Answer:

<h3> x² - 9x + 16</h3><h3 />

Step-by-step explanation:

(-5x² - 9x + 6) + (6x² + 10)

= -5x² - 9x + 6 + 6x² + 10

=  6x² - 5x² - 9x + 6 + 10

=  x² - 9x + 16

According to the manufacturer of the candy Skittles, 20% of the candy produced are red. If we take a random sample of 100 bags o
igomit [66]

Answer:

Probability that the proportion in our sample of red candies will be less than 20% is 0.5 .

Step-by-step explanation:

We are given that 20% of the candy produced are red. A random sample of 100 bags of Skittles is taken.

The distribution we can use here is;

               \frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } } ~ N(0,1)

where, p = 0.20 and n = 100

Let \hat p = proportion of red candies in our sample

So, P(\hat p < 0.20) = P(\frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } } < \frac{0.20 - 0.20}{\sqrt{\frac{0.2 (1- 0.2)}{100} } } ) = P(Z < 0) = 0.5

Therefore, probability that the proportion in our sample of red candies will be less than 20% is 0.5 .

Which expression is equivalent to (x^2 -8) - (-2x^2+4)?​
Phoenix [80]

Answer:

D) 3x^2 - 12

Step-by-step explanation:

Using PEMDAS;

There is no need to evaluate the part of the equation (x^2 - 8) because is no need to, as it is already in its simplest form.

We must evaluate the part of the equation continuing with, "- (-2x^2+4)," as it is not in its simplest form.

Evaluating "- (-2x^2+4)":

Step 1: Distributing the negative

Once distributing the negative symbol amongst the values within the parenthesis according to PEMDAS, we get "2x^2 - 4" as the product.

Step 2: Consider the rest of the equation to evaluate

Since the part of the equation is still in play here as it is a part of the original equation to be solved, we must evaluate it as a whole to get the final answer.

Thus,

x^2 -8 + 2x^2 - 4 = ___

*we can remove the parenthesis as it has no purpose, since it makes no difference.

Evaluating for the answer, we get,

x^2+2x^2 + (-8 - 4) = 3x^2 - 12

Hence, the answer is D) 3x^2 - 12.

General Formulas and Concepts:
- Reading a Cartesian Plane
The y-intercept is the y-value when x = 0. It is also when the graph crosses the y-axis.
Step-by-Step Explanation:
According the the graph given, the graph crosses the y-axis at 2. Therefore, when x = 0, y = 2, and we have our y-int.

Answer:

Option A & D are correct Option.

Step-by-step explanation:

We are given with following :

Area of Base = 15 in.²

Height of Prism = 3 in.

Length of edge of base = 5 in.

Volume of Prism = Area of Base × Height = 15 × 3 = 45 in.³

Therefore, Option A & D are correct Option.
