Exponential Rule [Powering]: $\displaystyle (b^m)^n = b^{m \cdot n}$

Step-by-step explanation:

Step 1: Define

Identify

r(x) = 4x² - 3x + 7

Step 2: Evaluate

Substitute in x [Function r(x)]: r(2a²) = 4(2a²)² - 3(2a²) + 7
Exponential Rule [Powering]: r(2a²) = 4(2²a²⁽²⁾) - 3(2a²) + 7
[Exponents] Multiply: r(2a²) = 4(2²a⁴) - 3(2a²) + 7
Exponents: r(2a²) = 4(4a⁴) - 3(2a²) + 7
Multiply: r(2a²) = 16a⁴ - 6a² + 7

Loia Piaza surveyed 872 customers to determite which of two new pizza cnoices to 425 said they would prefer the BBQ Ranch Pizza.

Firdavs [7]

Answer:

Correct option: fourth one -> 87.6% (it is missing the point between 7 and 6)

Step-by-step explanation:

We have a total of 872 customers surveyed, and from this total, 384 were male, so the number of female is 872 - 384 = 488

From the 488 female, we know that 171 females prefer the Buffalo pizza, so the number of females that prefer the bbq pizza is 488 - 171 = 317.

If 425 customers prefered the bbq pizza, we know that the number of customers that prefer the buffalo pizza is 872 - 425 = 447

To find the probability of a customer being female or prefering the buffalo pizza, we can use this formula:

N(female or buffalo) = N(female) + N(buffalo) - N(female and buffalo)

N(female or buffalo) = 488 + 447 - 171 = 764

So the probability of chosing a female or someone that prefer buffalo is:

P = N(female or buffalo) / N(total) = 764 / 872 = 87.6%

Correct option: fourth one (it is missing the point between 7 and 6)

–20, - 12,5, 22, . . . An= A50=

marshall27 [118]

Answer:

an = 17n - 46

a50 = 804

Step-by-step explanation:

-29, -12, 5, 22, ...

Subtract each number from the next one.

-12 - (-29) = 17

5 - (-12) = 17

22 - 5 = 17

The common difference is 17. This is an arithmetic sequence which starts with -29, and in which each subsequent value is 17 more than the previous value.

a1 = -29

a2 = -29 + 17

a3 = -29 + 2(17)

a4 = -29 + 3(17)

Notice that for each term, you have -29 and something added to it. What you add to -29 is 17 multiplied by 1 less than the number of the term. For term 1, 1 less than 1 is 0. You add 0 * 17 to -29 and get -29. term 1 is -29. For term 2, 1 less than 2 is 1. You add 1 * 17 to -29 and get -12, etc.

For term n, 1 less than n is n - 1. Add (n - 1) * 17 to -29 to get term n.

an = -29 + 17(n - 1)

This formula can be simplified.

an = -29 + 17n - 17

an = -46 + 17n

an = 17n - 46

a50 = 17(50) - 46

a50 = 804
