Answer:

n = q/10 - (r t)/10

Step-by-step explanation:

Solve for n:

q - 14 n = r t - 4 n

Subtract q - 4 n from both sides:

-10 n = r t - q

Divide both sides by -10:

Answer: n = q/10 - (r t)/10

Answer: C.-1.5

Step-by-step explanation:

Given: The burning time of a very large candle is normally distributed with mean[tex](\mu)[/tex] of 2500 hours and standard deviation[tex](\sigma)[/tex] of 20 hours.

Let X be a random variable that represent the burning time of a very large candle.

Formula: [tex]Z=\dfrac{X-\mu}{\sigma}[/tex]

For X = 2470

[tex]Z=\dfrac{2470-2500}{20}\\\\\Rightarrow\ Z=\dfrac{-30}{20}\\\\\Rightarrow\ Z=\dfrac{-3}{2}\\\\\Rightarrow\ Z=-1.5[/tex]

So, the z-score they corresponds to a lifespan of 2470 hours. =-1.5

Hence, the correct option is C.-1.5.

Answer: OK, stay with me on this one

the image is what your graph will look like, but with 2 lines instead of one. on the bottom, mark the months. on the side, write temperatures. Then on each month for the line for A, dot the temperature it is with a connected line. (Like the line is on the image.) Then do the same for the line for city B. I'd recommend doing it in 2 different colors, and label some where else which city.

Answer:

4) x = - 12

5) x = 4

Step-by-step explanation:

4)

Since points T and S are mid points of sides ML and MN of triangle MLN.

Therefore, by mid point theorem,

TS is half of LN

so,

[tex]x + 26 = \frac{1}{2} (x + 40) \\ \\ 2(x + 26) =x + 40 \\ \\ 2x + 52 = x + 40 \\ \\ 2x - x = 40 - 52 \\ \\ x = - 12[/tex]

5) In the same way x = 4 will be the correct answer in question number 5.

The amount that Andrea pay Dina for her share of the partnership will be $810,000

The percent of the business did Andrea own after she bought out Dina will be 80%.

The amount that Andrea pay Dina for her share of the partnership will be:

= 9/(7 + 9 + 4) × $1800000

= 9/20 × $1,800,000

= $810,000

The percent of the business did Andrea own after she bought out Dina will be:

= (7 + 9)/20

= 16/20 × 100

= 80%

Answer:

-1075

Step-by-step explanation:

The 64th term of the arithmetic sequence -4, -21, -38, .... is -1075.

Arithmetic sequences are a set of numbers written in an order where the difference of any two consecutive term will be a constant. This constant difference between the consecutive terms is called the common difference commonly denoted by 'd'. In other words, arithmetic sequences are formed by adding or subtracting a constant number to each term.

Arithmetic sequences are also known as arithmetic progression.

Here, the given sequence is -4, -21, -38, ...

Common difference, d = (-21) - (-4) = -21 + 4 = -17

First term, a = -4

We have to find the 64th term of this sequence.

nth term of an arithmetic progression is given by the formula,

aₙ = a + (n - 1)d

a₆₄ = -4 + [(64 - 1) × (-17)]

     = -4 + [63 × (-17)]

     = -4 + (-1071)

     = -1075

Hence the 64th term of the arithmetic sequence -4, -21, -38, .... is got as  -1075.

Mid point of the points PQ is (₋0.3 , 3.25)

Given points are:

P(₋2 , 2.5)

Q(1.4 , 4)

midpoint of PQ = ?

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.

The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.

Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)

we have two points:

P(₋2,2.5) = (x₁,y₁)

Q(1.4,4) = (x₂,y₂)

Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)

= (₋0.6/2 , 6.5/2)

= (₋0.3 , 3.25)

Hence we determined the midpoint of PQ as (₋0.3 , 3.25)
