Step-by-step explanation:
An airline has two flights each day from City A to City B. A random sample of 10 morning flights left the gate an average of 15 minutes late with a standard deviation of 5 minutes. A random sample of 10 evening flights left the gate an average of 20 minutes late with a standard deviation of 3 minutes. Suppose both the morning and evening flights are 30 minutes late. To determine which flight is more late than usual, first find the z-scores. Round to one decimal place if necessary.
Answer:
Step-by-step explanation:
Let X denote the random variable that obeys the normal distribution.
Given that:
For morning flights
Mean [tex]\mu_1[/tex] = 15
standard deviation [tex]\sigma_1[/tex] = 5
Sample size [tex]n_1[/tex] = 10
[tex]X_1 \sim Normal ( \mu_1, \sigma _1)[/tex]
The Z - score is calculated as:
[tex]Z = \dfrac{x_1 - \mu_1}{\sigma_1}[/tex]
[tex]Z = \dfrac{30 -15}{5}[/tex]
[tex]Z = \dfrac{15}{5}[/tex]
Z = 3
For evening flights
Mean [tex]\mu_2[/tex] = 20
standard deviation [tex]\sigma_2[/tex] = 3
Sample size [tex]n_2[/tex] = 10
[tex]X_2 \sim Normal ( \mu_2, \sigma _2)[/tex]
[tex]Z = \dfrac{x_2 - \mu_2}{\sigma_2}[/tex]
[tex]Z = \dfrac{30 -20}{3}[/tex]
[tex]Z = \dfrac{10}{3}[/tex]
Z = 3.33
Hence, from the above z-scores, we will realize that the evening flight is more late than usual.

An alloy is a mixture of metals.Suppose that a certain alloy is made by mixing 70 grams of an alloy that contains 12% copper with 90 grams of pure copper.
Answer the questions below. Do not do any rounding.
(a) How many grams of copper are in the resulting mixture?
Il grams
(b) What percentage of the resulting mixture is copper?
Answer:
(a) How many grams of copper are in the resulting mixture?
= 160 grams
(b) What percentage of the resulting mixture is copper?
= 61.5%
Step-by-step explanation:
(a) How many grams of copper are in the resulting mixture?
From the question: Suppose that a certain alloy is made by mixing 70 grams of an alloy that contains 12% copper with 90 grams of pure copper.
The number of grams of copper in the resulting mixture = 70 grams + 90 grams = 160 grams
(b) What percentage of the resulting mixture is copper?
70 grams of an alloy that contains 12% copper = 70 × 12%
= 70 grams × 0.12
= 8.4 grams
The number of grams of copper in the resulting mixture = 160 grams
The percentage of the resulting mixture that is copper is
=( 8.4 grams + 90 grams of pure copper/160) × 100
= 98.4/160 × 100
= 61.5%

to
y = mx + b form
Answer:
y = - [tex]\frac{1}{10}[/tex] x + 3
Step-by-step explanation:
Given
x + 10y = 30 ( subtract x from both sides )
10y = - x + 30 ( divide all terms by 10 )
y = - [tex]\frac{1}{10}[/tex] x + 3

Find the product
(4x-5)(4x-1)
Answer:
80
Step-by-step explanation:
(4x-5)(4x-1) = 80
Answer:
16x² - 24x + 5
Step-by-step explanation:
Given
(4x - 5)(4x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(4x - 1) - 5(4x - 1) ← distribute both parenthesis
= 16x² - 4x - 20x + 5 ← collect like terms
= 16x² - 24x + 5

Add 3 level scoops of mini chocolate chips and 1 level scoop of raisins to Container 1. If each scoop has the same number of items, what percent of the items in Container 1 are mini chocolate chips? (This value is known as the percent concentration of chips.) Explain how you decided. Label the container appropriately Answer: 50% because when there is only 2 variables and they are each 1 cup there is an even amount of stuff and when you ask for only one percentage that would be 50% because everything is even. Even if you asked for the percentage for the cup of raisins it would also be 50% Add 2 scoops of mini chocolate chips and 3 scoops of raisins to Container 2. What is the percent concentration of mini chocolate chips? Explain how you decided. Label the container appropriately. Stir the chips and raisins in each container to ensure that the chips and raisins are evenly mixed.
Answer:
Container 1
The percentage of mini chocolate chip is 3/4 * 100= 75 % to raisins.
Container 2
The percentage of mini chocolate chip is 2/5 * 100= 40 % to raisins.
Step-by-step explanation:
Container 1
Mini Chocolate Chips: Raisins
3 scoops: 1 scoop
The percentage of mini chocolate chip is 3/4 * 100= 75 % to raisins.
Container 2
Mini Chocolate Chips: Raisins
2 scoops: 3 scoop
The percentage of mini chocolate chip is 2/5 * 100= 40 % to raisins.
This is simplified with the help of the ratios . We find out the ratio of the mini chocolate to the total of both the ratios and mulitply it with 100 to get the percentage concentration.

On a coordinate plane, a curved line labeled f of x with a minimum value of (1.9, negative 5.7) and a maximum value of (0, 2), crosses the x-axis at (negative 0.7, 0), (0.76, 0), and (2.5, 0), and crosses the y-axis at (0, 2).
Which statement is true about the graphed function?
F(x) 0 over the intervals (-∞, -0.7) and (0.76, 2.5).
F(x) 0 over the intervals (-0.7, 0.76) and (0.76, ∞).
Answer:
The answer is D
Step-by-step explanation:
EDGE2020
The answer is:
A) F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5)
F(x) is the output, or y values, and the y values on this coordinate plane from (negative infinity, -0.7) to (0.76, 2.5) do not have values above 0. Hence, F(x) is less than 0 over the given intervals.
The ratio of red marbles to black marbles is 4:7. If the bag consists of 77 marbles in all, how many red marbles are in the bag?
Step-by-step explanation:
The ratio of red marbles to black marbles = 4 : 7

4x + 7x = 77
11x = 77
x = 77/11
x = 7

what is the area of the figure to the nearest hundredth renter the answer in the box 2yd 4yd
Answer:
9.57 yd squared
Step-by-step explanation:
we can divide this figure into two shapes: a rectangle and a semi-circle
since we know the length and width of the rectangle, all we ahve to do is multiply them together to find the area: 8 yd squared
for the semi-circle, we know the area is [tex]\frac{\\\pi r^2}{2\\}[/tex]
raduis is half the diameter so 1 yd
[tex]\frac{3.14(1)^2}{2}[/tex]
[tex]\frac{3.14}{2}[/tex]
1.57 yd squared
lastly, add the area of the two figures together 8+1.57
