6 0

Answer:

D: 8

Step-by-step explanation:

7 + (2 + 6) ^2 ÷ 4 ⋅ (1/2)^4

According to PEMDAS

We to parentheses first

7 + (8)^ 2 ÷ 4 ⋅ (1/2)^4

Then we do exponents

7 + 64 ÷ 4 ⋅ (1/16)

The multiply and divide from left to right

7+64 ÷ 4 ⋅ (1/16)

7+16 ⋅ (1/16)

Then add and subtract from left to right

7+1

8

Answer:

<u><em>9 (3x+2)</em></u>

Step-by-step explanation:

<u>27x + 18 = 9 (3x+2)</u>

<em>By simplifying the Given expression you get 9 (3x+2) </em>

<em>and no matter how many times you simplify that expression you always get the expression you started with so in other word their equavalent to each other</em>

Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval. What
dezoksy [38]

Answer:

29.49% probability that a production time is between 9.7 and 12 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d, in which d is greater than c, is given by the following formula.

P(c \leq X \leq d) = \frac{d - c}{b-a}

Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval.

This means that a = 8, b = 15.8

What is the probability that a production time is between 9.7 and 12 minutes?

d = 12, c = 9.7.

So

P(c \leq X \leq d) = \frac{d - c}{b-a}

P(9.7 \leq X \leq 12) = \frac{12 - 9.7}{15.8 - 8} = 0.2949

29.49% probability that a production time is between 9.7 and 12 minutes

1.) The graph of g(x) = ax? opens downward and is narrower than the graph of f(x) = x? Which of the following
laila [671]

Answer:

C. -5

Step-by-step explanation:

for g(x) =ax and f(x) = x, both are linear function. There is nothing to be upward or downward and both are lines nothing to compare its narrowness.

If g(x) = ax² vs f(x) = x²

Then a = -5 is the answer (-: downward and 5: vertical stretch)
