Answer:
The width of the rectangle is 6,105 yards, and the length of the rectangle is 13,105 yards.
Step-by-step explanation:
Given that a rectangular garden covers 80 square yards, and the length is 7 yd longer than the width, to find the length and width of the rectangle the following calculation must be performed, knowing that the area of a rectangle arises from multiplying its width by its length:
X x (X + 7) = 80
5 x 12 = 60
6 x 13 = 78
8 x 14 = 112
6.1 x 13.1 = 79.91
6,105 x 13,105 = 80
Therefore, the width of the rectangle is 6,105 yards, and the length of the rectangle is 13,105 yards.
A license plate begins with three letters. If the possible letters are A, B, C, D and E, how many different permutations of these letters can be made if no letter is used more than once?
Answer:
60 different permutations of these letters can be made.
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
How many different permutations of these letters can be made if no letter is used more than once?
3 letters from a set of 5. So
[tex]P_{(5,3)} = \frac{5!}{(5-3)!} = \frac{5!}{2!} = 5*4*3 = 60[/tex]
60 different permutations of these letters can be made.

What is the value of this number in decimal form?
Three hundred sixty-seven thousandths.
Step-by-step explanation:
the other answer is correct.
just for a little bit of explanation :
the first position after the decimal point is for tenths. the second position for hundredths. the third for thousandths. then ten-thousandths, hundred-thousandths, millionths, ...
so, you would need 1000 thousandths to have a 1 at the first position before the decimal point. everything less than that has to be a number after the decimal point. and thousandths have to end (writing from left to right) with the thousandths-position. hundredths with the hundredths-position and so on.

c. The effect of training on how long it takes to solve the problem was not significant, F(27, 2)-4.47, p >.05.
d. The effect of training on how long it takes to solve the problem was significant, F(2, 29) - 4.47. p ,05.
Answer:
The answer is "Option b"
Step-by-step explanation:
Through this context, it is determined that the p-value is much less than 0.05, which is 0.021, so the rejection of the null hypothesis at 5%. There should be enough evidence to demonstrate that now the effect of the organization was substantial on how long it has taken to solve the issue. This result is statistically important.
The correct conclusion about this data is (b) The effect of training on how long it takes to solve the problem was significant, F(2, 27) = 4.47, p < 05.
From the table, we have the following values
F = 4.467
df between group = 2
df within group = 27
To reference the result, we make use of:
F(df between group, df within group) = F value
So, we have:
F(2, 27) = 4.47
The above result shows the F value approximated to two decimal points
Hence, the correct conclusion about this data is (b) The effect of training on how long it takes to solve the problem was significant, F(2, 27) = 4.47, p < 05.

Draw a negative linear relationship. Label it R. Along a curve showing a linear relationship, how does y change for each increase in x of one unit? For each increase in x of one unit, y _______.
Answer:
For each unit increase in x ; y decreases by 2 units.
Step-by-step explanation:
A negative relationship between two variables, X and Y is depicted d on a scatter plot by a negative trend line or slope. A negative relationship is interpreted as the decrease in variable X as Y increases or vice versa.
The scatter plot attached is related by the linear model :
y = - 2x + 110
Here, the slope of the plot is - 2 ; this means that for every unit increase in x - axis, then the y values decrease by 2 units.

