What is the solution to –4|–2x + 6| = –24?x = 0x = 0 or x = –6x = 0 or x = 6no solution
Answers
The correct answers are the x = 6 and x = 0.
In order to find this, we can follow the order of operations.
–4|–2x + 6| = –24
Divide by -4
|–2x + 6| = 6
Since it is now equal to a absolute value, we have to solve for the positive and negative versions of the final answer. Let's start with the positive.
-2x + 6 = 6
-2x = 0
x = 0
Now for the negative
-2x - 6 = -6
-2x = -12
x = 6
These would be your two answers.

Answer: 9 houses
Step-by-step explanation:
Step 1:
Since 2/3 of the houses were sold last month, 1/3 of them were left.
45 * 1/3 = 15 houses left last month
Step 2:
Since 2/5 of the remaining houses were sold this month, 3/5 of them were left
15 * 3/5 = 9 houses left to be sold
there's your answer hope this helps :)

Answer:
87,010 cents is the SP.
Step-by-step explanation:
MP = $1400
VAT = 13%
Discount = 45%
so,
discount amount = 45% of MP
= 45% of $1400
= 45/100 * $1400
= 9/20 * $1400
= 9* $70
= $630
so,
MP - discount amount
= $1400 - $630
= $770(SP)
so,
VAT amount = 13% of SP
= 13% of $770
= 13/100 * $770
= $100.1
so,
SP + VAT
= $770 + $100.1
= $870.1
so,
$1 = 100 cents
$870.1 = 100*870.1
= 87,010 cents
B. 173.9 mg less than < mu μ less than <196.1 mg
C. 173.8 mg less than < mu μ less than <196.2 mg
D. 173.7 mg less than < mu μ less than <196.3 mg
Answers
Answer:
option (C) 173.8 mg less than < mu μ less than <196.2 mg
Step-by-step explanation:
Data provided ;
number of sample, n = 12
Mean = 185 milligram
standard deviation, s = 17.6 milligrams
confidence level = 95%
α = 0.05 [for 95% confidence level]
df = n - 1 = 12 - 1 = 11
Now,
Confidence interval = Mean ± E
here,
E is the margin of error =
also,
=
= 2.201 [ from standard t value table]
Thus,
E =
or
E = 11.182 milligrams ≈ 11.2 milligrams
Therefore,
Confidence interval:
Mean - E < μ < Mean + E
or
185 - 11.2 < μ < 185 + 11.2
or
173.8 < μ < 196.2
Hence,
the correct answer is option (C) 173.8 mg less than < mu μ less than <196.2 mg
Final answer:
To construct a confidenceinterval for the population mean cholesterol content of all chicken eggs with a 95% confidence level, we use the sample mean, standard deviation, and sample size to calculate the margin of error. The confidence interval is then constructed by subtracting the margin of error from the sample mean and adding it to the sample mean.
Explanation:
To construct a confidenceinterval for the population mean cholesterol content of all chicken eggs, we first need to find the margin of error. The margin of error depends on the samplemean, standard deviation, sample size, and the desired level of confidence. In this case, we have a sample mean of 185 mg, a standard deviation of 17.6 mg, and a sample size of 12. Since we want a 95% confidence interval, we use a z-score of 1.96. The margin of error is then calculated as 1.96 * (17.6/sqrt(12)), which is approximately 9.61 mg. We can then construct the confidenceinterval by subtracting the margin of error from the sample mean and adding it to the sample mean. Therefore, the 95% confidence interval for the true mean cholesterol content of all such eggs is 175.9 mg to 194.1 mg.
