1 answer:

4 0

-5(2x+1)-2x-2=17
first, distribute
-10x-5-2x-2=17
combine like terms
-12x-7=17
get the x alone, eliminate the constant
-12x=24
divide out the -12 to get the x alone.
x=-2

Using n = 3.14, find the area of a circle with a radius of 16.

KATRIN_1 [288]

Answer:

803.84=A

Step-by-step explanation:

The area of a circle can be found by using the equation $\pi r^{2}$ =A.

$\pi r^{2}$ =A

$(3.14)(16^{2})$ =A

(3.14)(256)=A

803.84=A and the units are, how ever the radius is measured cubed

the selling price of a television set is $125 more than twice the cost. find the cost if the selling price is $325.

OverLord2011 [107]

The cost is $100. Take $325, and subtract $125. It gives you $200. And you have to divide that in half cuz the price is twice the cost. So the cost is $100

The time (in number of days) until maturity of a certain variety of tomato plant is Normally distributed with mean μ. You select

VLD [36.1K]

Answer: 60.93 < μ < 69.07

Step-by-step explanation: The true mean of a set of data is between an interval of values with a percentage of precision, e.g., a <u>99% confidence interval</u> means we are 99% confident the true mean is between the lower and upper limits.

To find the interval, use

x± $z\frac{s}{\sqrt{n}}$

z is z-score related to the % of confidence level

In this case, a 99% confidence interval is 2.576

x is sample mean

Calculating:

$x=\frac{63+69+62+66}{4}$

x = 65

65± $2.576\frac{3.16}{\sqrt{4}}$

65±4.07

Confidence Interval: 60.93 < μ < 69.07

Meaning that we are 99% sure the population means is between 60.93 and 69.07.
