PLEASE HELP ASAP, THANK YOU!
Answer:
Option (1)
Step-by-step explanation:
Exponential equation that models the increase in the number of books has been given as,
[tex]B=8700e^{0.04t}[/tex]
Here, B = Number of books
t = Number of years
Number of books after t = 3,
[tex]B=8700\times e^{0.04\times 3}[/tex]
[tex]=8700\times e^{0.12}[/tex]
= 9809.226
≈ 9809
Therefore, Option (1) will be the correct option.
Answer:
After 3 years, the library will have approximately 9,809 books.
Step-by-step explanation:
If [tex]t[/tex] represents the number of years passed, in the time of 3 years, the library shall have [tex]8700e^{0.04*3} = 8700e^{0.12}[/tex] ≈ [tex]8700*1.12749[/tex] ≈ [tex]9,809[/tex] books.

Terrell got 1 3/4 pounds of ground meat and 2 1/6 of ground chicken. he used 1 2/3 pounds of ground chicken to make a casserole. how much ground chicken did he have left?
Answer:
Okay so we have to solve this in separate parts. Like so, its wiill go like this: 2+ 1/6 - 1 - 2/3. So we see that we have 2 and 1 as whole. Subtract 2 - 1 is 1 right. Now for fractional part 1/6 - 2/3. Since its uneven, we have to find the LCD which is 6. This forms of our fractions into 1/6- 4/6. 1/6 - 4/6 is 3/6. simplify it would result in 1/2. The amount of ground chicken that Terrell has left is 1/2.

Graph the triangle with vertices (8,8), (0,3), and (9,2).
there are 650 students in a school if the number of girls is 106 more than the boys how many boys are in the school
Answer:
boys = 272
Step-by-step explanation:
b = boys
g = girls
1) write two equations with the given informations:
g + b = 650
g = b + 106
2) substitute the value of g in the first equation:
b + 106 + b = 650
3) solve the equation for b
2b = 544
b = 272
4) substitute the value in the second equation
g = 272 + 106
g = 378
girls = 378
boys = 272

!! i don’t understand:(!!Frank estimated the height of his office building to be 35 ft. The actual height of his office building is 33 ft.
Find the absolute error and the percent error of Frank's estimate. If necessary, round your answers to the nearest tenth
absolute error : _ ft
percent error : _ %
Answer:
See explaination and answer below
Step-by-step explanation:
Absolute Error:
ae = | E - A |
ae = | 35ft - 33ft|
ae = 2 ft
Percent Error:
pe = 100% * | E - A | / A
pe = 100% * | 35ft - 33ft | / 33ft
pe = 6.06% error
EDIT: 6.1% if asked to the nearest tenth.

Select all the shapes that do not have perpendicular sides.
A. Square
B. Equilateral triangle
C. Rectangle
D. Right triangle
E. Acute triangle
Answer:
B and E
Step-by-step explanation:
perpendicular sides mean they will equal 90 degrees... so all rectangles and squares are perpendicular- a 90 degree triangle also is perpendicular. The Equatorial and the Acute triangle do not have 90 degree angles

Individual taxi fares in Metro City are normally distributed with a population mean equals to $10 and a population standard deviation of $4. Assume drawing from an infinite population, a random sample of 64 fares is obtained. Based on these information, what is the probability that the sample mean fare of the 64 fares in the sample is between $9.5 and $10
Answer:
0.3413 = 34.13% probability that the sample mean fare of the 64 fares in the sample is between $9.5 and $10.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean equals to $10 and a population standard deviation of $4
This means that [tex]\mu = 10, \sigma = 4[/tex]
Sample of 64
This means that [tex]n = 8, s = \frac{4}{\sqrt{64}} = 0.5[/tex]
What is the probability that the sample mean fare of the 64 fares in the sample is between $9.5 and $10?
This is the pvalue of Z when X = 10 subtracted by the pvalue of Z when X = 9.5.
X = 10
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{10 - 10}{0.5}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a pvalue of 0.5
X = 9.5
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{9.5 - 10}{0.5}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a pvalue of 0.1587
0.5 - 0.1587 = 0.3413
0.3413 = 34.13% probability that the sample mean fare of the 64 fares in the sample is between $9.5 and $10.
On the grid draw the graph of x + 2y =7
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]x + 2y = 7[/tex]
Required
Draw the graph
First, we identify at least 2 possible values of x and y
Let [tex]x = 1[/tex]
Solve for y
[tex]x + 2y = 7[/tex]
[tex]1 + 2y = 7[/tex]
[tex]2y = 6[/tex]
[tex]y = 3[/tex]
So, a point is: [tex](1,3)[/tex]
Let [tex]x = 3[/tex]
Solve for y
[tex]x + 2y = 7[/tex]
[tex]3 + 2y = 7[/tex]
[tex]2y = 7 -3[/tex]
[tex]2y = 4[/tex]
[tex]y = 2[/tex]
So, another point is: [tex](3,2)[/tex]
Plot [tex](1,3)[/tex] and [tex](3,2)[/tex] on the graph, then draw a straight line through both points

Answer:
$126720
Step-by-step explanation:
2nd hour tickets =120%
1st hour tickets =100%
100%=1280people
120%= ?
=1536 people+1280
=2816people were sold tickets
2816people are the same as 2816tickets
If 1 ticket =$45
2816tickets=?

a 50.2°
b. 56.4°
C 39.8
d. 33.6°
ANSWER:C

39.80°
Step-by-step explanation:
Find the diagram attached
Given the following
Opposite side = 5m
Adjacent = 6m
