What is -8(v-3) = -2(-3v-5)

Scilla [17]

The answer is 1. v=1 because it eventually ends up being 7v=7 and it divides into 1.

2. 4A

3. 2M

4. 4X

5. 7D (left) 7x4 (right)

6. 2Y (left) 3Y (right)

Step-by-step explanation:

very simple for me, just take the variable or number on the left or right and multiply by the number on the top or bottom. And for problems with 2 variables do 2X or 2Y whatever the variable may be. Hope this helped

Alaskan Salmon are fished extensively to serve in restaurants. However, there are limits to how many and the size of fish which

TEA [102]

Answer:

The salmon size is less than equal to 10.28 inches represent bottom 25% of all salmon.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 12.5 inches

Standard Deviation, σ = 3.3

We are given that the distribution of salmon size is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.25

$P( X < x) = P( z < \displaystyle\frac{x - 12.5}{3.3})=0.25$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 12.5}{3.3} = -0.674\\\\x = 10.2758\approx 10.28$

Thus, the salmon size is equal to or less than 10.28 inches, they are considered small and young and represent bottom 25% of all salmon.

Use the key features of the polynomial f(x) = -4x^4 + 4x^3 + 9x^2 – 12x + 10 to describe its end behavior.

Black_prince [1.1K]

Answer:

The left side continues down, and the right side continues down

Step-by-step explanation:

f(x) = -4x⁴ + 4x³ + 9x² – 12x + 10

The leading term (-4x⁴) has an even exponent and a negative coefficient.

Since the exponent is even, the left and right ends will continue in the same direction.

Since the coefficient is negative, both ends will continue down.
