Answer:

Step-by-step explanation:

Let x = the age of Thomas

Let x + 6 = the age of Huilan

x + x + 6 = 70

2x + 6 = 70

2x = 64

x = 32 years

x+6 = 38 years

Answer:

dependent events are if the outcome of one event affects the outcome of another

Answer:

Step-by-step explanation:

The given expression is

[tex]a_{k}=8+(k-1)2[/tex]

Where [tex]d=2[/tex] and [tex]a_{1}=8[/tex].

The number of stitches in the n row are expressed as

[tex]a_{n} =8+2n-2\\a_{n} =2n+6[/tex]

Therefore, the n row has [tex]2n+6[/tex] stitches.

Notice that the result is an expression, that is beacuse the problem is asking for a general solution, it's asking for the n row, which refers to certain row in general terms.

1st question: C

2nd : 8

3rd : 46

4th : 540

Answer: I believe the answer is 14.04

Step-by-step explanation:

When you divide 3.24 into 3 it gives you 1.08 then multiply it by 13 to get 14.04

Answer:

14.04

Step-by-step explanation:

You have 3 apples. Those 3 apples cost 3.24. He also wants to buy 13 MORE. You find the answer for doing a diagram like this:

A- 3 A- 13

$- 3.24 $- ?

Step 1. Do the diagram and fill it out.

Step 2. Multiply 13 and 3.24

(You get 42.12)

Step 3. Divide the answer (42.12) by 3

(You get 14.04)

And thats how you get the answer.

The correct option is The mode for the students is 2 and the mode for the teachers is 4.

To determine the mode of a data set, one must identify the number(s) that appear most frequently. In the dot plot for the students, the number of siblings that appears most frequently is 2, as there are 7 dots above the number 2 on the number line. This makes 2 the mode for the students' data.

 For the teachers' data, the number of siblings that appears most frequently is 4, with 5 dots above the number 4 on the number line. Therefore, 4 is the mode for the teachers' data.

 Comparing the modes of the two data sets, we have:

- Mode for students: 2

- Mode for teachers: 4

The other options provided do not accurately reflect the modes of the data sets based on the given dot plots.

Step-by-step explanation:

The population is the entire group of customers who bought tablets, totaling 570 people. The sample is the subset of 300 customers who were randomly chosen to receive the survey.

In the given scenario, an electronics store has conducted a survey among its customers who purchased tablets. To identify the population and the sample in this context, we look at the definitions of each term. The population is the entire group that is the focus of the study, while the sample is a subset of the population that is surveyed to represent the whole.

The population in this case includes all the customers who bought tablets during the previous month, which totals to 570 people. The sample is the group of customers who were selected to receive the survey. Since surveys were sent to 300 of these customers at random, the sample size is 300.

Therefore, the correct identification is: The population is 570. The sample is 300.

Answer:

C

Step-by-step explanation:

Use distributive property. distribute the 2 into both numbers by multiplying them both by 2 and you get 2x + 14

Answer:

I believe the answer is (C) 2x+14.

You have to distribute the 2 and multiply it to the x and the 14.

Step-by-step explanation:

Multiply the x by the 2 to get 2x

multiply the 7 by the 2 to get 14

so the equation is: 2x + 14

I hope this is correct.

Answer:

See below

Step-by-step explanation:

2x+4 / x^2-x-6

= 2(x+2)/(x-3)(x+2)

= 2/(x-3)

So the 2 expressions are equivalent

The values of x which make the expressions undefined are those values which make the denominators 0

For 2x+4/ x^2-x-6 they are X=3 and x= -2.

For 2/x-3 they are x =3.

Answer:

D. 13

Step-by-step explanation:

well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-

x= -b±[tex]\sqrt{b^{2}-4ac}[/tex] /2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since [tex]\sqrt{13^{2}-4*1*(-30)[/tex] = [tex]\sqrt{289}[/tex] = 17. So b=13.

Answer:

the center is (-2,3)

Step-by-step explanation:

The required graph that represents circle  (x + 2)² + (y - 3)² = 25  is given below in the image.

graph represents the circle (x + 2)2 + (y - 3)2 = 25 to determine.

The area of the circle is given by the pie times square of the radius.

Area of circle = πr^2

Standard form of the equation of circle = ( x - h ) ²+ ( x - y )² = r²
Where r is the circle's radius and h and k is the circle's center.
Given equation of the circle =  (x + 2)² + (y - 3)² = 25
where center is ( -2, 3 )
radius r = √25 = 5

While plotting a circle on a graph marks the center at ( -2, 3 ) radius. and draw the circle of radius 5 around the center ( -2, 3 ). The result is shown in the image.

Thus, the required graph that represents circle (x + 2)² + (y - 3)² = 25. is given below in the image.

The prism has a volume of 5 cubic unit is option (C) [tex]1\frac{1}{4}[/tex] unit, 4 unit and 1 unit

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface

A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.

Here,

Volume of prism = l × w × h

Option 1

Volume = [tex](1\frac{1}{2})(3)(1) =\frac{9}{2}[/tex] cubic units

Option 2

Volume = [tex](2)(2)(1\frac{1}{2})=6[/tex] cubic units

Option 3

Volume = [tex](1\frac{1}{4})(4)(1)=5[/tex] cubic units

Option 4

Volume = [tex](2)(1)(2)=4[/tex] cubic units

Hence, The prism has a volume of 5 cubic unit is option (C) [tex]1\frac{1}{4}[/tex] unit, 4 unit and 1 unit
