ANSWER FOR BRAINLIEST

Answers

Hi there!

[tex]\large\boxed{182}[/tex]

Equation:

5a² - 2a - 10 for a = -6.

Evaluate by plugging in -6 for a:

5(-6)² - 2(-6) - 10 =

5(36) - (-12) - 10 =

180 + 12 - 10 = 182.

Answer:

x=2, x=1/2, x=-2/3

Step-by-step explanation:

First factor and get (x-2)(2x-1)(3x+2)=0

Then you set each of these parentheses individually equal to 0. x-2=0, 2x-1=0, 3x+2=0. Then you just simplify these to get your final answer that I showed above.

These two lines are graphs of non-proportional relationships. What makes them non-proportional?

Answers

Answer:

These two lines are graphs of non-proportional relationships because

" They do not go through the origin " ⇒ B

Step-by-step explanation:

If two quantities x and y are proportional, then

The relationship between them is represented by the equation y = k xk is the constant of proportionalityThe relationship represents graphically by a line must pass through the origin point

From the given graph

∵ The first line intersects the y-axis at point (0, 3)

∴ The line does not pass through the origin

∴ The line is a graph of the non-proportional relationship

∵ The second line intersects the y-axis at point (0, -2)

∴ The line does not pass through the origin

∴ The line is a graph of the non-proportional relationship

These two lines are graphs of non-proportional relationships because

" They do not go through the origin "

Step-by-step explanation:

These Two Graphs Are non proportional because C)They do no go through the graphs

Kevin has four apples in a boat each apple weighs 60 G and the empty bowl weighs 40 grams what is the total weight of the four apples with the bow

Answers

9514 1404 393

Answer:

  280 g

Step-by-step explanation:

The total weight is the sum of the weights of the objects:

 total = bowl + apple + apple + apple + apple

We use multiplication to simplify repeated sums:

  total = bowl + 4 × apple

  total = (40 g) + 4 × (60 g) = 40g + 240 g

  total = 280 g

The bowl and 4 apples weighs 280 grams.

HELP ASAP! What are the slope and y-intercept of the linear function that is represented by the table?
A. The slope ls -2, and the y-intercept is 6.
B. The slope ls -2, and the y-intercept is 12.
C. The slope is 2, and the y-intercept is 6.
D. The slope is 2, and the y-intercept is 12.​

Answers

Answer:

A

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use two points and find slope initially so,

(-3,18) (0,12)

18-12=6   ,  -3-0= -3

so the slope is 6/-3 = -2 so by this answer is either a or b .

further apply y =mx + c as it linear to find c

y= -2x + c

0 = -2x6 + c

c = 12

so slope is -2 , c is 12

The amount of gasoline G sold each month to customers at Bob's Exxon station in downtown Navasota is a random variable. This random variable G can be described as having a normal distribution with mean 2500 gallons and a standard deviation of 250 gallons (and there is no seasonal variation in sales). Exxon will give Bob an all-expense paid trip to College Station, including a free dinner at Burger King, if his station pumps more than 3000 gallons in any one month.


Required:

What is the probability that Bob will win that wonderful trip on the basis of his gasoline sales this month?

Answers

Answer:

The probability is [tex]0.0228[/tex]

Step-by-step explanation:

Let's start by defining the random variable [tex]G[/tex] as :

[tex]G:[/tex] '' The amount of gasoline sold each month to customers at Bob's Exxon station in downtown Navasota ''

Therefore, if [tex]X[/tex] is a continuous random variable that has a normal distribution, we write [tex]X[/tex] ~ [tex]N[/tex] ( μ , σ )

Where ''μ'' is the mean and ''σ'' is the standard deviation.

For the random variable [tex]G[/tex] we write :

[tex]G[/tex] ~ [tex]N(2500,250)[/tex]

We need to find [tex]P(G>3000)[/tex]

In order to calculate this, we are going to standardize the variable. This means, finding the equivalent probability in a normal random variable

[tex]Z[/tex] ~ [tex]N(0,1)[/tex]

We perform this because the random variable [tex]Z[/tex] ~ [tex]N(0,1)[/tex] is tabulated in any book or either you can find the table on Internet.

To standardize the variable we need to subtract the mean and then divide by the standard deviation ⇒

[tex]P(G>3000)[/tex] ⇒ P[ (G - μ) / σ > [tex]\frac{3000-2500}{250}[/tex] ] ⇒ [tex]P(Z>2)[/tex]

Because (G - μ) / σ  ~ [tex]Z[/tex]

Finally, [tex]P(G>3000)=P(Z>2)[/tex] ⇒ [tex]P(Z>2)=1-P(Z\leq 2)[/tex] = 1 - Φ(2)

Where '' Ф(x) = [tex]P(X\leq x)[/tex] '' represents the cumulative function of [tex]Z[/tex]

Looking for  Φ(2) in any table,

[tex]P(G>3000)=P(Z>2)=1-P(Z\leq 2)=1-0.9772=0.0228[/tex] ≅ %2.28

We found out that the probability is [tex]0.0228[/tex]

$3.29 for 9.25 ounces


How much is it per ounce?

Answers

Answer:

About $0.36 per ounce

Step-by-step explanation:

Set up a proportion.

Let p = price per ounce

3.29/p = 9.25 ounces/(1 ounce)

9.25p = 3.29

p = 3.29 ÷ 9.25

p = 0.3556756757

We can say 35 cents per ounce or 36 cents per ounce if rounded to 2 decimal places.

Suppose you scored 95 on a measure where the mean was 110 and the standard deviation was 15. Assuming a normal distribution, what percentage of scores should fall between your score and the mean?

Answers

Answer:

34% of scores should fall between your score and the mean.

Step-by-step explanation:

Let X denote the score.

It is provided that X follows a normal distribution with mean 110 and standard deviation 15.

A students score, x = 95.

Compute the probability of scores that should fall between the student's score and the mean as follows:

[tex]P(95<X<110)=P(\frac{95-110}{15}<\frac{X-\mu}{\sigma}<\frac{110-110}{15})[/tex]

                            [tex]=P(-1<Z<0)\\\\=P(Z<0)-P(Z<-1)\\\\=0.50-0.15866\\\\=0.34134\\\\\approx 0.34[/tex]

Thus, 34% of scores should fall between your score and the mean.
