Answer:
Standardized z score = 2.06
His house rent is not an outlier
Step-by-step explanation:
The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier
We solve using z score formula
= z = (x-μ)/σ, where
x is the raw score = 1390
μ is the population mean = 970
σ is the population standard deviation = 204
His z score is calculated as:
z = 1390 - 970/204
z = 2.06
No his house rent is not an outlier
Brenda had bowling scores of 92, 110, 85, 78, and 96. She completed the steps below to determine the score she needs in her next game to have a mean, or average, bowling score of 96. Step 1: Find the total points needed to score in six games: 96 times 6 = 576. Step 2: Find the total points scored: 92 + 110 + 85 + 78 = 365. Step 3: Subtract the total points scored from the total points needed: 576 minus 365 = 211. Step 4: State the answer: Brenda needs to score 211 in her next game. Where did Brenda make her first mistake? Step 1 Step 2 Step 3 Step 4 Mark this and return
Answer:
Step 2
Step-by-step explanation:
Step 1: Find the total points needed to score in six games: 96 times 6 = 576.
Step 2: Find the total points scored: 92 + 110 + 85 + 78 = 365.
WRONG
Step 1: Find the total points needed to score in six games: 96 times 6 = 576.
Step 2: Find the total points scored: 92 + 110 + 85 + 78 + 96 = 461
Step 3: Subtract the total points scored from the total points needed: 576 minus 461 = 115
Step 4: State the answer: Brenda needs to score 115 in her next game.
Therefore,
Brenda make her first mistake in step 2

An alligator can eat 18 pounds of meat in 2 hours. If it continues eating at this same rate, how much can it eat in 7 hours?
Answer:
63 pounds
Step-by-step explanation:
Given data
Quantity of meat= 18 pounds
TIme taken= 2 hours
Rate= Quantity/Time taken
Rate= 18/2
Rate= 9 pounds per hour
Now time= 7 hours
Rate= 9 pounds per hour
Quantity= Rate*Time
Quantity= 9*7
Quantity= 63 pounds
Simplify the left side of equation so it looks like the right side. cos(x) + sin(x) tan(x) = sec (x)
Step-by-step explanation:
Consider LHS
[tex] \cos(x) + \sin(x) \tan(x) = \sec(x) [/tex]
Apply quotient identies
[tex] \cos(x) + \sin(x) \times \frac{ \sin(x) }{ \cos(x) } = \sec(x) [/tex]
Multiply the fraction and sine.
[tex] \cos(x) + \frac{ \sin {}^{2} (x) }{ \cos(x) } = \sec(x) [/tex]
Make cos x a fraction with cos x as it denominator.
[tex] \cos(x) \times \cos(x) = \cos {}^{2} (x) [/tex]
so
[tex] \frac{ \cos {}^{2} (x) }{ \cos(x) } + \frac{ \sin {}^{2} (x) }{ \cos(x) } = \sec(x) [/tex]
Pythagorean Identity tells us sin squared and cos squared equals 1 so
[tex] \frac{1}{ \cos(x) } = \sec(x) [/tex]
Apply reciprocal identity.
[tex] \sec(x) = \sec(x) [/tex]

Prove the identity. Sin(theta) cot(theta) sec(theta)=1
Answer:
Step-by-step explanation:
cot(theta) = cos(theta)/sin(theta)
sec(theta) = 1/ cos(theta)
sin(theta) * (cos(theta) ) / sin(theta) ) * 1/cos(theta)
The sin(theta)s and the cos(theta)s are on opposite sides of the division sign. So you are left with a bunch of ones.
The identity is proved.
Answer:
See below for explanation
Step-by-step explanation:
sinθcotθsecθ
sinθ(cosθ/sinθ)(1/cosθ)
sinθ(cosθ/sinθcosθ)
sinθ(1/sinθ)

The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of cos(0) is 5/13.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.
Given the value of Sin(0) is (12/13). Therefore, the perpendicular is 12, while the hypotenuse is 13. Therefore, the base will be,
13² = 12² + Base²
Base = 5
The value of Cos(0) will be,
Cos(0) = 5/13
Hence, the value of cos(0) is 5/13.

Find all vertical asymptotes of the following function f(x)=9x^2-64/2x+14
Answer:
Step-by-step explanation:
Was the latter half of this function, -64 / 2x + 14, meant to be:
-64 / 2x + 14, or
-64 / (2x + 14)?
In the first case the vertical asymptote is x = 0.
In the second, the vertical asymptote is the root of 2x + 14, or x = -7

A circle has a circumference of 615.44 point, 44 units.
What is the radius of the circle?
The circumference of a circle is equal to C=2πr
From the question, we have 615.44.
Assume that pi is equal to 3.14
Substitute and solve for r
615.44= 2(3.14)r
r= 615.44/ 6.28
r=98.4704
r=98
Therefore, the radius is about 98 units.
To check:
C=2πr
C=2 x 3.14 x 98
C=6.28 x98
C=615.44

This year there was 25% fewer sunny days than last year. What is the number of sunny days this year?
Answer:
The number of sunny days this year = 0.75x
where, x is the sunny days in last years.
Step-by-step explanation:
Given - This year there was 25% fewer sunny days than last year.
To find - What is the number of sunny days this year?
Proof -
Let us assume that,
The total number of sunny days last year = x
Given that,
This year there was 25% fewer sunny days than last year.
i.e this year total sunny days = 100 - 25 = 75 %
So,
we get
If there were x sunny days last year,
Then,
This year Total sunny days = 0.75x
The line y = 6 - 2x passes through the point (2, 2)
is it correct?
Answer:
Yes
Step-by-step explanation:
We can substitute the point (2, 2) into the equation. So, in place of x would be 2 and in place of y would be 2 as well:
y = 6 - 2x
2 = 6 - 2(2)
2 = 6 - 4
2 = 2
Since the above is a true statement, the point (2, 2) must belong to the line y = 6 - 2x
Yes, the line y=6-2x passes through the point (2, 2).
Given that, the line y=6-2x passes through the point (2, 2).
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
Here, substitute (x, y)=(2, 2) is the given line y=6-2x, we get
2 = 6-2(2)
2 = 2
Since, LHS = RHS
Yes, the line y=6-2x passes through the point (2, 2).
