Answer:
[tex]x=11\\[/tex]
Step-by-step explanation:
[tex]6x^2=726[/tex] First, you need to divide everything by 6.
[tex]x^2=121[/tex]Then you put everything in a radical to get this:
[tex]x=11[/tex]
Answer:
[tex]6 {x}^{2} = 726 \\ \frac{6 {x}^{2} }{6} = \frac{726}{6} \\ {x}^{2} = 121 \\ x = \sqrt{121} \\ x = 11[/tex]
compounded monthly P=\$2,000 , r=3\% , t = 5years
To calculate the compound interest, use the formula A = P (1 + r/n)^(nt). For the given values, the final amount after 5 years of monthly compounded interest on $2,000 can be calculated.
Explanation:To calculate the compound interest, we can use the formula:
A = P (1 + r/n)^(nt)
Where:
A = final amount
P = principal amount ($2,000)
r = annual interest rate (3%)
t = time in years (5 years)
n = number of times the interest is compounded per year (12 for monthly compound interest)
Plugging in the values, we have:
A = 2000 (1 + 0.03/12)^(12*5)
Simplifying the equation will give us the final amount after 5 years of monthly compounded interest on $2,000.

if the mean is 120 and the standard deviation in 24 what is the score that is 3 standard deviations above the mean
Answer:
192
Step-by-step explanation:
If the mean is 120 and the standard deviation is 24, then 3 standard deviations above the mean would be 24(3) = 72 + 120 = 192.
192 is the score that is 3 standard deviations above the mean.
What is standard Deviation?The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Given:
Mean= 120
Standard Deviation = 24
So, the score for 3 standard deviations above the mean
= 24(3) + 120
= 72 + 120
= 192.
Hence, 192 is the score that is 3 standard deviations above the mean.

Choose the correct answer below.
A. 4(cos 48° + i sin 48°)
B. 4[(cos 54°- cos 6°)+i (sin 54°- sin 6°)]
c. 4{cos 9° + i sin 9°)
D. 4(cos 54° sin 6° + i sin 54° cos 6)
Answer:
A: 4(cos 48° + i sin 48°)
Step-by-step explanation:
The step by step working:
z1 = 20(cos 54° + i sin 54°)
z2 = 5( cos 6° + i sin 69°)
z1/z2 = (20/5)(cos 54° + i sin 54°)/(cos 6° + i sin 69°)
= 4[(cos 54° + i sin 54°)(cos 6° - i sin 6°)] / (cos^2 6° +sin^2 69°)
= 4[(cos 54° cos 6° - sin 54° sin 69°) + i(cos 54°sin 6° + sin 54° cos 6°)]
= 4(cos 48° + i sin 48°) (Using sum and difference identities)
The answer is A: 4(cos 48° + i sin 48°)

Bridget plans to attend 4 cardio classes and 5 weightlifting classes, which will last 328 minutes. Next week, she hopes to attend 4 cardio Classes and 1 weightlifting class, which will last 168 minutes. How long is each class?
Answer:
Time per cardio class: 32 minutes
Time per weightlifting class: 40 minutes
Step-by-step explanation:
Start by creating a system of equations:
let c = the time per cardio class
let w = the time per weightlifting class
4c + 5w = 328
4c + w = 168
Solving for c and w get you 32 minutes and 40 minutes respectively
Each cardio class lasts 32 minutes and each weightlifting class lasts 40 minutes.
To find out how long each class is, we need to set up a system of equations based on the information given.
Let's denote the duration of a cardio class by C minutes and the duration of a weightlifting class by W minutes.
1. From the first week, we have the equation:
4C + 5W = 328
2. From the second week, we have:
4C + 1W = 168
3. To eliminate C, we can subtract the second equation from the first:
(4C + 5W) - (4C + 1W) = 328 - 168
4W = 160
W = 40
4. Now substitute W back into the second equation:
4C + 40 = 168
4C = 128
C = 32
Therefore, each cardio class lasts 32 minutes and each weightlifting class lasts 40 minutes.

Steven rolls a 6-sided nombre cube 3 times.What is the probability of rolling a multiple of 3 on all the rolls?
The probability of rolling a multiple of 3 on all three rolls of a 6-sided number cube is [tex]\( \frac{1}{27} \)[/tex].
To find the probability of rolling a multiple of 3 on all three rolls of a 6-sided number cube, we first need to determine the total number of outcomes and the number of favorable outcomes.
Total outcomes for each roll = 6 (since there are 6 sides on the cube).
Favorable outcomes for a multiple of 3 on each roll = {3, 6} (numbers divisible by 3).
Thus, the probability of rolling a multiple of 3 on each roll is 2 out of 6, or [tex]\( \frac{2}{6} \)[/tex].
Since each roll is independent, we multiply the probabilities of each roll:
[tex]\[ P(\text{multiple of 3 on all rolls}) = \left( \frac{2}{6} \right) \times \left( \frac{2}{6} \right) \times \left( \frac{2}{6} \right) \][/tex]
[tex]\[ P(\text{multiple of 3 on all rolls}) = \left( \frac{2}{6} \right)^3 \][/tex]
[tex]\[ P(\text{multiple of 3 on all rolls}) = \left( \frac{1}{3} \right)^3 \][/tex]
[tex]\[ P(\text{multiple of 3 on all rolls}) = \frac{1}{27} \][/tex]
So, the probability of rolling a multiple of 3 on all three rolls is [tex]\( \frac{1}{27} \)[/tex].

Chris is putting a new baseboard in his room . The bed is 15 meters long and the 9/10 meters wide . What is the area of the baseboard?
Answer:
The area of the baseboard is 13.5m²
Step-by-step explanation:
Given data
Length of the bed L=15m
Width of of the bed B=9/10m
Area of the board A=?
We know that the area of the board
Area A=length x width
Substituting our given data we have
A=15*9/10
A=135/10
A=13.5m²
Hence the area of the board is 13.5m²
The area of the baseboard that Chris needs to install in his room, represented as a rectangle with length 15 meters and width 9/10 meters, is 13.5 square meters.
Explanation:In the field of Mathematics, to find the area of a rectangle (which is the shape being represented by the baseboard's dimensions that Chris is working with), you multiply the length by the width. Given that the length of the bed is 15 meters and the width is 9/10 meters, the area of the rectangular baseboard can be found by multiplying these values. So, area = 15 meters * 9/10 meters = 13.5 square meters. Therefore, the area of the baseboard that Chris needs to install is 13.5 square meters.
