Answer:

The maximum value is 14.

Step-by-step explanation:

x has to be less than or equal to -2, but x is greater than or equal to -4(This means it can be -2, -3, or -4).

y is greater than or equal to 1, but it is less than or equal to 6(so it can be from 1, 2, 3, 4, 5, or 6.)

The maximum for x is -2 and the maximum for y is 6, so...

5 times -2 equals -10.

4 times 6 is 24.

-10 + 24 = 14.

This would be 16. When you subtract a negative number, it’s really like adding. Once this part is done, the expression would be 11.9+4.1. 11+4=15 and 0.9+0.1= 1. 15+1= 16.

What is 9 times 6 plus 7 minus 10?<br>​
ANEK [815]

Answer:

Your answer would be 51.

Step-by-step explanation:

Remember the mathematical sequence: PEMDAS

P=parenthesis

E= exponents

M=multiply

D=divide

A=add

S=subtract.

In this case, there are no parenthesis and there are no exponents, so we multiply. Then there is no divide in this equation, so we go straight to add and subtract. Remember to do all this in the order of PEMDAS.

Anon25 [30]

Answer:

(a) The probability that a randomly selected U.S. adult uses social media is 0.35.

(b) The probability that a randomly selected U.S. adult is aged 18–29 is 0.22.

(c) The probability that a randomly selected U.S. adult is 18–29 and a user of social media is 0.198.

Step-by-step explanation:

Denote the events as follows:

<em>X</em> = an US adult who does not uses social media.

<em>Y</em> = an US adult between the ages 18 and 29.

<em>Z</em> = an US adult between the ages 30 and above.

The information provided is:

P (X) = 0.35

P (Z) = 0.78

P (Y ∪ X') = 0.672

(a)

Compute the probability that a randomly selected U.S. adult uses social media as follows:

P (US adult uses social media (<em>X'</em><em>)</em>) = 1 - P (US adult so not use social media)

                                                   =1-P(X)\\=1-0.35\\=0.65

Thus, the probability that a randomly selected U.S. adult uses social media is 0.35.

(b)

Compute the probability that a randomly selected U.S. adult is aged 18–29 as follows:

P (Adults between 18 - 29 (<em>Y</em>)) = 1 - P (Adults 30 or above)

                                            =1-P(Z)\\=1-0.78\\=0.22

Thus, the probability that a randomly selected U.S. adult is aged 18–29 is 0.22.

(c)

Compute the probability that a randomly selected U.S. adult is 18–29 and a user of social media as follows:

P (Y ∩ X') = P (Y) + P (X') - P (Y ∪ X')

                =0.22+0.65-0.672\\=0.198

Thus, the probability that a randomly selected U.S. adult is 18–29 and a user of social media is 0.198.
