We examine a population with normal distribution having mean of 1000 and standard deviation 50. What percentage of the population lies between 850 and 1150?

The function is supposed to be;

h(x) = -343^(x)

Answer:

The domain will be a set of real numbers while the range will be y ≤ 0 and on the interval (-∞, 1)

As x is increasing, h is decreasing and as x is decreasing, h is increasing

Step-by-step explanation:

We are given the function as;

h(x) = -343^(x)

The formula is;

y = a^(x) since it's symmetrical to the x-axis

However in this case;

y = -a^(x)

Now, the domain is y and the range is a set of values of x.

I've attached a graph of this function drawn on desmos.

From the graph we can see that The domain will be a set of real numbers while the range will be on the interval (-∞, 1)

For a value of x = 0,we have;

h(0) = -343^(0)

h(0) = -343

When we increase the value of x to 3,we have;

h(3) = -343^(3)

h(3) = -40353607

When we decrease the value of x to -3, we have;

h(-3) = -343^(-3)

h(-3) = 0.00000002478

Thus, we can conclude that;

As x is increasing, h is decreasing and as x is decreasing, h is increasing

Answer:

220 pancakes could feed 80 people.

Step-by-step explanation:

Since the Cheer Team is cooking for a fundraiser breakfast, and they know that 22 pancakes can feed 8 people, to determine the number of people that can be fed 220 pancakes it is necessary to perform the following calculation:

22 = 8

220 = X

(220 x 8) / 22 = X

1760/22 = X

80 = X

Therefore, 220 pancakes could feed 80 people.

Answer:B(4,6)

Step-by-step explanation: ima pro at math

3*4=12+           6*4=24

=36

The linear equation representing the situation is 3x + 4y = 36 and the coordinate (4, 6) represents the solution of this linear equation.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is Evan who earns money for doing chores. He earns $3 for putting away laundry and $4 for unloading the dishwasher.

Assume that [x] represent the number of times Evan puts away the laundry and [y] represent the number of times he unloads the dishwasher.

The total money Evan needs = $36.

We can write the linear equation representing the situation is as follows -

3x + 4y = 36

It can be seen that, the coordinate (4, 6) would be the solution of the linear equation as -

3 x 4 + 4 x 6 = 12 + 24 = 36

Therefore, the linear equation representing the situation is 3x + 4y = 36 and the coordinate (4, 6) represents the solution of this linear equation.

Answer:

The correct answer is C. 4.5 pounds.

Step-by-step explanation:

Since Ben bought a bag of potatoes that weighed 2.25 pounds, 2 boxes of raisins that total weighed 0.750 pounds (0.375 x 2), and 2 bags of apples that weighed 3 pounds total (1.5 x 2), the total weight of the merchandise purchased by Ben was 6 pounds.

Now, since his brother carried a bag of apples, which weighed 1.5 pounds, the total weight carried by Ben was 4.5 pounds (6 - 1.5).

Answer:

37.5%

Step-by-step explanation:

The computation is shown below:

Here we assume that the 1st, 2nd and 3rd child be the triplet and it could be either a girl or boy

Now

B = Boy

G = Girl

The possible triplets are

(BBB) (BBG) (BGB) (BGG) (GBB) (GBG) (GGB) (GGG)

These are 8 triplets

Now find the sets that involves 2 boys and a girl

(BBG) (BGB) (GBB)

Now the probability is

P = 3 ÷ 8

= 37.5%

Answer:

x= 28 /89

Step-by-step explanation:

3x(32)=7x+28

Step 1: Simplify both sides of the equation.

96x=7x+28

Step 2: Subtract 7 from both sides.

96x   7x+28

−7             −7

89x=28

Step 3: Divide both sides by 89.

89x /89 = 28 /89
