Question 1:
For this question, you simply follow order of operations
P arenthesis
E xponents
M ultiplication
D ivision
A ddition
S ubtraction

Multiplication and Division along with addition and subtraction are of equal order and are done left to right.

-12 ÷ 3 × ( - 8 + (-4)^2 - 6) + 2 ------ Look at parenthesis first. Then there is an exponent in those parenthesis.

-12 ÷ 3 × ( -8 + 16 - 6) + 2 ------- Still simplify parenthesis.

-12 ÷ 3 × 2 + 2 ----- Now division
-4 × 2 + 2 ------- Now multiplication
-8 + 2 ------- And finally addition
-6

Question 2:
|-3| and -3
| | means absolute value. Absolute value is the distance a point is from zero on a number line to explain simply. A distance cannot be negative. We know that -3 is three points away from zero so the |-3| is 3. This is different from just -3 because it is the opposite sign.

lorasvet [3.4K]

Answer:

B) SAS

Step-by-step explanation:

Notice that there are two pairs of congruent sides, AC is congruent with ZX, and BC is congruent with YZ. Since there's one angle in each triangle that's congruent to each other, we can say B is the only true answer.

A certain game involves tossing 3 fair coins, and it pays .14 for 3 heads, .06 for 2 heads, and .01 for 1 head. The expected win
Romashka [77]

Answer:

Total expected amount = $0.04375

Step-by-step explanation:

We need to calculate probability of getting heads on every combination of coin tosses

HHH = 1/8 = 3 heads

HHT = 1/8 = 2 heads

HTH = 1/8 = 2 heads

HTT = 1/8 = 1 head

THH = 1/8 = 2 heads

THT = 1/8 = 1 head

TTH = 1/8 = 1 head

TTT = 1/8 = 0 head

So the probability of 3 heads is 1/8 and the amount is (1/8)* 0.14 = $0.0175

Probability of 2 heads is 3/8 and the amount is (3/8) * 0.06 = $0.0225

Probability of 1 head is 3/8 and amount is (3/8) * 0.01 = $0.00375

Total expected amount = 0.00375 + 0.0225 + 0.0175

Total expected amount = $0.04375

The Pythagorean theorem tells you the length of the diagonal is the square root of the sum of the squares of the side lengths:

diagonal = √(30^2 +22^2) = √1384 ≈ 37 . . . . feet
