Find a so that the point (-1,4) is on the graph of f(x) = ax^2+1

Answer:

76

38

114

Step-by-step explanation:

50% of 152

= ( 50 / 100 ) x 152

= ( 1 / 2 ) x 152

= 152 / 2

= 76

25% of 152

= ( 25 / 100 ) x 152

= ( 1 / 4 ) x 152

= 152 / 4

= 38

75% of 152

= ( 75 / 100 ) x 152

= ( 3 / 4 ) x 152

= ( 3 x 152 ) / 4

= 3 x 38

= 114

Answer:

40 children went on the cruise.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of adults on the cruise

y is the number of children on the cruise.

57 tickets were sold:

This means that [tex]x + y = 57[/tex], and since we want the number of children y, [tex]x = 57 - y[/tex]

Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.

This means that:

[tex]22x + 10y = 774[/tex]

Since [tex]x = 57 - y[/tex]

[tex]22(57 - y) + 10y = 774[/tex]

[tex]1254 - 22y + 10y = 774[/tex]

[tex]12y = 480[/tex]

[tex]y = \frac{480}{12}[/tex]

[tex]y = 40[/tex]

40 children went on the cruise.

Repent while there’s still time. Love while you still can. Give till there’s nothing left. Serve with all you’ve got. Go while you’re still able. Share all that you have. Follow hard after God. Live with no regrets. Time is of the essence. If we only have today, there’s still time. Don’t miss this time. Look yourself in the mirror and ask your self - If I died today, would the Lord judge me worthy of eternal life? If the answer is no, then ask him for forgivness. As long as you are really sorry, he will forgive you. If you want to talk, I am here. If you need time alone, then I will leave you alone. If you need a Bible, I can get you one. Follow your heart and never stop doing good. Thank you for reading this, and have a great day. May the good Lord bless you, your family, and the world.

Answer:

V = 286319.465 cm3

Step-by-step explanation:

First, you have to find the radius to be able to find the volume of a sphere.

The equation for the area of a circle is pi r^2 so you have to so some algebra.

5252 = pi r ^2

5252/pi = r^2

1671.76352 = r^2

sqrt(1671.76352) = r

r = 40.8872048

then you do the equation for the volume of a circle which is 4/3 pi r^3

4/3 pi (40.8872048)^3

4/3 pi 68353.7373

4/3 214739.599

286319.465

V = 286319.465 cm3

Answer:

F- test

Step-by-step explanation:

Testing the hypothesis about the equality of  k (k>2) population means

Test statistic F is used to find the whether there is no difference in the average age of each group.

Test statistic to be used

F= Between Mean Square/ Within Mean Square

F= s1²/s2²   where s1 and s2 are  independent unbiased estimates of the variance and their values do not differ greatly.

Which have  v1= k-1 and v2= n-k degrees  of freedom

The analysis of variance F -t est is always a one tailed test with rejection region located in the right tail of the F- distribution.

Answer:

x = 9

Step-by-step explanation:

We need to find the value of x if the polygons in each pair are similar.

As they are similar, the ratio of their sides are equal.

The sides of first polygon are 6,12 and 4.8. On the other hand, the sides of second polygon are (2x-9) and 18.

So,

[tex]\dfrac{6}{2x-9}=\dfrac{12}{18}\\\\\dfrac{6}{2x-9}=\dfrac{2}{3}\\\\\dfrac{3}{2x-9}=\dfrac{1}{3}\\\\x=9[/tex]

So, the value of x  is equal to 9.

Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.

A circumference gives the length around a circular object, it is the perimeter used for the circular objects.

Given that a circular tablecloth has a radius of 24 inches, we need to find the length around it,

So, the length around a circular object is its circumference,

We know that circumference of the circular object = π × diameter,

Diameter = 2 × radius = 48 inches.

So, the length around the circular cloth = π × 48

= 3.14 × 48
= 150.72

Hence Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.
