Answer:
5 preschoolers
Step-by-step explanation:
So this question states that yesterday, 10 preschoolers chose to play with stuffed animals and 10 different preschoolers chose to so other activities.
We can assume that there were 20 preschoolers at school yesterday (10 + 10 = 20).
From this given information, we can conclude that the preschoolers who would chose to play with stuffed animals would be the same amount at the preschoolers who would chose to do other activities.
Using all of the given information, we can also find that:
10/20 or 1/2 of the preschoolers would chose to play with the stuffed animals
and
10/20 or 1/2 of the preschoolers would chose to do other activities
We are then given that there are 10 preschoolers at school today. We are asked to find out how many of the preschoolers are expected to chose to play with the stuffed animals.
Previously, we found that 1/2 of the preschoolers yesterday chose to play with the stuffed animals. We can use this to find the expected amount of preschoolers who will chose to play with the stuffed animals today.
We can do this by multiplying 1/2 with the number of preschoolers today, or 10:
10 × 1/2 = 10/2 = 5
So it is expected that 5 preschoolers would chose to play with the stuffed animals today.
I hope you find my answer to be helpful. Happy studying.

Step-by-step explanation:
Howdy, did you do a, b, and c by yourself? Because there are some slight issues, so I'll do my best to explain.
a. 3x+5x
We know that x=2, so we can substitute 2 in for x right now, or we can combine like terms.
3x and 5x both have the variable x so we can add them easily to get 8x. If you substitute in 2, you're just multiplying 8×2, which is 16.
b. 5z+4z+z
Again, since
we know that z=-3, we can substitute in now, or we can combine like terms first. 5z, 4z, and z all have the variable x, we addition is easy. 5+4+1=10, so you'll have 10z. Substitute in -3 for z, and you're just multiplying 10×-3=-30
c. 3x+6+5x
This is trickier since 6 doesn't have the variable x. So to combine like terms means to only add 3x and 5x. So the equation will turn out looming like 8x+6. now substitute in 2 for x and you get
8(2)+6
16+6
22
d. 8y+8-4y
Combine like terms
4y+8
substitute in 5 for y
4(5)+8
20+8
28
e. 5z-4z+z
combine like terms
z+z
2z
substitute -3 for z
2(-3)

f. 3x+6+5x-2

(so that's 3x+5x and 6-2)

According to Newton's Second Law, if force equals 17 N and acceleration equals 8 m/s2, what is the mass in kilograms?
Answer as a number, rounded to the nearest thousandth?
Answers
Answer:
2.13kg
Step-by-step explanation:
fnet=ma
17=m(8)
17÷8 =m
2.13=m
Answer:
The mass is 2¹/₈, or 2.125, kg
Step-by-step explanation:
We know that force is equal to mass times acceleration, so given a force of 17 newtons and an acceleration of 8m/s², we can say:
[tex]f = ma\\m = f/a\\m = \frac{17\ N}{8\ m/s^2}\\m = \frac{17\ kg\times m/s^2}{8\ m/s^2}\\m = 17/8\ kg\\m = 2.125 kg[/tex]
giving us a mass of 2¹/₈, or 2.125 kg.
A large factory that builds machines has three shifts, one that starts at 4:00 A.M., one that starts at noon, and one that starts at 8:00 P.M. The manager of the factory wanted to know whether there is an association between an employee’s work experience (less than five years with the company, between five and twenty years with the company, over twenty years with the company) and the time of the employee’s shift. The manager selected a random sample of 125 employees and classified employees by their shift time and work experience. What is an appropriate pair of hypotheses for the manager to use?
Answers
Answer:
if the worker has more experience, then they will have longer shifts because they will be better at their job and be able to complete more tasks.
Step-by-step explanation:
use and "if then because" structure in a hypothesis, and use common logic based on the info provided :)
Answer:
[tex]H_{0}[/tex] : Work experience is independent of the time of an employee's shift
[tex]H_{A}[/tex] : Work experience is dependent on the time of an employee's shift
Step-by-step explanation:
Since we have one population but multiple variables, so we are using a chi-square test of independence. Thus, our null should be that there is no association, and the alternative that there IS an association.

B) 60.21 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches
8’6”=102’
14’2”=170’
Now find the area
1/2 x 102 x 170 = 8670 in²
This is one of the answers, but the quetion asks how many quart feet you need.
So, convert it back to feet.
8670 x 0.06944444444 = 60.2083333
(You could also have converted the two lengths to feet. 8’6” = 8.5 ft. 14’2” = 14.16666666. This way would probably have been faster.
1/2 x 8.5 x 14.166666 = 60.20833333)

Answers
Answer:
1. 3x-7y and -7y+3x
Step-by-step explanation:
1. 3x -7y and -7y +3x
This is correct because the terms remain unchanged. The -7y stays a -7y and the positive 3x stays a positive 3x.
2. 3x -7y and 7y -3x
This is not correct because the signs of the 3x and 7y switch. For the expressions to be equivalent, the signs must remain unchanged.
3. 3x -7y and 3y -7x
This is not correct because the variables of the 3 and 7 switched. The variables need to stay the same, for the expressions to be equivalent.
4. 3x-7 and -3y+7x
This is not correct because both the variables and the signs of the expressions changed. Both the signs and variables would need to stay the same in order to be equivalent.

Answer: y=-4x+6
Step-by-step explanation:
M is the slope in slope intercept form.
y=mx+b
And b is the Y intercept because when you plug in zero for x you get y=b.
So we know
y=-4x+b
Because m is the slope
And y is 6 because it is shown in the parentheses
So we know the answer is y=-4x+6

Answers
Answer: C 30 it was correct on my test
The estimated probability that at least two of the puppies will be female is 60%.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Let heads (H) be the female puppy
Let tails (T) be the male puppy.
The simulation results are the sample spaces.
[tex](THTT, TTTH, TTHH, HTTT, TTTT, HHHH, HTHT, HHHT, THTH, THTH)[/tex]
⇒ [tex]n(s)=10[/tex]
The event is the probability that at least two of the puppies will be
female.
[tex]e=(TTHH, HHHH, HTHT, HHHT, THTH, THTH )\\[/tex]
⇒ [tex]n(e)=6[/tex]
The estimated probability that at least two of the puppies will be
female, [tex]P(e)=\frac{n(e)}{n(s)}[/tex]
⇒ [tex]P(e)=\frac{6}{10}[/tex]
⇒ [tex]P(e)=0.6[/tex]
Thus the percentage of the female puppies = [tex](0.6)(100)[/tex]
⇒ [tex]60\%[/tex]
Hence we can conclude that the estimated probability that at least two of the puppies will be female is 60%.

which equation represents the linear function that is shown on the graph
Answers
Answer:
Y = (1/2)x - 2
Step-by-step explanation:
To compose a linear equation, always use the form
Y = Mx + C where C is the y-intercept and M is the gradient.
In this case, pick any 2 points on the graph to solve for M
e.g (8,2) and (6,1)
Gradient = (2 - 1) /(8 -6) given by (y1 - y2) / (x1 - x2) = 1 / 2
Substitute into the form, we get
Y = (1/2)x + C
Now, we use any point again on the graph,
e.g (6,1) and substitute as (x, y) into the above function.
We will get 1 = (6)(0.5) + C
C = -2
Piece them up and u get the full function.

Since it is a positive value, we need to change it into a negative value in order for it to be opposite (perpendicular). So that will be -3.
Now we have to flip it. There is a 1 under that -3, it’s just not necessarily shown. So you flip it upside down and that will be -1/3.
-3/1 —> -1/3
