Answer: 11.5
Step-by-step explanation:
To find the mean first add all the numbers then divide by the amount of numbers you added.
10 + 11 + 12 + 12 + 11 + 13 = 69
69/6 = 11.5
Answer:
[tex]mean=11.5[/tex]
Step-by-step explanation:
By definition the Mean is the average of a set of numbers.
In this case, we know that the ages in years of children on the swim team are the following:
10, 11, 12, 12, 11, and 13
Then, to calculate themean age of a child on the swim team, we need to add up all the numbers and divide this by the total number of values in the set.
You can observe that there are six values. Then, the mean age of a child on the swim team is:
[tex]mean=11.5[/tex]
an expression is shown. 5x=32 what is the value of x that makes the equation true.
Answer:
6.4
Step-by-step explanation:
5x = 32
Divide both sides by 5.
5x/5 = 32/5
x = 6.4
Divide by 5 on both sides.
5x divided by 5 leaves x alone.
32 divided by 5 is 6.4.
6.4 • 5 = 32
X = 6.4

2. MONEY Hans opens a savings account by depositing
$1200. The account earns 3 percent interest
compounded weekly. How much will be in the
account in 10 years if he makes no more deposits?
Assume that there are exactly 52 weeks in a year and
round your answer to the nearest cent.
Using the formula for compound interest, the total amount in the account after 10 years, with no further deposits and 3 percent interest compounded weekly, is approximately $1615.65.
Explanation:This problem involves the concept of compound interest, specifically interest compounded weekly. To calculate the total amount in the account after 10 years, the formula for compound interest is used, which is A = P(1 + r/n)^(nt).
In this case, P, the principal amount, is $1200. The annual interest rate, r, is 3% or 0.03 when converted into decimal form. The number of times interest is compounded per year, n, is 52 weeks since interest is compounded weekly. Lastly, t stands for the number of years the money is invested or borrowed for, which is 10 in this instance. Plug these values into the formula to get the total amount after 10 years.
A = 1200(1 + 0.03/52)^(52*10) = $1615.65
So, if Hans makes no further deposits and the account earns 3 percent interest compounded weekly, the amount in the account after 10 years will be approximately $1615.65.

Matilda measures the perimeter of her bedroom to determine how many feet of border she needs to go around the tops of the walls. Two walls are each 96 inches long, and two walls are each 3 yards long. She pays $30 for border that costs $1 per foot. What are steps that you should take to determine if Matilda bought the correct amount of border? Select all that apply.
Answer:
She did not buy enough border. She needs 34 ft not 30.
Step-by-step explanation:
Find the perimeter of her room in feet:
12 inches in a foot
96/12=8
3 feet in a yard
3(3)=9
8 ft + 8 ft + 9 ft + 9 ft = 34 ft
She bought 30 ft of border, which is not enough because she needs 34 ft
The given border of 30 feet is not enough.
What is Perimeter?A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter.
Given:
Two walls are each 96 inches long, and two walls are each 3 yards long.
She pays $30 for border that costs $1 per foot.
First step is to convert inches to feet
1 inch = 1/12 feet
96 / 12 = 8 feet
and, 1 yard = 3 feet
3 x 3 = 9 feet
Now, the perimeter of the room
= 9 + 9 + 8 + 8
= 34 inches
The feet of border bought
= $30 / $1
= 30
So, 34 > 30 thus the border is not enough

Answer: first option
Step-by-step explanation:
You can observe in the figure that the total budget is $1,695.00 and the car is $272.00
Then, you know that the total budget represents the 100%, then, to calculate what percent of the total budget the car is, you need to divide $272.00 by $1,695.00 and multiply this by 100:
[tex]\%car=\frac{ \$272.00}{ \$1,695.00}*100\\\\\%car=16.04\%[/tex]
Rounded to the nearest tenth:
[tex]\%car=16.0\%[/tex]
Answer:
16%
Step-by-step explanation:
We have been given a table for the budget of June month.
Using that table we need to calculate about what percent of the total budget is the car. Then round the answer to the nearest tenth.
From table we see that budget for the car = $272
From table we see that total budget for June month = $1695
then required percent is given by formula :
[tex]percent=\frac{part}{whole}\cdot 100\%[/tex]
[tex]percent=\frac{272}{1695}\cdot 100\%[/tex]
[tex]percent=\frac{27200}{1695} \%[/tex]

Here we are going to use the rule which says that
i) equal arc segments subtends equal angles at the circle
ii) The Angle subtended by any arc segment at center is double to that of the angle subtended by the same arc at its circumference.
For more details please refer to the image attached to this problem.
Let us say that the angle subtended by arc mAB at center O = 6∅
Hence , ∠AOB=6∅
Hence ∠ADB = 3∅ ( Rule ii as discussed above )
Also as length of arc mCD = x , the angle subtended by it on the center will be in the same ratio as it was subtended by arc with length 6x
Hence
∠COD=∅
Hence
∠CAD=∅/2
Hence in ΔATD
∠ATD + ∠ADT +∠DAT = 180°
∠ATD + 3∅+∅/2= 180°
∠ATD = 180° - (3∅+∅/2) ----------(A)
Also
∠ATD + ∠ATB = 180°
From (A)
180° - (3∅+∅/2) +∠ATB = 180°
∠ATB = (3∅+∅/2)
∠ATB = (6∅+∅)/2
∠ATB = (7∅)/2
However , in order to find the exact value of∠ATB we need to evaluate ∅, and to find it , we must have some value of x .

Find the slope and the y-intercept of the line Y= 7X -6
Answer:
Slope: 7
y-intercept:-6
Step-by-step explanation:
The equation of the line in Slope-intercept form is the following:
[tex]y=mx+b[/tex]
Where "m" is the slope of the line and "b" is the y-intercept.
You have the equation of the given line:
[tex]y=7x-6[/tex]
You can observe that it is written in Slope-intercept form, therefore, you can identify that the slope and the y-intercept are the following:
[tex]m=7\\b=-6[/tex]
A. The slope is 7.
B. The line rises steeply right 7 units for every 1 unit increase in x.
Here's how to find the slope and y-intercept directly from the equation:
Understanding the Slope-Intercept Form:
The equation of a line can be written in *slope-intercept form* as `y = mx + b`, where:
`m` represents the slope of the line.
`b` represents the y-intercept, which is the point where the line crosses the y-axis.
Identifying Slope and Y-Intercept:
In the given equation, `y = 7x - 6`, we can directly identify the values:
The slope `m` is the coefficient of `x`, which is 7.
The y-intercept `b` is the constant term, which is -6.
Interpreting the Slope:
A slope of 7 indicates that for every 1 unit increase in `x`, the `y` value increases by 7 units. This means the line rises steeply from left to right.
Question:
Find the slope and y-intercept of the line whose equation is y= 7x-6.
What is the slope? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. The slope is ______ (Type an integer or a fraction.)
B. The slope is undefined.
