Jacob wanted to know what the most popular sneakers brand was for his classmates. His class had 30students. To save time he asked the first 10 boys he met. Is this a random sampling for the brand of sneakers? Why or why not?

Answers

Answer 1

No. This is not random sampling as the students chose are not chosen at random. Random sampling would be something done where each sample has equal probability of being chosen. Clearly this is not random sampling.

Group of answer choices

140

40

50

12

Answers

Answer:

B. 40

Step-by-step explanation:

If line ps intersecting with line qr at point t as shown, then ∠ P T Q = ∠RTS (oppositely directed angle)

Given

PTQ is x + 28

RTS is 2x + 16

Since they are both equal, then x+28 = 2x+16

collect like terms

x-2x = 16-28

-x = -12

multiply both sides by -1

-1(-x) = -1(-12)

x = 12

Since ∠ P T Q = x+28, substitute x = 12 into the function

∠ P T Q = 12+28

∠ P T Q = 40

Hence measure of ∠ P T Q is 40°

Answers

Answer:

It's a bit hard to explain, in my opinion. but I'll give it a go. Lets say you have 10 full pizzas, and you want to split it upon 5 people. Now 5 2 slices is 10, like 5x2 so basically, it's kind of like backwards multiplying. if that makes sense. Think of it like this. if you see something like 14 ÷ 2, think of what number times 2 would be 14. 7, exactly. So Just write the number thats missing. Thats how i like to think of it. What number is missing.

Step-by-step explanation:

Sorry if this doesnt make sense and sorry if you dont understand.

I just started 6th grade so im not sure if i had the right idea in my noggin

it’s hard to explain but let’s say you have 20 dogs and then you take 10 of them away and sell them. that would be 20 divided by 2 because 10 plus 10 = 20

i hope this helps!!

another example

you have 15 apples you give 3 family each 5 apples that would be 15divided by 3 =5

i really hope this helps! thanks!

Answers

Answer: t 0<t<3

Step-by-step explanation:

Answer:

The correct option is 1.

Step-by-step explanation:

The given graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.

The value of height and time can not be negative, there the values of h and t must be greater than 0.

The set of all possible inputs is called domain. In the graph x axis represent the domain and y-axis represent the range.

The graph is defined from t=0 to t=3.

Therefore option 1 is correct.

a) Work out the value of 5^2 – 1^5× 2^4
b) Work out the value of 7^2 + 4^3 ÷ 2^5

Answers

First you have to know BODMAS/BIDMAS (idk if all schools teach it like this) but this is the order in which you complete questions so it’s Brackets, Indices, Division/Multiplication, Addition/Subtraction
a) 5^2 is 5x5 which equals 25 1 to the power of anything is always 1 and 2^4 is 2x2x2x2 which is 16
So 5^2-1^5x2^4 = 25-1x16 which is then 25-16 = 9
b) 7^2+4^3 divided by 2^5 so 7^2 is 7x7 which = 49 then 4^3 means 4x4x4 = 64 and 2^5 is 2x2x2x2x2 which equals 32 so
7^2+4^3 divides by 2^5 is 49+64/32 = 49+2 which is 51

- If JL = 5x + 2, find JL.

Answers

Answer:

JL= 62

Step-by-step explanation:

27+3x-1=5x+2

3x+26=5x+2

3x+24=5x

24=2x

12=x

now plug in x(which is 12) for JL

5(12)+2

60+2

=62

The measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

JL = 5x + 2

From the line segment:

JL = 27 + 3x - 1

Plug the value of JL in the equation:

5x + 2 = 27 + 3x - 1

After solving:

5x - 3x = 26 - 2

2x = 24

x = 12

JL = 5x + 2

Plug x = 12 in the above equation:

JL = 5(12) + 2

JL = 60 + 2

JL = 62 units

Thus, the measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.
