Answer:
KRM = 44 degrees, MRD = 46 degrees
Step-by-step explanation:
This angle is a right angle so it equals 90 degrees. That means that equations 3g + 29 and 7g + 11 will amount to 90 degrees.
(3g + 29) + (7g + 11) = 90
Combine like terms:
10g + 40 = 90
10g = 50
g = 5
Plug in 5 to both equals (in this case the question only asks for 3g + 29 or KRM):
3(5) + 29 =
15 + 29 =
44 =
7(5) + 11 =
35 + 11 =

Answer: D) The value of [tex]\sqrt{215}[/tex] is between 14.5 and 15
Step-by-step explanation:
Let's start by taking the squaring these numbers.
[tex]13^2=169\\13.5^2=182.25\\14^2=196\\14.5^2=210.25\\15^2=225[/tex]
215 is in between 14.5 squared and 15 squared. That means its square root will be between 14.5 and 15.5

Jeff is standing on the 10 m diving platform. His coach is on the ground to the left of him, while his parents are on the ground to the right of him. His coach is looking at him at an angle of 37 degrees with the ground, while his parents are looking at him at an angle of 32 degrees with the ground. If the angle at the base of the platform between Jeff’s coach and Jeff’s parents is 100 degrees, how far apart are his coach and his parents to the nearest meter?
Answer:
29 m
Step-by-step explanation:
Since Jeff's coach is at the left of the platform and the platform at an angle of elevation of 37° and Jeff's parent's are on the right of the platform with the platform at an angle of elevation of 32°. The line of sight of Jeff's coach, the distance between Jeff's coach and parents and the line of sight of Jeff's parents form a triangle.
Since the platform is 10 m high, it is a perpendicular to the base of the triangle.
This perpendicular bisects the original triangle into two right angled triangles - one on the left and one on the right - with base angle 37° and 32° respectively.
Using trigonometric ratios with the opposite side to each angle the height of the platform from the ground (10 m) and the opposite angles 37° and 32° respectively, then the length of each base is gotten from
tan37° = 10/L and tan32° = 10/L' where L and L' are the lengths of each base of the two right angled triangles respectively.
So, L = 10/tan37° = 10/0.7536 = 13.3 m and L' = 10/tan32° = 10/0.6249 = 16 m.
The length d = L + L' is the distance between Jeff's coach and Jeff's parents
So, d = L + L'
= 13.3 m + 16 m
= 29.3 m
≅ 29 m to the nearest meter.
Note that we do not need the third angle in the triangle which is 100° the angle of separation between Jeff's coach and Jeff's parents which is at the base of the platform.
Which are solutions of the equation x^2-16=0? Check all that apply.
Answer:
+4, -4
Step-by-step explanation:
There are only two solutions to this equation.
=> x^2 - 16 = 0
=> x^2 - 4^2 = 0
=> (x+4) (x-4) = 0 {According to a^2 - b^2 = (a+b) (a-b)}
=> x = 4, -4
Answer:
x = 4
x = - 4
Step-by-step explanation:
Method 1: Quadratic Formula
Ignore the A before the ±, it wouldn't let me type it correctly.
[tex]x=\frac{-b±\sqrt{b^{2} -4ac} }{2a}[/tex]
x² - 16 = 0
a = 1
b = 0
c = - 16
[tex]x=\frac{-(0)±\sqrt{0^{2} -4((1)(-16))} }{2(1)}[/tex]
[tex]x=\frac{0±\sqrt{0 -4((1)(-16))} }{2(1)}[/tex]
[tex]x=\frac{0±\sqrt{0 +64} }{2(1)}[/tex]
[tex]x=\frac{0±\sqrt{64} }{2}[/tex]
[tex]x=\frac{0±8 }{2}[/tex]
Two separate equations
One must have a + (positive) and the other will have a - (negative).
[tex]x=\frac{0+8 }{2}[/tex]
[tex]x=\frac{8 }{2}[/tex]
x = 8 ÷ 2
x = 4
[tex]x=\frac{-8 }{2}[/tex]
x = - 8 ÷ 2
x = - 4
Method 2: Factoring
x² - 16 = 0
(x - 4)(x + 4) = 0
Two separate equations
x - 4 = 0
x + 4 = 0
x - 4 = 0
x - 4 + 4 = 0 + 4
x = 4
x + 4 = 0
x + 4 - 4 = 0 - 4
x = - 4
Use a statistics calculator to find the area, in decimal form, rounded to four places after the decimal, under the (standard) Normal histogram and... (a) ...to the left of 1.8. (b) ...to the right of 2.4. (c) ...between 1.8 and 2.4.
Answer:
a) 0.9641.
b) 0.0082
c) 0.0277
Step-by-step explanation:
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.
(a) ...to the left of 1.8.
p-value of Z = 1.8, which, looking at the z-table, is of 0.9641.
(b) ...to the right of 2.4.
1 subtracted by the p-value of Z = 2.4.
Looking at the z-table, Z = 2.4 has a p-value of 0.9918.
1 - 0.9918 = 0.0082, which is the answer.
(c) ...between 1.8 and 2.4.
p-value of Z = 2.4 subtracted by the p-value of Z = 1.8.
From itens a and b, we have both. So
0.9918 - 0.9641 = 0.0277

The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 3408 miles, with a variance of 249,001. If he is correct, what is the probability that the mean of a sample of 36 cars would differ from the population mean by less than 198 miles
Answer:
[tex]0.98268[/tex]
Step-by-step explanation:
We are given that
Mean, [tex]\mu=3408[/tex]miles
Variance, [tex]\sigma^2=249001[/tex]
We have to find the probability that the mean of a sample of 36 cars would differ from the population mean by less than 198 miles.
n=36
[tex]P(|\bar{x}-3408}|<198)=P(3408-198<\bar{x}<198+3408)[/tex]
=[tex]P(3210<\bar{x}<3606)[/tex]
=[tex]P(\frac{3210-3408}{\sqrt{\frac{249001}{36}}}<\frac{\bar{x}-\mu}{\sqrt{\frac{variance}{n}}}<\frac{3606-3408}{\sqrt{\frac{249001}{36}}}[/tex]
[tex]=P(-2.38<Z<2.38)[/tex]
[tex]=P(Z<2.38)-P(Z<-2.38)[/tex]
[tex]=0.99134-0.00866[/tex]
=[tex]0.98268[/tex]
Hence, the probability that the mean of a sample of 36 cars would differ from the population mean by less than 198 miles=[tex]0.98268[/tex]

The average of any two consecutive even numbers in an even number. Find a counterexample.
Answer:
2 and 4
Step-by-step explanation:
2+4 = 6
6/2 = 3
average is sum of number divided by how many numbers there are.
A counterexample to the above rule of the average of two consecutive even numbers being even are 8 and 10.
A counterexample is one that disproves a logic.
The consecutive even numbers of 8 and 10 will give an average of:
= Sum of even numbers / 2
= (8 + 10) / 2
= 18 / 2
= 9
9 is not an even number so we can conclude that 8 and 10 are counterexamples to the above rule.
