Answer: He is paid $90 last weekend.

Step-by-step explanation:

Since we have given that

Amount he earns per hour = $6

If he works on Saturday, he is paid time and a quarter .

Amount would be

6\times 1.25=\$7.5

If he works on Sunday, he is paid time and a half.

Amount would be

6\times 1.5=\$9

Number of hours he worked on Saturday = 6 hours

Number of hours he worked on Sunday = 5 hours

So, Total amount he is paid last weekend altogether is given by

6\times 7.5+5\times 9\\\\=\$90

Hence, he is paid $90 last weekend.

I believe the correct given equation is in the form of:

4 – 0.25 g + 0.5 h

Now we are to evaluate the equation with the given values:

g = 10 and h = 5

What this actually means is that to evaluate simply means to calculate for the value of the equation by plugging in the values of the variables. Therefore:

4 – 0.25 g + 0.5 h = 4 – 0.25 (10) + 0.5 (5)

4 – 0.25 g + 0.5 h = 4 – 2.5 + 2.5

4 – 0.25 g + 0.5 h = 4

 

Therefore the value of the equation is:

4

Lana and Jeff each randomly surveyed 15 students about their favorite types of movies. What would you expect to see in the sampl
Anon25 [30]

Answer:

  1. Listing of 15 students
  2. Assignment of a sequential number to each student.
  3. The figured out sample size, i.e., 2.
  4. Selected sample using sampling frame 15 from Step 2 and your sample size from Step 3, i.e., 2  

Step-by-step explanation:

Random sampling is a piece of the sampling method where each example has an equivalent likelihood of being picked. An example picked randomly is intended to be an impartial portrayal of the all out populace. On the off chance that for certain reasons, the example doesn't speak to the populace, the variety is known as a sampling mistake. A random example is an example that is picked randomly. It could be all the more precisely called a randomly picked test. Random examples are utilized to stay away from inclination and other undesirable impacts. Random sampling is probably the least complex type of gathering information from the all out populace. Under random sampling, every individual from the subset conveys an equivalent chance of being picked as a piece of the sampling procedure.

A sausage company makes two different kinds of hot dogs, regular and all-beef. Each pound of all-beef hot dogs requires 0.75 lb
Gre4nikov [31]

Answer:

  • 880 lbs of all-beef hot dogs
  • 2000 lbs of regular hot dogs
  • maximum profit is $3320

Step-by-step explanation:

We can let x and y represent the number of pounds of all-beef and regular hot dogs produced, respectively. Then the problem constraints are ...

  • .75x + 0.18y ≤ 1020 . . . . . . limit on beef supply
  • .30y ≤ 600 . . . . . . . . . . . . . limit on pork supply
  • .2x + .2y ≥ 500 . . . . . . . . . . limit on spice supply

And the objective is to maximize

  p = 1.50x + 1.00y

The graph shows the constraints, and that the profit is maximized at the point (x, y) = (880, 2000).

2000 pounds of regular and 880 pounds of all-beef hot dogs should be produced. The associated maximum profit is $3320.

Which expression can be used to find the sum of the polynomials? (9 – 3x2) (–8x2 4x 5)
SIZIF [17.4K]

For this case we have:

Polynomial 1: P (x) = 9-3x ^ 2

Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5

Sorting the polynomials:

Polynomial 1: P (x) = - 3x ^ 2 + 9

Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5

Adding term to term (similar) we have:

P (x) + Q (x) = (- 3-8) x ^ 2 + (0 + 4) x + (9 + 5)\\P (x) + Q (x) = - 11x ^ 2 + 4x + 14

Answer:

A (x) = P (x) + Q (x) = - 11x ^ 2 + 4x + 14
