B. First term = 5, Common difference = -3

Step-by-step explanation:

The first term is f(1) = 8 - 3(1) = 8 - 3 = 5.

The common difference is the coefficient of  n.  Another way to see this is to compute the second term, f(2) = 8 - 3(2) = 8 - 6 = 2.  The second term is 3 less than the first.  The common difference is -3.

The sequence goes 5, 2, -1, -4, ...

Hmm I think the answer is 95%
1 standard deviation is 13
To find out the range of scores that fit 1 standard deviation from the mean, you would have to take away and add 13 from the mean (133) this gives a range of 120-146 which isn’t right because you’re looking for 107-159.
Next, look for 2 standard deviations from the mean which is just 13 x 2=26.
To find the range of scores that are 2 standard deviations from the mean take away and add 26 to the mean (133) which gives a range of 107-159. This is the correct answer.
2 standard deviations represents 95% of the data. That’s why I think the answer is 95%.

The circus admits children for $2 each and adults for $5 each. How many of each ticket were sold if 160 total tickets were sold for $476?

Answers

Basically you solve this by elimination or substitution
So you first make an equation where
c represents numbers of children tickets and ‘a’ represents adult tickets
a+c= 160
2a+ 5c=476


Multiply first equation by -2 to cancel out the a after addition
-2a-2c =-320
When you add the above equation with 2a +5c=476 you get 3c=156 which means that c=52 so the number of children tickets sold = 52
Now you substitute this answer to any of the equations and work out the value of a
a+52=160
a= 108

What is an equation?

The term "equation" refers to a pair of algebraic expressions with the same value and the sign "=" in between.

We have an equation,

221 = x + 68

x = 221 - 68

x = 153

In 153,

1 is in place of hundred 100, 5 is in the place of 10 so, 50.

Therefore, x = 53 is the amount that needs to be to balance the scale.

John is putting a fence around his garden that is shaped like a half circle and a rectangle.How much fencing will John need? Use for .32 ft39 ft46 ft57 ft

Answers

Answer:

The perimeter of the garden = 46 ft

Step-by-step explanation:

The exact question is as follows :

Given - John is putting a fence around his garden that is shaped like a half circle and a rectangle.

A rectangle has a length of 14 feet and width of 7 feet. A semicircle with diameter of 7 feet is on top of the rectangle.

To find - How much fencing will John need? Use  22 over 7 for Pi.

A. 32 ft

B. 39 ft

C. 46 ft

D. 57 ft

Solution -

The figure is as follows :

The perimeter of the garden is equal to sum three sides of the rectangle plus the circumference of a semicircle

Now,

Given that,

Length of Rectangle = 14 feet

Breadth of Rectangle = 7 feet

Now,

Sum of three sides of Rectangle = 14 + 14 + 7

                                                    = 35

Now,

Circumference of Semicircle = (1/2)[tex]\pi[/tex] D where D is the diameter

So,

Circumference of Semicircle = (1/2)(22/7)(7)

                                                = 11

⇒Circumference of Semicircle = 11

So,

The perimeter of the garden = 35 + 11

                                                = 46 ft

⇒The perimeter of the garden = 46 ft

81, Option 2.

Step-by-step explanation:

[tex]3^{4}[/tex] means 3 x 3 x 3 x 3, that is 3 multiplied 4 times with itself.

4y = 7+3x
Pizz help mee

Answers

Answer:

(3,4) is the solution of both equations.

Step-by-step explanation:

The given equations are :

3x – 2y = 1 ....(1)

4y = 7+3x

4y-3x = 7 .....(2)

Put x = 3 and y = 4 in equation (1).

3(3) – 2(4) = 9-8

= 1

So, (3,4) is the solution of the equation (1).

Again put x = 3 and y = 4 in equation (2).

4(4)-3(3) = 16-9

= 7

Hence, (3,4) is the solution of both equations.
