Answer:
C. 3.5
Step-by-step explanation:
To find the mean you add up the numbers, which would be 21. And then, divide 21 by how many number you added, so you added together 6 numbers, so divide 21 by 6, which you would get 3.5. I hope this helps :)

Solve the equation by completing the square. 0=x^2-14x+46 A. B. C. D.
Answer:
x = 16
Step-by-step explanation:
0=x^2-14x+46 is to be solved for x by completing the square. The first two terms, x^2 and -14x, are the incomplete square. We must find a term to add to, and then subtract from x^2 - 14x, so that we have a perfects square on the left and a negative number on the right:
x^2 - 14x = x^2 - 14x + (half of -14)^2 - (half of -14)^2 results in transformation of the original 0=x^2-14x+46 to
x^2 - 14x + 49 - 49 + 46 = 0, which simplifies to:
(x - 7)^2 - 3 = 0. We want to solve this for x.
To do that, rewrite (x - 7)^2 - 3 = 0 as (x - 7)^2 = 3, and then square both sides. We get:
x - 7 = 9, or x = 16

1. A ladder that is 10 feet long is leaning against a wall at a 71° angle.
a. How far from the wall is the foot of the ladder?
b. How high up the wall does the ladder reach?
Answer:
cosine 71° = distance from wall / 10
A) distance from wall = cosine (71) *10
distance from wall = 3.2557 feet
B) Height up the wall ^2 = 10^2 - 3.2557^2
Height up the wall ^2 = 100 -10.59958
Height up the wall ^2 = 89.40041751
Height up the wall = 9.45518 feet

Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil. Jason decides to
test the land for oil. He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. What is the probability that the land has NO OIL and the test shows that there is NO OIL ?
A) 0
B) 0.09
C) 0.11
D) 0.44
Answer:
0.09
Step-by-step explanation:
.45 x .20 = .09
theres a 45% chance of there being oil and theres a 20% chance the test is inaccurate( just do 100-80 to get that).
Suppose there is a 1.9°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 48.8°F, what will be the temperature when the plane reaches an altitude of 8,000 ft?
Answer:
33.6 degrees F
Step-by-step explanation:
8000/1000 = 8
8(1.9) = 15.2 degree drop
48.8 - 15.2 = 33.6 degrees F

last year hari was 4 feet tall, and this year he is 5 feet tall. what is the percent increase of his height?
Answer:
75%
Step-by-step explanation:
hsjdidjdbdkosksksldmenk
Last year Hari was 4 feet tall, and this year he is 5 feet tall. There is a 25% increase in his height in one year.
What is a percent in math?Percent, a relative value indicating the hundredth part of any amount. One percent (symbolized 1%) is the hundredth part; for that reason, 100 percent represents everything and 200 percent specifies two times the given amount.
Conclusion: The percentage can be calculated by dividing the value by the total value and then multiplying the result by 100. The formula used to calculate the percentage is: (value/total value)×100%.
let 4feet be 100% of his height.
4 - 100%
x% = (increased height/actual height) * 100
x% = (5/4) * 100
x% q= 125
percent increase of height = 125-100 = 25

The number that is a term in both the sequence f(n)=f(n-1)+5 and the sequence f(n)=3(2)^n-1 is 48.
What is the solution of the function?The solution of the given function is determined by substituting the values of f(n).
The sequences are:
f(n)=f(n-1)+5
F(1) = 3

Please help me someone
Jillian lands the beanbag in the hole in about half of her attempts in a beanbag toss game. How can she predict the number of times she will get the beanbag in the hole in her next 5 attempts using a coin toss?
Step-by-step explanation:
So in the case of Jillian, landing the beanbag in the cornhole is 1/2. So this is just like flipping a coin.
the first time she tosses the beanbag she has a 1/2 chance of getting it in the cornhole and 1/2 chance of getting it outside the cornhole. And since she needs to get 5 tosses in a row into the cornhole, we multiply
1/2(1/2)(1/2)(1/2)(1/2)=1/32

The red thing at the top is a right angle. Find the missing side lengths and leave answers as radicals in simplest form ILL GIVE BRAINLIEST
Answer:
A. x = 13
y = (13√3)/3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = (26√3)/3
Adjacent = x
Opposite = y
✔️Apply CAH to find x:
Cos 30 = Adj/Hyp
Cos 30 = x/(26√3)/3
√3/2 = x*3/(26√3) (cos 30 = √3/2)
√3/2 = 3x/(26√3)
Cross multiply
2*3x = (26√3)*(√3)
6x = 26*3
6x = 78
x = 78/6
x = 13
✔️Apply SOH to find y:
Sin 30 = Opp/Hyp
Sin 30 = y/(26√3)/3
Sin 30 = y*3/(26√3)
½ = 3y/(26√3) (sin 30 = ½)
Cross multiply
2*3y = (26√3)*1
6y = 26√3
Divide both sides by 6
y = (26√3)/6
y = (13√3)/3
Constant of proportionality of x=9 and y=4
