1319.25=776.50+41.75p (p is for the number of players)(Now we solve for x)
Subtract 776.50 from both sides: 542.75=41.75x
Divide both sides by 41.75: 13=x
Remember that x is for the number of players so there'll be 13 players going to the tournament.

-3
Answer:
x | -7 -5 -3
y | -21 -15 -9
Step-by-step explanation:
y = 3x
If x = -7 then y = 3 × (-7) = -21
x = -5 then y = 3 × (-5) = -15
x = -3 then y = 3 × (-3) = -9

The table represents the balance of Sylvia's loan, y, over a period of 24 months, x. She used technology to create the scatter plot shown and
determined the best fit equation to model the data, y=-382.05x +
25,077.40. Determine how long it will take to reach the given balances
Using the given linear function, it is found that:
The balance will be of approximately $17,000 in month 21.The balance will be of approximately $0 in month 66.What is the function for the balance?The balance after x months is modeled by:
y = -382.05x + 25077.4.
Hence, it will be of approximately $17,000 at x for which y = 17000, hence:
17000 = -382.05x + 25077.4
x = (25077.4 - 17000)/382.05
x = 21.
We apply the same logic to find when it will be of approximately 0.
0 = -382.05x + 25077.4
x = (25077.4 - 0)/382.05
x = 66.

The critical value for z for a hypothesis test using a 5% significance level is 1.65
It is given that the reporter wants to test the store's claim against the alternative hypothesis that the wait time is actually greater than 60 minutes.
It is required to find the critical value for z for a hypothesis test using a 5% significance level.
What is a normal distribution?It is defined as the continuous distribution probability curve which is most likely symmetric around the mean. At Z=0, the probability is 50-50% on the Z curve. It is also called a bell-shaped curve.
We have a hypothesis H1 that wait time is actually greater than 60 minutes.
H1(T>60)
This is the case of the right-tailed hypothesis.
We have a significance level = 5% ⇒ 0.05
The statistics follow a normal distribution curve
Critical value = 1.6449 ≈ 1.65 (from the table at 5% significance level)
Thus, the critical value for z for a hypothesis test using a 5% significance level is 1.65

Is the following shape a rectangle? How do you know?
Answer:
B.Yes,the adjacent sides are perpendicular,and the opposite sides are parallel
Answer:
B. Yes, the opposite sides are perpedicular, and the opposite sides are parallel
Step-by-step explanation:
This is because for a rectangle to be a rectangle, it has to have four sides whose opposite sides are equal (so parallel) and adjacent sides meets at 90° (so perpendicular), both of which this shape is shown to be.

Long-billed curlews eat many different kinds of insects, including grasshoppers, as a source of food. It has been shown that pesticide use kills many of these insects. How would you expect an increase in pesticide use to affect to the population of long-billed curlews in the same area
An increase in the use of pesticides in the same area would lead to the population of long - billed curlews decreasing.
How will the population of long-billed curlews be affected by pesticides ?An increase in pesticide use that kills many of the insects that long-billed curlews eat, such as grasshoppers, would likely have a negative impact on the population of long-billed curlews in the same area.
Since grasshoppers and other insects are a primary food source for long-billed curlews, a decline in insect populations due to pesticide use could lead to reduced food availability and increased competition for remaining food sources. This could lead to decreased population size and potentially even local extinctions.

C = 2πr ( r is the radius )
given C = 14 , then
2πr = 14 ( divide both sides by 2 )
πr = 7 ( divide both sides by π )

Leo buys pasta for 12 people,
(a)
Each person eats 100 grams of pasta.
One packet has 500 grams of pasta.
How many packets must Leo buy?
Answer:
3
Step-by-step explanation:
If each packet has 500 grams, and each person eats 100 grams, then one packet will feed five people (500/100=5). Since he will be buying pasta for 12 people, he will need to buy three packets, because 3*500=1500 grams. While there is some extra, buying only two packets would result in not enough pasta.

231.48 cm²
Step-by-step explanation:
Formulae
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Area of a semicircle = 1/2 πr²
To find the shaded area:
Find the area of the rectangle. Subtract the area of the semicircle from the rectangle. Add this to the area of the triangle.
Area of the rectangle:
= 12 x 21
= 252 cm²
Area of the semicircle:
= 1/2 π(12 ÷ 2)²
= 1/2 · 3.14 · 6²
= 1/2 · 3.14 · 36
= 56.52 cm²
Area of the triangle:
= 1/2 x 6 x 12
= 36 cm²
Shaded area:
= area of rectangle - area of semicircle + area of triangle
= 252 - 56.52 + 36
= 194.48 + 36

The value of expression 8 divided by 4 (3-1) would be equal to 1
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of 8 divided by 4 (3-1)
A negative divided by a negative is positive, therefore,
8 / 4 (3-1)

What is the area of the playground shown? The edges of the playground meet at right angles, except for the edge whose length is not given. Show all work.
Answer:
520,000
Step-by-step explanation:
1400 x 200 = 280000
(400 + 800) x 400 /2 = 240000
240000 + 280000 = 520000
The area of the playground is 520000 square feet.
What is the area?The area is the amount of area occupied by an object's flat (2-D) surface or shape.
Given that the edges of the playground meet at right angles, except for the edge whose length is not given.
And to find the area of the composite figure,
find all the areas separately.
There is a square with a side length of 400 feet.
A rectangle with dimensions 200 feet by 600 feet.
Another rectangle with dimensions 1400- 600 = 800 feet by 200 feet.
And a triangle with a base of 400 feet and a height of 400 feet.
The area of the playground = (400 x 400) + (200 x 600) + (800 x 200) + (1/2 x 400 x 400)
The area of the playground = 160000 + 280000 + 80000
The area of the playground is 520000 square feet.
Therefore, the area is 520000 square feet.
