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.

Answer:

36

Step-by-step explanation:

x is the number

(x-11)(-5) = -125

x - 11 = 25

x = 25 + 11

x= 36

The inequality that models the scenario is the first one:

$24 + $2*n ≤ $37

Solving that we conclude that Eli can buy at most 6 notebooks.

We know that Eli wants to buy a calculator that costs $24 and some notebooks, such that each notebook costs $2.

Then If Eli buys the calculator and n notebooks the total cost will be:

$24 + $2*n

We know that Eli has a total of $37 to spend, so that is the maximum amount he can spend. Thus, we can write the inequality:

$24 + $2*n ≤ $37

So the correct option is the first one.

Now also let's solve the inequality for n.

$24 + $2*n ≤ $37

$2*n  ≤ $37 - $24

$2*n ≤ $13.

n ≤ $13/$2

n ≤ 6.5

So Eli can buy at most 6 notebooks.

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: 10^10

Step-by-step explanation:

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

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.

Stratified random sample would be the sampling design for the best information.

• In statistics, stratified sampling is an method of sampling from a population which can be divided into subpopulations. In surveys based on statistics, when subpopulation within an overall population var, it could be advantageous to sample each population separately.

• For example one may divide a sample of children into subgroups by age like 1-5,6-10,11-15 and above.

• The benefits of stratified sampling is that you can obtain reasonably precise estimate for subgroups related to the research.

• One disadvantage of stratified sampling is that the selection of appropriate strata for a sample of your research may be difficult.

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)
