Answer:
Height: 6.7 Length: 22
Step-by-step explanation:
Use Soh (sin(angle)=[tex]\frac{opposite}{hypotenuse}[/tex]) Cah (cos(angle)=[tex]\frac{adjacent}{hypotenuse}[/tex]) Toa (tan(angle)=[tex]\frac{opposite}{adjacent}[/tex])
Height:
You'd use sin so the equation is sin17=x/23 which is equal to (rounded) 6.7
Length:
You'd use cos so the equation is cos17=y/23 which is equal to (rounded) 22
*You always need to use a calculator when using sin, cos, and tan*
*SohCahToa is an easy way to remember the equations!*

5x-8y=29 find y when x= -1
Answers
Answer:
-4.25
Step-by-step explanation:
When x = -1, the equation is 5(-1) - 8y = 29. This simplifies to -5 - 8y = 29. Add 5 to both sides to get -8y = 34. Divide -8 from both sides to get y = -4.25.

Last year, Greg got a new job managing the gift shop at the Bern Valley Zoo. One of his responsibilities was to track the shop's total sales each day. This box plot shows the results. Gift shop sales ($) 200 250 300 350 400 450 What percent of the time did the gift shop have sales of $350 or less? %
Answers
Answer:
Step-by-step explanation:
There were 4 days when sales were 350 or less out of 6 days so
100(4/6)=400/6=[tex]66\frac{2}{3}\% $ or rounded to 66.67% $ [/tex]
The percentage of the time did the gift shop have sales of $350 or less should be considered as the 66.67%.
Calculation of the percentage:Sinceas we can see that there are total 6 things out of which 4 should be within 350 or less than 350
So here the percentage be like
[tex]= 4\div 6[/tex]
= 66.67%
Hence, The percentage of the time did the gift shop have sales of $350 or less should be considered as the 66.67%.

Find the value of x y and m
Answers
Answer:
x = 33
y = 66
m<BGK = 71°
Step-by-step explanation:
✔️(2x + 5) + (3x + 10) = 180° (consecutive interior angles)
Solve for x
2x + 5 + 3x + 10 = 180
Add like terms
5x + 15 = 180
5x = 180 - 15 (subtraction property of equality)
5x = 165
Divide both sides by 5
x = 33
✔️(2x + 5) = (y + 5) (alternate interior angles are congruent)
Plug in the value of x
2(33) + 5 = y + 5
66 + 5 = y + 5
71 = y + 5
71 - 5 = y
66 = y
y = 66
✔️m<BGK = (y + 5) (vertical angles)
Plug in the value of y
m<BGK = (66 + 5)
m<BGK = 71°

The number of typos made by a student follows Poisson distribution with the rate of 1.5 typos per page. Assume that the numbers of typos on different pages are independent. (a) Find the probability that there are at most 2 typos on a page. (b) Find the probability that there are exactly 10 typos in a 5-page paper. (c) Find the probability that there are exactly 2 typos on each page in a 5-page paper. (d) Find the probability that there is at least one page with no typos in a 5-page paper. (e) Find the probability that there are exactly two pages with no typos in a 5-page paper.
Answers
Answer:
a) 0.8088 = 80.88% probability that there are at most 2 typos on a page.
b) 0.0858 = 8.58% probability that there are exactly 10 typos in a 5-page paper.
c) 0.001 = 0.1% probability that there are exactly 2 typos on each page in a 5-page paper.
d) 0.717 = 71.7% probability that there is at least one page with no typos in a 5-page paper.
e) 0.2334 = 23.34% probability that there are exactly two pages with no typos in a 5-page paper.
Step-by-step explanation:
Poisson distribution:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
Binomial distribution:
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The number of typos made by a student follows Poisson distribution with the rate of 1.5 typos per page.
This means that [tex]\mu = 1.5n[/tex], in which n is the number of pages.
(a) Find the probability that there are at most 2 typos on a page.
One page, which means that [tex]\mu = 1.5[/tex]
This is
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
In which
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-1.5}*(1.5)^{0}}{(0)!} = 0.2231[/tex]
[tex]P(X = 1) = \frac{e^{-1.5}*(1.5)^{1}}{(1)!} = 0.3347[/tex]
[tex]P(X = 2) = \frac{e^{-1.5}*(1.5)^{2}}{(2)!} = 0.2510[/tex]
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.2231 + 0.3347 + 0.2510 = 0.8088[/tex]
0.8088 = 80.88% probability that there are at most 2 typos on a page.
(b) Find the probability that there are exactly 10 typos in a 5-page paper.
5 pages, which means that [tex]n = 5, \mu = 5(1.5) = 7.5[/tex].
This is P(X = 10). So
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 10) = \frac{e^{-7.5}*(7.5)^{10}}{(10)!} = 0.0858[/tex]
0.0858 = 8.58% probability that there are exactly 10 typos in a 5-page paper.
(c) Find the probability that there are exactly 2 typos on each page in a 5-page paper.
Two typos on a page: 0.2510 probability.
Two typos on each of the 5 pages: (0.251)^5 = 0.001
0.001 = 0.1% probability that there are exactly 2 typos on each page in a 5-page paper.
(d) Find the probability that there is at least one page with no typos in a 5-page paper.
0.2231 probability that a page has no typo, so 1 - 0.2231 = 0.7769 probability that there is at least one typo in a page.
(0.7769)^5 = 0.283 probability that every page has at least one typo.
1 - 0.283 = 0.717 probability that there is at least one page with no typos in a 5-page paper.
(e) Find the probability that there are exactly two pages with no typos in a 5-page paper.
Here, we use the binomial distribution.
0.2231 probability that a page has no typo, so [tex]p = 0.02231[/tex]
5 pages, so [tex]n = 5[/tex]
We want P(X = 2). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{5,2}.(0.2231)^{2}.(0.7769)^{3} = 0.2334[/tex]
0.2334 = 23.34% probability that there are exactly two pages with no typos in a 5-page paper.

The figure has an area of 42 yd? Which equation can be
used to find the value of x?
A 13x + 1 = 42
B 14x = 42
C 15x -1 = 42
D 16x=42
Answers
Answer:
B. 14x = 42
Step-by-step explanation:
The figure is composed of a rectangle and a trapezium
(L*W) + [½(a + b)h] = Area of the figure
Where,
Area = 42
L = 2x
W = 3
a = 3 + 4 = 7
b = 9
h = x
Plug in the values
(2x*3) + [½(7 + 9)x] = 42
6x + [½(16x)] = 42
6x + 8x = 42
14x = 42
