EASY 7TH GRADE MATH, WILL GET BRAINLIEST
Answer:
C. $45
Step-by-step explanation:
If 2 pounds of coffee costs $17.95, we divide this number by two to get the cost of one pound of coffee.
This value is equal to $8.975 and we multiply this number by 5 to get 5 pounds of coffee.
This is about equal to option C. $45
How do I graph the line with slope of 3 and Y-intercept if -6?
Step-by-step explanation:
For drawing the graph , we Firstly need to find the equation of the line . We can find the line using Slope intercept form . Here ,
y intercept = (-6)slope = 3 .We know slope intercept form as ,
[tex]\implies y = mx + c \\\\\implies y = (3)x + (-6) \\\\\implies \boxed{\boxed{y = 3x - 6 }}[/tex]

What is the volume of a sphere with a diameter of 9.9 cm, rounded to the nearest
tenth of a cubic centimeter?
Answer:
the volume of the sphere is 507.78981 cm^3
Step-by-step explanation:
The computation of the volume of the sphere is given below:
Given that
The Diameter is 9.9 cm
So, the volume of the sphere is
= 4 ÷ 3 ×π × r^3
= 4 ÷ 3 × 3.14 × 9.9 ÷ 2^3
= 4 ÷ 3 × 3.14 × 4.95^3
= 507.78981 cm^3
Here r denotes the radius
And, the radius would be comes by dividing the diameter from 2
Hence, the volume of the sphere is 507.78981 cm^3

In a random sample of 5 residents of the state of Maine, the mean waste recycled per person per day was 2.6 pounds with a standard deviation of 0.69 pounds. Determine the 98% confidence interval for the mean waste recycled per person per day for the population of Maine. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
(1.307 ; 3.893)
Step-by-step explanation:
Given that:
Mean, xbar = 2.6
Standard deviation, s = 0.69
Sample size, n = 5
Confidence interval : xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Degree of freedom (df) = n - 1 = 5 - 1 = 4
Hence Tcritical = 3.747
Margin of Error = 3.747 * 0.69/sqrt(4)
Margin of Error = 1.293
Lower boundary = (2.6 - 1.293) = 1.307
Upper boundary = (2.6 + 1.293) = 3.893

Answer:
40units²
Step-by-step explanation:
find the shapes you know the formula of. There's two shapes a rectangle and a trapezoid.
do the formula for rectangle
A = bh
A = 8×2
A = 16
Now the formula for Trapezoid
A = 1/2h(b+b)
A = 1/2×4(4+8)
A = 1/2×4(12)
A = 1/2(48)
A = 24
16+24 = 40

Answer:
80 degrees
Step-by-step explanation:
The only given angle here is angle 4, which measures 100 degrees.
1) Identify angle relationships
Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.
2) Solve for angle 6
180-Angle 4=Angle 6
180-100=Angle 6
80=Angle 6
Therefore, the measure of angle 6 is 80 degrees.
I hope this helps!
Answer:
c. 80°
Step-by-step explanation:
We are given a shape with a bunch of lines, and are asked to find what measure is ∠6.
Solving this is simple, we just need to keep notice that what angle is larger than 90 degrees looks like and what under 90 degrees looks like. All angles that are above 90 look wide and huge, while all under is very tiny and skinny.
If we take a look at our hint, angle 4 has the (100 degrees). Look at how wide it is, if angle 6 is tinier than that, then the answers A. and B. are scratched out.
Now 90 degrees is a right angle, looking at angle 6 guarantees that D. is also not correct because it is not a right angle.
Leaving us with C. 80
What are the foci of the ellipse given by the equation 225x^2+144y^2=32,400?
Answer: look at the picture
Step-by-step explanation: Hope this help :D
The foci of the ellipse given by the equation 225x² + 144y² = 32,400 is located at (±15, 0).
What is Conic section?A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane.
The equation of an ellipse with major axis length 2a and minor axis length 2b can be written as:
(x/a)² + (y/b)²= 1
In this case, a = 15 and b = 12.
The equation of the ellipse can be written as:
(x/15)² + (y/12)² = 1
Multiplying both sides of the equation by 225×144 = 32,400 gives us:
225x² + 144y² = 32,400
The foci of an ellipse are located at (±a, 0).
Therefore, the foci of this ellipse are located at (±15, 0).

Bob has a bulb factory that produces white light bulbs. He sold some bulbs to Peter claiming that on average the service life of his bulbs is at least 980 hours. To test this claim Peter gathered information on the 20 bulbs purchased. He found that the mean service life is 960 and knows that the variance of service life for the population is . Which of the following statements properly analyzes Bob’s claim? Assume that the distribution service life of bulbs is normal.
a. Using a t-test you conclude that both types of bulbs have different mean service life at the 5% level.
b. Using a t-test you conclude that both types of bulbs have the same mean service life at the 5% level.
c. Using a z-test you conclude that both types of bulbs have the same mean service life at the 5% level.
d. Using a t-test you conclude that both types of bulbs have the same mean service life at the 1% level.
e. Using a z-test you conclude that both types of bulbs have different mean service life at the 5% level.
Answer:
a. Using a t-test you conclude that both types of bulbs have different mean service life at the 5% level.
Step-by-step explanation:
The t test will be used as
1) the sample size is less than 30
2) the population standard deviation is knows and is s= √200= 14.142
Using the test statistic
t= x- u/ s/ √n
t= 960-980/ 14.142/ √20
t= -0.316
It is one tailed test as the claim is
H0: u ≥ 980 and the alternate hypothesis is Ha : u< 980
The critical region for one tailed test with n-1 = 20-1 = 19 degrees of freedom is t < 1.729 for ∝= 0.05
The critical region for one tailed test with n-1 = 20-1 = 19 degrees of freedom is t < 2.539 for ∝= 0.01
Since the calculated value of t= -0.136 falls in the critical region we conclude that the null hypothesis is false and the average life of the bulbs is less than 980. We accept the alternate hypothesis.

Luca decides to play Wheel of Letter. To play the game, contestants spin a wheel with 26 equal sections, letter A through Z. If the pointer lands on any letter in the phrase “COUNTRY PHRASE,” the contestant wins a prize.
What is the probability that Luca will win Wheel of Letters?
The probability that Luca will win Wheel of Letters for this considered case is 6/13
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, the sample space of result of wheel of letters spin is
S = {A, B, ..., Z} , thus, n(S) = size of S = 26
Let E = event that the spinner will stop in one of the letters in “COUNTRY PHRASE”
Then, the outcomes in favor of E are {'P', 'O', 'C', 'A', 'T', 'R', 'Y', 'N', 'H', 'S', 'U', 'E'}
Thus, n(Favorable cases for E) = 12 (counted unique ones, and not repeated), as each letter is only 1 time in the spinner.
Thus, we get:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{12}{26} =\dfrac{6}{13}[/tex]
Thus, the probability that Luca will win Wheel of Letters for this considered case is 6/13

a total of 216 cookies for a wedding party. How long will it take her?
Proportions pls
Answer:
108 Hours or 4.5 days
Step-by-step explanation:
216/2= 108 hours
108/24= 4.5 days
Answer:
9 hours
Step-by-step explanation:
1 dozen is 12
She makes 24 cookies every hour
Since she has to make a total of 216 cookies, and our objective is to find out how long she will take, then we will divide 216 by 24 and multiply the given number by the amount of hours taken to make 24 cookies.
216/24 = 9
Since 216 divided by 24 is equal to 9, then it will take Sarah 9 hours to make 216 cookies.
