1.

8 > 1  so:  a(x) = -4x + 7

a(8) = - 4(8) + 7 = - 32 + 7 = - 25

2.

-6 ≤ 1 ≤ 1   so:   a(x) = 2x - x²

a(1) = 2(1) - (1)² = 2 - 1 = 1

3.

-7 ≤ -6  so:  a(x) = |x - 8|

a(-7) = |-7 - 8| = |-15| = 15

4.

-6 ≤ -3 ≤ 1   so:   a(x) = 2x - x²

a(-3) = 2(-3) - (-3)² = -6 - 9 = - 15

5.

-6 ≤ -¹/₂ ≤ 1   so:   a(x) = 2x - x²

a(-¹/₂) = 2(-¹/₂) - (-¹/₂)² = - 1 - ¹/₄ = - 1¹/₄

6.

⁹/₄ > 1  so:  a(x) = -4x + 7

a(⁹/₄) = - 4(⁹/₄) + 7 = - 9 + 7 = - 2

(05.01)Which equation can be used to calculate the area of the shaded triangle in the figure below?
Marina86 [1]

Equation of shaded triangle is \frac{1}{2} (14\times8).

Solution:

Length of the rectangle = 14 ft

Breadth of the rectangle = 8 ft

Area of the rectangle = length × breadth

                                    = 14 × 8

In this rectangle the diagonal splits the rectangle into two equal halves.

Area of the shaded triangle = Half of area of rectangle

                                              $=\frac{1}{2} (14\times8)

Area of the shaded triangle = \frac{1}{2} (14\times8)

Hence the equation can be used to calculate the area of the shaded

triangle is \frac{1}{2} (14\times8).

inna [77]

Answer:

What is 0.42857142857 as a fraction?

To write 0.42857142857 as a fraction you have to write 0.42857142857 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.42857142857 = 0.42857142857/1 = 4.2857142857/10 = 42.857142857/100 = 428.57142857/1000 = 4285.7142857/10000 = 42857.142857/100000 = 428571.42857/1000000 = 4285714.2857/10000000 = 42857142.857/100000000 = 428571428.57/1000000000 = 4285714285.7/10000000000 = 42857142857/100000000000

And finally we have:

0.42857142857 as a fraction equals 42857142857/100000000000

Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on
FinnZ [79.3K]

The question is incomplete! Complete question along with answers and step by step explanation is provided below.

Question:

(a) Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial. Under what conditions is it appropriate to use a normal approximation to the binomial? (Select all that apply.)

nq > 10

np > 5

p > 0.5

np > 10

p < 0.5

nq > 5

(b) What is the probability of "12" or fewer successes for a binomial experiment with 20 trials. The probability of success on a single trial is 0.50. Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.)

Answer:

(a) The correct options are np > 5 and nq > 5

(b) P(x ≤ 12) = 0.8133

Step-by-step explanation:
