

Step-by-step explanation:

The Number of boxes = 6

Box containing a prize = 1

Probability of success, p = box containing a price / number of boxes = 1 /6

Number of trials = 5

Probability of success on exactly 2 trials, r = 2

Hence,

P(r = 2) = nCr * p^r * (1-p)^(n-r)

n = 5 ; r = 2 ; p = 1/6

Using a binomial probability calculator :

P(r = 2) = 0.1608
