Help please ill give brainy (7th grade math)

Answer:

10

Step-by-step explanation:

It is much easier to do this for one die. There is a 1/6 chance that a 3 occurs on a six-sided die. Another way to say that is that the expected number of 3’s that occur on a roll of a six sided die is 1/6. If we let X be 1 if a 3 occurs on the roll and 0.

Now, if the die is rolled 60 times, then we have 60 different values X1, X2,…,X60

Of course, this shouldn’t be all that surprising. After all, we threw the die 60 times, and there are 6 faces, so it seems reasonable that for a fair die, each face should come up about 10 times.

Answer:

Sample of the park. It is not all the people, just a few as a sample for their survey or project.

Answer:

1) if you use the graph, it should go in a straight line, if it does, it’s linear.

2) if you use a table, you can see to make sure the numbers go up/down at the same rate

3) if you have a graph and a table, you could always compare both, and make sure they’re both linear

Answer:

B

Step-by-step explanation:

The answer is b because ¼ can not go in to 2 ½ evenly (A), ¾ can not go into 2 ½ evenly either (c) so the only answer is B!

Answer:

{4, 13}

Step-by-step explanation:

Represent the integers by I and J.  Then I + J = -17 and I*J = 52.

Let's solve this system using substitution.  Solve the first equation for I as follows:  

I + J = -17 becomes I = -J - 17

Substitute -J -17 for   I   in the second equation:

(-J - 17)*J = 52

Performing the indicated multiplication, we get:

-J^2 - 17J - 52 = 0

Let's solve this using the quadratic formula.  The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is

(-17)^2 - 4(-1)(-52), or 289 - 208, or 81.  This result is positive, so we know that the quadratic equation has two real, unequal roots.  They are:

      17 ± √81         17 ± 9

J =  --------------- = ---------------

         2(-1)                  -2

Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and

J = (17 - 9)/2 = 8/2, or J = 4

Answer:

Since the shape was formerly a square,ofarea 100in²

Then,Area of square=side×side

100in²=side²

side=√100in²

side=10 inches

Perimeter of the shape=10+10+7+6+5

=38inches

Now a length of 3inches is cut off from the upper horizontal side and a length of 4in is also cut off from the right vertical side.

So now we can say a triangle of base 4in and height 3in is cut off from the square.

Area of cut off triangle=½base×height

=½×4×3=0.5×12

=6 inches ²

So the Area of the shape=Area of square-Area of triangle

=100-6=94inches²

Answer:

1. 36

2. 5390

Step-by-step explanation:

1. V=1wh/3

4 x 3 x 9 = 108

108/3 = 36

2. V=lwh/3

22 x 21 x 35 = 16170

16170/3 = 5390

1. Answer:

16,170

Step-by-step explanation:

Length times width times height

L = 21 m

W = 22 m

H = 35 m

32 m times 22 m times 21 m = 16,170

2. Answer:

Step-by-step explanation:

= 25 yards ; r = 25/2 = 12.5 yards

circumference of two semicircle = circumference of circle

= 2πr = 2*3.14*12.5 = 78.5 yards

Perimeter of school truck = 78.5 + 85 + 85 = 248.5 yards

Distance traveled by Jasmine = 3* 248.5 = 745.5 yards

Answer:

y=5(x-3)^2+2

Step-by-step explanation:

You plug the point into f(x)=a(x-3)^2+2... that already has already been solved for the vertex that you want. Then you swap it out for the solution you have solved for.

The required function is [tex]f(x)=5(x-3)^2+2[/tex].

Important information:

The vertex form of a quadratic function is:

[tex]f(x)=a(x-h)^2+k[/tex]

Where, [tex]a[/tex] is a constant and [tex](h,k)[/tex] is vertex.

Substitute [tex]h=3,k=2[/tex].

[tex]f(x)=a(x-3)^2+2[/tex]         ...(i)

The graph passes through the point (4,7). Substitute [tex]x=4, f(x)=7[/tex] in (i).

[tex]7=a(4-3)^2+2[/tex]

[tex]7=a+2[/tex]

[tex]7-2=a[/tex]

[tex]5=a[/tex]

Substitute [tex]a=5[/tex] in (i).

[tex]f(x)=5(x-3)^2+2[/tex]

Therefore, the required function is [tex]f(x)=5(x-3)^2+2[/tex].
