I will have "x" represent the unknown number, or you could use a "?", doesn't matter.

8\leq \frac{x}{-4}     [8 is less than or equal to (≤) the quotient (÷) of a number and -4, so the number is being divided by -4]

If you need to solve this, you need to isolate/get the variable "x" by itself in the inequality:

8\leq \frac{x}{-4}   Multiply -4 on both sides to get rid of the fraction and get "x" by itself

(-4)8\geq \frac{x}{-4} (-4)    When you multiply/divide by a negative number, you flip the sign (< >)

-32 ≥ x          [-32 is greater than or equal to x, or x is less than or equal to -32]

The number of square feet per house are normally distributed with a population standard deviation of 137 square feet and an unkn
pshichka [43]

Answer:

Step-by-step explanation:

Given that X, the number of square feet per house is N(mean, 137)

Sample size = 19

Sample mean x bar =1350 sq ft

Since population std dev is given,

std error of sample = \frac{137}{\sqrt{19} } \\=31.43

Since sample size is small, t critical value can be used

df = 18

t value for 80% two tailed = 1.333

Margin of error = ±1.333(std error) = ±1.333*31.43\\=41.896

Confidence interval = sample mean ±margin of error

= 1350-41.896,1350+41.896\\=(1308.104,1391.896)

Use the function below to find F(3)
garik1379 [7]

Answer:

Theanswer is 4/27.

Step-by-step explanation:

given that, F(x) = 4×(1/3)^x

now , F(3)= 4×(1/3)^3 ( putting value of x)

or, F(3) = 4×(1/27)

therefore, F(3)= 4/27... ans