If two cards are randomly selected, what is the probability of drawing any one suit first, followed by drawing a face card
Answer:
0.0181 = 1.81% probability of drawing a suit first, and then a face card.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of drawing a suit first:
4 out of 52 cards are suits, so:
[tex]P(A) = \frac{4}{52} = \frac{1}{13}[/tex]
Followed by drawing a face card:
Considering a suit was drawn, there will be 12 faces in the 51 remaining cards. So
[tex]P(B|A) = \frac{12}{51}[/tex]
What is the probability of drawing a suit first, followed by drawing a face card?
[tex]P(A \cap B) = P(A) \times P(B|A) = \frac{1}{13} \times \frac{12}{51} = \frac{12}{13*51} = 0.0181[/tex]
0.0181 = 1.81% probability of drawing a suit first, and then a face card.
The local pavilion is hosting an outdoor concert. There are both lawn seats and reserved seating available. Lawn seats cost
$10, while reserved seats are $25. A sponsoring business has given the school $375 to purchase seats. If the school
purchased 30 seats using all of the money, how many lawn seats and how many reserved seats did the sponsoring business
purchase?
The business purchased ____ lawn seats and _______ reserved seats
Let the lawn seats purchased by the business be : L
Let the reserved seats purchased by the business be : R
Given :
⊕ Cost of each lawn seat : $10
⊕ Cost of each reserved seat : $25
⊕ Sponsoring business has given the $375 to purchase seats
⊕ School purchased 30 seats using all of the money
⇒ L + R = 30 ---------- (1)
⇒ 10L + 25R = 375 ----------- (2)
Multiplying equation (1) with 10, we get :
⇒ 10L + 10R = 300 ------------- (3)
Subtracting equation (3) from equation (2), we get :
⇒ 10L + 25R - (10L - 10R) = 375 - 300
⇒ 25R - 10R = 75
⇒ 15R = 75
⇒ R = 5
Substituting R = 5 in equation (1), we get :
⇒ L + 5 = 30
⇒ L = 25
Answer: The Business purchased 25 lawn seats and 5 reserved seats

800 3. Andrew is buying a farm and needs to determine the height of a tree on the farm. Andrew, who is 5.8 feet tall, notices that when his shadow is 10 feet long, the shadow of the tree is 85 feet long. How tall is the tree? (5 points)
9514 1404 393
Answer:
49.3 feet
Step-by-step explanation:
Shadow lengths and object heights are considered to be proportional, so we have ...
tree height/(tree shadow) = Andrew's height/(Andrew's shadow)
height / (85 ft) = (5.8 ft)/(10 ft)
height = (85 ft)(5.8/10) = 49.3 ft
The tree is 49.3 feet tall.

There are 3 red marbles, 5 green marbles, and 2 blue marbles in a bag. Which of the following are true?
The probability of randomly drawing a red marble and then a green marble is .
The probability of drawing a green marble is the same as the probability of drawing either a red or a blue marble.
The probability of randomly drawing either a red marble or a green marble is 80%.
The probability of not drawing a blue marble is 20%.
Step-by-step explanation:
If there are 3 red marbles, 5 green marbles, and 2 blue marbles, we can find the probability of finding one of them easily.
1. If we add these numbers up, we get 10, so the red marbles plus the green marbles = 8 and then there are 2 blue ones. This means that there is an 80% chance of pulling a red or a green marble. Number one is correct.
2. The probability of drawing a red marble followed by a green marble depends on each individual probability. For a red marble, that is [tex]\frac{3}{10}[/tex] = 30% chance, and a green marble is [tex]\frac{5}{10}[/tex] = 50% chance. Since we are drawing out of 20 marbles (Two sets of ten), we can conclude that the chances for red are [tex]\frac{6}{20}[/tex]; green's chances are [tex]\frac{10}{20}[/tex], and blue's chances are [tex]\frac{4}{20}[/tex]. Assuming that we draw a red marble first, there is a [tex]\frac{6}{20}[/tex] chance of that. There is a [tex]\frac{10}{20}[/tex] chance of drawing a green, so we can conclude that the probability of drawing a red marble followed by a green marble is [tex]\frac{4}{20}[/tex] ([tex]\frac{10}{20}[/tex] - [tex]\frac{6}{20}[/tex]), witch is not [tex]\frac{1}{6}[/tex]. Number two is incorrect .
3. The probability of drawing a blue marble is 20%, so the probability of not drawing a blue marble is 80%. Number three is incorrect.
4. The probability of drawing a green marble is 50% and the probabilities of red and blue combined are equal to 50% (3 red + 2 blue = 5, and their are 5 green marbles therefore 50 50 chance). Number four is correct.
Answer:
The probability of randomly drawing a red marble(red 3) and then a green (green 5) marble is [tex]\frac{1}{6}[/tex] .
The probability of drawing a green marble is the same as the probability of drawing either a red or a blue marble.
The probability of randomly drawing either a red marble or a green marble is 80%.
