____________________________________________________

Solve by simplifying:

-4x - (-x)

Distribute (or carry over) the minus sign into the variable inside the parenthesis, in which it turns into a positive.

-4x + x

Combine like terms by adding:

-3x

Your answer would be C. -3x

Write the equation of the circle with a center at (- 2, - 8) and a radius of sqrt(10) .
Neporo4naja [7]

Answer:

(x + 2)^2 + (y + 8)^2 = 10

Step-by-step explanation:

The general equation of a circle with center at (h, k) and radius r

is (x - h)^2 + (y - k)^2 = r^2.  If the center is at (-2, -8) and the radius is √10, then this equation becomes:

(x + 2)^2 + (y + 8)^2 = 10

A piece of rural land sold ten years ago for 40000. The price for the same land this year is $800 more per acre, and it sold for
Sholpan [36]

Answer: 25

Step-by-step explanation:

From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.

The size of the piece of land in acres will then be:

40000 + 800x = 60000

800x = 60000 - 40000

800x = 20000

x = 20000/800

x = 25

The land is 25 acres

Current research indicates that the distribution of the life expectancies of a certain protozoan is normal with a mean of 46 day
AysviL [449]

Answer: P(x ≥ 47) = 0.25

Step-by-step explanation:

Since the distribution of the life expectancies of a certain protozoan is normal, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = life expectancies of the certain protozoan.

µ = mean

σ = standard deviation

n = number of samples

From the information given,

µ = 46 days

σ = 10.5 days

n = 49

The probability that a simple random sample of 49 protozoa will have a mean life expectancy of 47 or more days is expressed as

P(x ≥ 47) = 1 - P(x < 47)

For x = 47

z = (47 - 46)/(10.5/√49) = 0.67

Looking at the normal distribution table, the probability corresponding to the z score is 0.0.75

P(x ≥ 47) = 1 - 0.75 = 0.25
