Answer:
C. (-3, 2, -1)
Step-by-step explanation:
There are two types of matrices. One is REF and the other is what makes REF simpler--RREF. We use RREF to solve for REF because it makes the solution easy to find. RREF is displayed in your problem... it means that it's already solved, so the answers are already given on the right side, which is -3,2,-1. This only works with the combination provided (with the 0s and 1s). Otherwise, you'd have to solve.

Alia and her husband have a list of six names for their new baby boy. Each name is equally likely to be picked. They make the table to assign each name a number, then they roll a die 150 times. The results are in the table. Select all the true statements.
Answers
Answer:
3 and 4 are the only true statements.
Step-by-step explanation:
1 is incorrect because the experimental probability is calculated by dividing 24 by 150, which gives us 0.16 or 16%, not 0.15 or 15%.
2 is wrong because 6 ÷ 150= 0.04, giving each number a 4% chance of occurrence.
3 is correct because Karl occurs 28 of the 150 times. 28 ÷ 150= 0.1866666666666667, which is 18.66666666666667%, or about 19%.
4 is also correct because the theoretical probability of each name is 25.
5 is false because the experimental probability of Martin, Paxton, and Sal were less than the theoretical probability.

Answer:
25
Step-by-step explanation:
4a +12 -2c + c
4( ) + 12 - 2( ) + ( )
4(4) + 12 - 2(3) + 3
16 + 12 - 6 + 3
28 - 6 + 3
22 + 3
25
Helping in the name of Jesus.
Therefore, 4a + 12 - 2c + c = 25
Step-by-step explanation:a = 4
c = 3
Swap letters for numbers:4a + 12 - 2c + c
(4)(4) + 12 - (2)(3) + 3
16 + 12 - (2)(3) + 3
28 - (2)(3) + 3
28 - 6 + 3
22 + 3 = 25
Draw a conclusion:
Hence your answer is:4a + 12 - 2c + c = 25

Answer:
w≥77
Step-by-step explanation:
Multiply 11 by 7.
Answer:
\(w\geq 77\)
Step-by-step explanation:
How would you get w by itself so that it makes it simplify?
Either you Multiply/Divide and Subtract/Add.
In your case you have \(\frac{w}{7} \geq 11\)
To get w by itself you multiply 7 to both side leaving w.
\(7*\frac{w}{7}\geq 11*7\)
Seven cancel out on the left side leaving w.
11 * 7 = 77.
\(w\geq 77\)
Consider the situations in the table below
Situation A: A hang glider descended 33.57 feet, and then ascended 14.98 feet.
Situation B: A football team gained 7 2/5 yards in one play, and then lost 3/5 of a yard in the next play.
Situation C: A hiker walked 3 1/6 miles yesterday and 2 1/2 miles today.
Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

A small business that makes candles uses a proportional amount of essential oil and wax. For 132 ounces of wax, they use 11 ounces of essential oil.
How many ounces of essential oil is needed for 648 ounces of wax?
A. 54 ounces
B. 58.9 ounces
C. 121 ounces
D. 15.9 ounces
Answers
Answer:
A
Step-by-step explanation:
By proportion, ounces of essential oil for 648 ounces of wax
= 11 * 648/132
= 7128/132
= 54 ounces.
Answer: A - 54 ounces
Step-by-step explanation:
132 divided by 11 ounces = 12
First, you need to figure out the dividend that is giving you the wax-to-oil ratio. Since that is 12, we will divide the new amount of wax by that.
648 divided by 12 = 54

Answers
Answer:
Step-by-step explanation:
A ratio is a comparison of two numbers or measurements. The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces.

A weather balloon has a volume of 90.0 L when it is released from sea level 101 kPa. What is the atmospheric pressure on the balloon when it has grown to a size of 175.0 L?
Answers
Answer:
The final atmospheric pressure is 5.19 · 10⁴ Pa
Step-by-step explanation:
Assuming that the temperature of the air does not change, we can use Boyle's law, which states that for a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume. In formula,
pV = const.
where p is the gas pressure and V is the volume
The equation can also be rewritten as
p₁ V₁ = p₂ V₂
where in our problem we have:
p₁ = 1.03 · 10₅ Pa is the initial pressure (the atmospheric pressure at sea level)
V₁ = 90.0L is the initial volume
p₂ is the final pressure
V₂ = 175.0L is the final volume
Solving the equation for p2, we find the final pressure:
p₂ = p₁ v₁ divided by V₂ = (1.01 · 10⁵)(90.0) divided by 175.0 = 5.19 · 10⁴ Pa
The histogram shows the number of points scored by a basketball team for one season. A histogram titled points scored in one season shows the number of games in which a certain number of points were scored. The data is as follows. 69 to 76 points: 3 games. 77 to 84 points: 6 games. 85 to 92 points: 8 games. 93 to 100 points: 1 game. According to the histogram, in what percentage of games did the team score between 77 and 92 points? Enter your answer in the box. Round your answer to the nearest percent.
Answers
Find the total number of games with points scored between 77 & 92 pts - 14
To find the percentage divide 14/18 - .777
Multiply .777*100 - 77.7
Round to 78%
Percentage of games the team scored between 77 and 92 is 77.7% .
Given data from the histogram shows the number of games that are played in the range of 77 - 92.
Total number of games played = 18
Number of games played in the range 77 - 92 = 14
Percentage of games played in the range 77-92 = (Number of games played in the range 77 - 92) / (Total number of games played) × 100
Percentage = (14)/(18) × 100
= 77.7% .
Hence the number of games played in the given range is 77.7%.

What is P(less than 5)?
Write your answer as a fraction or whole number.
Answers
Answer:
this probability is 3/4.
Step-by-step explanation:
The spinner has the numbers 2, 3, 4, and 5. Since the question asks for the probability of spinning a number less than 5, we need to consider the numbers 2, 3, and 4.
Out of the four numbers on the spinner, three of them (2, 3, and 4) are less than 5.
Therefore, the probability of spinning a number less than 5 is 3 out of 4.

You spin the spinner once.
