Answer and Explanation

Since (x + 3)^2 => 0 for all x, the smallest value of the function P(x) would be 2

When (x + 3)^2 = 0

x = -3 and y value of P(x) would be 2 (because there’s a plus 2)

So the vertex of the minimum point is (-3,2).

A) Q(x) = (x + 3)^2 + 5

Vertex is (-3,5)

B) R(x) = (x + 3 - 6)^2 + 2

As the opposite happens when you’re transforming x value.

= (x - 3)^2 + 2

Vertex is (3,2)

C) S(x) = (x + 3 - 4) ^2 + 2 - 7

= (x - 1)^2 - 5

Vertex is (1,-5)

A manager asked her employees how many times they had given blood in the last year. The results of the survey are given below. T
stira [4]

<u>Complete Question</u>

The probability distribution table is given below:

\left|\begin{array}{c|ccccccc}x&0&1&2&3&4&5&6\\P(x) &0.33 &0.24& 0.16& 0.12 &0.08 &0.05& 0.02\end{array}\right|

Answer:

1.61

Step-by-step explanation:

The probability distribution table is given below:

\left|\begin{array}{c|ccccccc}x&0&1&2&3&4&5&6\\P(x) &0.33 &0.24& 0.16& 0.12 &0.08 &0.05& 0.02\end{array}\right|

We want to determine the mean number of times a person gave blood.

Expected Value, E(x)=\sum x_i\cdot P(x_i)

=(0 \times 0.33)+ (1 \times 0.24)+(2\times0.16)+(3\times0.12)+(4\times0.08)+(5\times0.05)+(6\times0.02)\\=0+0.24+0.32+0.36+0.32+0.25+0.12\\=1.61\\

The mean number of times a person gave blood based on this survey is 1.61.

vodka [1.7K]

Answer:

1. n + 8 = 10

2. \frac{n}{12}= 10

3. 8n - 6 = 34

4. 3(n + 12) = 45

5. No

6. Yes

Step-by-step explanation:

(only for questions 5 and 6)

5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.

6. If you substitute in b = 8, you get:

5(8-3)= 25\\5(5) = 25\\25 = 25

this is true.
