Answer:
69.993
Step-by-step explanation:
Using the percentage error formula:
Percentage error = (true - measured value / true measurement ) * 100%
1% error in measurement
1% of 69.3
0.01 * 69.3 = 0.693
True measurement = error in measurement + measured value
True measurement = 0.693 + 69.3
Actual measurement = 69.993
Hence, actual measurement = 69.993.

Answer:
A)256stickers
B)8 stickers each
C)= 6 boxes
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION
Mrs. Kim bought 4 boxes of stickers at the store to share with her students. Each box contained64 stickers.
Part A
Enter the total number of stickers Mrs. Kim bought at the store.
(b)
Part B
Mrs. Kim wants to share the stickers equally with each of her students. There are 32 students in her class.
Enter the number of stickers that each student will get.
8 stickers each
(c)
Part C
How many more boxes of stickers does Mrs. Kim need if she wants each of her students to get 12 stickers? Enter the number below.
more boxes of stickers
A) 4× 64 stickers= 256stickers
B,) 256stickers/ 32 students
=8 stickers each
C)if she wants each of her students to get 12 stickers?
Let the total number of stickers = X
X/32 students = 12 stickers
X= 32 ×12
= 384 stickers
Number of boxes= 384 stickers/64 stickers
= 6 boxes
Here are 20 students in Jacob's homeroom. Five students bring their lunch to school. The rest eat lunch in the cafeteria. In simplest form, what fraction of students eat lunch in the cafeteria? By the way this is fraction do you know 2/3 like that you now Those types of fractions of students eat lunch in the cafeteria. What is the answer
Answer: 3/4
Step-by-step explanation:
Number of students in Jacob's homeroom = 20.
Number of students who bring their lunch to school = 5
Since the rest eat lunch in the cafeteria, the number of those who eats in the cafeteria will be:
= 20 - 5
= 15
Fraction that eats in the cafeteria will be: = 15/20 = 3/4

find the area of the triangle
The area of the triangle is:
[tex]\Large\displaystyle\text{$\begin{aligned}A\triangle &= \dfrac{21+7\sqrt{15}}{2}\\ \\A\triangle &\approx 24.055\\ \\\end{aligned}$}[/tex]
You can easily find the area of a triangle using the formula:
[tex]\Large\displaystyle\text{$\begin{aligned}A\triangle = \dfrac{bh}{2}\end{aligned}$}[/tex]
Where h is the height of the triangle, and b the base.
Looking at the figure we can see that h = 7, but we need to discover the base, we know that the base is:
[tex]\Large\displaystyle\text{$\begin{aligned}b = 3 + x\end{aligned}$}[/tex]
Where:
[tex]\Large\displaystyle\text{$\begin{aligned}8^2 &= x^2 + 7^2\\ \\x^2 &= 8^2 - 7^2 \\ \\x^2 &= 64 - 49\\ \\x^2 &= 15\\ \\x &= \sqrt{15}\end{aligned}$}[/tex]
Therefore, our base length is:
[tex]\Large\displaystyle\text{$\begin{aligned}b &= 3 + x\\ \\b &= 3 + \sqrt{15}\\ \\\end{aligned}$}[/tex]
Then we can just apply the formula for the area:
[tex]\Large\displaystyle\text{$\begin{aligned}A\triangle &= \dfrac{(3+\sqrt{15})\cdot 7}{2}\\ \\A\triangle &= \dfrac{21+7\sqrt{15}}{2}\\ \\A\triangle &\approx 24.055\\ \\\end{aligned}$}[/tex]

644
698
The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.
What is the expected value?In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.
The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces.
Then the probability of the oranges that weigh 5 ounces is given as,
p = 2/25
Then the number of oranges in the shipment can the manager predicts weigh 5 ounces will be given as,
E(x) = 700 x 2 / 25

represent? (5 points)
Part B: Write the equation for the line of best fit in the slope-intercept form and use
it to predict the number of matches that could be won after 13 months of practice.
Show your work and include the points used to calculate the slope. (5 points)
Answer:
It got cut off, but the approximate y intercept is 3 and slope intercept form is
y = x + 3 and I used the points 0,3 and 3,6 to calculate the slope using the slope equation y1 - y2/x1 - x2

Write 65/22 as a decimal. If necessary, use a bar to indicate which digit or group of digits repeats.
Answer:
2.954545454
Step-by-step explanation:
65/22 = 65 divided by 22. That is how many times 22 can go into 65
A decimal number has a decimal point in it. That is a whole number and some fraction that could be in tenths or otherwise.
65 is the numerator,
22 is the denominator
Using a calculator
65/22 = 2.9545454
Which of the following does not reveal the variation (spread) of the data?
O standard deviation
O the median
O the 5 number summary
O the range
O all of the above show spread
Answer:
Bru I’m in ur class and it’s The median
Step-by-step explanation:
It’s the median
Out of all the options listed, the only one that does not show variation (spread) is the median.
The median is simply used to show the medium value of a data set. It cannot be used to tell the variation because it does not take into account all the values but rather the middle one alone.
The other options are wrong because:
Standard deviation shows how spread out around the mean, variables are5 number summary gives a sense of the spread of the data because it takes into account several important variables in the data set The range shows the spread of the dataIn conclusion, only the median does not help with finding the variation of a dataset.

Answer: MN = 8.5
Step-by-step explanation:
Form it into a right triangle with MN being the hypotenuse (side opposite the right angle)
To make this a right triangle, plot a point at (8,-2) and connect the sides. The lengths of the legs that form the right angle are both 6 units. Use the Pythagorean theorem to solve for length of MN. a^2+b^2=c^2. (a and b are the legs that form the right angle and c is the hypotenuse)
6^2+6^2=c^2
36+36=c^2
72= c^2
8.48528137 = c.
Question says to round to nearest tenth of a unit
8.5 = c (line MN)

Answer:
Submarine submerges at the rate of =5m/min
descend starts from = 20m
submarine have to reach = -250m
Distance between above sea level to below sea level = 250 + 20 = 270m
time taken to reach 270 m = 270/5= 54 minutes

Bill mixes candy costing 45cents per pound with candy costing 65cents a pound. A 7-pound box of the mix costs $3.65. How much of each kind of candy should Bill use?
Answer:
Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.
Step-by-step explanation:
With the information provided, you can say that the sum of the pounds of each type of candy is equal to 7, which can be expressed as:
x+y=7
Also, the statement indicates the 7 pound box costs $3.65 and you can say that the sum of the results of multiplying the price of each candy for the number of pounds is equal to $3.65, which is:
0.45x+0.65y=3.65
You have the following equations:
x+y=7 (1)
0.45x+0.65y=3.65 (2)
Now, you have to solve for x in (1):
x=7-y (3)
Then, you have to replace (3) in (2):
0.45(7-y)+0.65y=3.65
3.15-0.45y+0.65y=3.65
0.20y=0.50
y=0.50/0.20
y=2.5
Finally, you can replace the value of y in (3) to find x:
x=7-y
x=7-2.5
x=4.5
According to this, the answer is that Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.
