Step-by-step explanation:
\(7y = 8x - 14\)
get rid of the Y and put in a 6
\(7(6) = 8x - 14\)
\(7 \times 6 = 42\)
\(42 = 8x - 14\)
we need to get rid of the negative 14 so its only 8x.
to get rid of 14 on one side you add it to the other
\(42 + 14 = 56\)
\(56 = 8x\)
to get X by itself have to divide 8 by both sides
\(56 + \div 8 = 7\)
\(8x \div 8 = x\)
\(x = 7\)

Step-by-step explanation:
class of 30 students with 14 boys and 16 girls must select 4 leaders. how many ways are there to select the 4 leaders so that at least one girl is selected?
Answers
To solve this problem, we can use the concept of combinations. We want to select 4 leaders from a group of 30 students, so the total number of ways to select 4 leaders is:
30C4 = (30*29*28*27)/(4*3*2*1) = 27,405
Now, let's consider the number of ways to select 4 leaders where no girls are selected. Since there are 16 girls in the class, we must select all 4 leaders from the group of 14 boys. The number of ways to do this is:
14C4 = (14*13*12*11)/(4*3*2*1) = 10,626
Therefore, the number of ways to select 4 leaders where at least one girl is selected is:
27,405 - 10,626 = 16,779
So there are 16,779 ways to select the 4 leaders so that at least one girl is selected.

Answers
The value of ln150 is 5.0106, rounded to 4 significant figures.Note: ln is the natural logarithm which is a logarithm to the base e.
Given ln5
=1.6094 and ln6
= 1.7918, we need to find the value of the following logarithm without using a calculator i.e. ln150.Steps to find the value of ln150 using the properties of logarithm:First, we should simplify the expression. We know that 150 is not a power of 5 or 6, so we can't use the properties of logarithms to directly simplify ln 150. So we need to split 150 into factors of 5 and 6: 150
= 5 × 5 × 6.Next, we can use the following properties of logarithms:loga(xy)
= loga(x) + loga(y) and loga(x/y)
= loga(x) − loga(y).So, ln150
= ln(5 × 5 × 6)
= ln(5) + ln(5) + ln(6)Using ln5
=1.6094 and ln6
=1.7918ln150
= 1.6094 + 1.6094 + 1.7918
= 5.0106.The value of ln150 is 5.0106, rounded to 4 significant figures.Note: ln is the natural logarithm which is a logarithm to the base e.

Answers
The independent events P(AUB) = P(A) + P(B) is C.0.55
What is meant by independent events ?If the occurrence of one event has no bearing on the likelihood that the other will follow, then the two events are independent. The likelihood that both events A and B will occur is defined mathematically as being equal to the product of the probabilities of A and B, which are independent of the occurrence of other events. For instance, if we roll the same dice twice, the results are independent of one another. If knowing whether A happened has no effect on the likelihood of B, then the two events are independent. Mathematically, it is possible to state that P(B|A) = P(B) P(A and B) = P(B A) = P(B) P (A).sincerely,
P(A) = 0.35 and P(B) =0.20
P(AUB) = P(A) + P(B)
P(AUB) = 0.55

Scarlett has the deluxe version of the card game Mysterious Monsters of the Deep with 3D images printed on the playing cards. She randomly selects one card from the deck, puts it back in the deck, and picks another card. She repeats this several times and gets 2 anglerfish, 3 vampire squids, 1 viperfish, 4 megamouth sharks, and 5 ghost fish.
Based on the data, what is the probability that the next card Scarlett selects will have an anglerfish on it?
Answers
The probability that the next card Scarlett selects will have an anglerfish on it is 2/15, or approximately 0.1333.
To find the probability of selecting an anglerfish on the next card, we need to calculate the ratio of the number of anglerfish cards to the total number of cards in the deck.
From the given information, Scarlett selected 2 anglerfish cards during her previous selections.
The total number of cards she selected is 2 + 3 + 1 + 4 + 5 = 15.
Therefore, the probability of selecting an anglerfish card on the next draw is 2/15.
Calculate the total number of cards Scarlett selected.
2 + 3 + 1 + 4 + 5 = 1
Calculate the number of anglerfish cards Scarlett selected.
Scarlett selected 2 anglerfish cards.
Calculate the probability of selecting an anglerfish card on the next draw.
Probability = Number of anglerfish cards / Total number of cards
Probability = 2 / 15
Probability ≈ 0.1333
Thus, the probability that the next card Scarlett selects will have an anglerfish on it is 2/15, or approximately 0.1333.

The valid C++ assignment statements among the options are:

c. x = 2.5 * x;
a. This statement assigns the value of `i` plus 5 to `i`. It is a valid assignment statement.
b. This statement, `x + 2 = x;`, is not a valid assignment statement because the left-hand side of the assignment operator (`=`) should be a variable or a modifiable l-value expression, not an Arithmetic statement
c. This statement multiplies the value of `x` by 2.5 and assigns the result back to `x`. It is a valid assignment statement.
d. This statement, `percent = 10%;`, is not a valid assignment statement. To assign a percentage value, you should provide the value in decimal form, such as `percent = 0.1;` for 10%.

assume baldwin is producing 2,325 units of brat next year. what would brat's plant utilization be?
Answers
The plant utilization for brat would be 77.5% if Baldwin is producing 2,325 units of brat next year.
The plant utilization for brat would depend on the capacity of the plant and the production level achieved. Without knowing the capacity of the plant, it is difficult to provide an accurate calculation. However, assuming that the plant has a capacity of 3,000 units and Baldwin is producing 2,325 units, the utilization would be calculated as follows:
Utilization = (Actual Production / Maximum Production Capacity) x 100
Utilization = (2,325 / 3,000) x 100
Utilization = 77.5%
Therefore, the plant utilization for brat would be 77.5% if Baldwin is producing 2,325 units of brat next year.

Answers
Adam Vinatieri made 14 field goals and 7 extra points.
Given that,
a field goal is 3 points and the field goal after a touchdown is only 1 point.
Adam Vinatieri made 21 field goals and extra point kicks for 49 points.
Let x be the number of field goals and y be the extra point kicks.
So we get,
x + y = 21 -------------(1)
3x + y = 49 -----------(2)
Subtracting equation (1) from equation (2),
2x = 28
x = 14
putting the value of x in equation (1),
14 + y = 21
y = 7
Therefore Adam Vinatieri made 14 field goals and 7 extra points.
Field goal means a score of three points in football made by drop kicking or placekicking the ball over the crossbar from ordinary play. A field goal is a successful kick of the ball by a kicker through the goalpost. It is an offensive play that can score three points for a team.

To warm up, Coach Hadley had his swim team swim twelve 5–meter long laps. It took the team 5 minutes to finish the warm up. How fast did the team swim in centimeters per second?
Answers
The team swam at a speed of 20 centimeters per second during their warm up.
First, let's convert the length of one lap from meters to centimeters:
5 meters = 500 centimeters
So, the team swam 12 laps of 500 centimeters each, for a total distance of:
12 laps × 500 centimeters/lap = 6000 centimeters
Next, let's convert the time from minutes to seconds:
5 minutes = 300 seconds
To find the speed in centimeters per second, we can divide the distance by the time:
speed = distance ÷ time = 6000 centimeters ÷ 300 seconds
simplifying, we get:
speed = 20 centimeters/second
Therefore, the team swam at a speed of 20 centimeters per second during their warm up.
