Answer:
46
Step-by-step explanation:
angles that are supplementary add up to 180 so make equation x + 134 = 180
solve.
Answer:
∠A = 46°
Step-by-step explanation:
Supplementary means that 2 or more angles add up to the sum of 180°, So we can say;
∠I + ∠A = 180
134 + ∠A = 180
∠A = 180 - 134
∠A = 46°
Therefore, we can conclude that the measure of ∠A is 46°.

Use the formula C(n, x)pxqn − x to determine the probability of the given event. (Round your answer to four decimal places.) The probability of exactly no successes in seven trials of a binomial experiment in which p = 1/4
Answer: 0.1334
Step-by-step explanation:
Given
There are seven trails with a probability of success is [tex]p=\frac{1}{4}[/tex]
[tex]\therefore q=1-p\\q=1-\frac{1}{4}\\q=\frac{3}{4}[/tex]
Using the binomial distribution, the Probability of exactly no success i.e. x=0 is given by
[tex]\Rightarrow ^7C_0\cdot p^0 \cdot q^{7-0}\\\Rightarrow 1\times(\frac{1}{4})^0 \cdot (\frac{3}{4})^7\\\Rightarrow 1\times 1 \cdot (0.75)^7\\\Rightarrow 0.1334[/tex]

5. Find dy/dx of
of the following
the following functions
y²= 4ax
Answer:
A general rule for functions of the general form:
y = A*x^n
is:
dy/dx = n*A*x^(n - 1)
Then, for the function:
y^2 = 4*a*x
Then we can rewrite this as:
y = (4*a*x)^(1/2) = √(4*a)*x^(1/2)
Then we have:
A = √(4*a)
n = 1/2
Now we can use the above rule to get
dy/dx = (1/2)*√(4*a)*x^(1/2 - 1)
dy/dx = (1/2)*√(4*a)*x^(-1/2)
dy/dx = (1/2)*√(4*a/x)
dy/dx = √(1/4)*√(4*a/x)
dy/dx = √( (1/4)*4*a/x)
dy/dx = √(a/x)

Answer:
Obtuse
Step-by-step explanation:
Right = has angle measure of 90°
Acute = has angle measure less than 90°
Equilateral = 2 or more angles whose angle measures are congruent to others
Circle = measures 360°
Obtuse = Angle measure greater than 90° and less than 180°

Given that ΔWKM ≅APR, which angle is congruent to ∠K?
A ∠W
B ∠R
C ∠P
D ∠A
Answer:
C
Step-by-step explanation:
Given the triangles are congruent then corresponding angles are congruent.
The angle corresponding to K in the other Δ is P, they are in the same position Δ APR and Δ WKM
∠ P is congruent to ∠ K
2. Mr. Bowen’s test is normally distributed with a mean of 75 and a standard deviation of 3 points. Part A: What is the probability that a randomly selected score is greater than 81 points? Part B: What percentage of students scores are between 69 and 78? Part C: A student who scores a 84 is in the _______________ percentile.
Using the normal distribution, it is found that:
A. There is a 0.0228 = 2.28% probability that a randomly selected score is greater than 81 points.
B. 81.85% of students scores are between 69 and 78.
C. The student scored in the 99.87th percentile.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, as:
[tex]\mu = 75, \sigma = 3[/tex].
Item a:
The probability is one subtracted by the p-value of Z when X = 81, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{81 - 75}{3}[/tex]
Z = 2.
Z = 2 has a p-value of 0.9772.
1 - 0.9772 = 0.0228.
0.0228 = 2.28% probability that a randomly selected score is greater than 81 points.
Item b:
The proportion is the p-value of Z when X = 78 subtracted by the p-value of Z when X = 69, hence:
X = 78:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{78 - 75}{3}[/tex]
Z = 1.
Z = 1 has a p-value of 0.8413.
X = 69:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{69 - 75}{3}[/tex]
Z = -2.
Z = -2 has a p-value of 0.0228.
0.8413 - 0.0228 = 0.8185.
81.85% of students scores are between 69 and 78.
Item c:
The percentile is the p-value of Z when X = 84, multiplied by 100, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{84- 75}{3}[/tex]
Z = 3.
Z = 3 has a p-value of 0.9987.
The student scored in the 99.87th percentile.

Function A and Function B given below are linear functions, which statement is
true?
Answer:
a
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
Slope Formula: Y2 - Y1/ X2 - X1
Function A: 15 + 25/ 4 + 4 = 5; Slope = 5
Function B: 4 - 2/ 3-2 = 2; Slope = 2
The slope of Function A is greater than the slope of Function B.
if a=b and b = 25 ,what is a + 24
Answer:
a=29
Step-by-step explanation:
If a=b and b is 25
Then a is 25
25+24=49
Answer:
I believe the answer is 49. This is because if B = 25 and A = B, therefore, A = 25 and 25 + 24 = 49.

B. $7.99 for 5 scoops
C. $9.59 for 8 scoops
Answer:
C
Step-by-step explanation:
on C 1 ice cream cost $1.2 if you multiply 1.2x12=14.4
THE CORRECT ANSWER IS...
C ($9.59 for 8 scoops)
Step-by-step explanation:
well, if you divided 14.89 by 12 it equals $1.24. so that means it's $1.24 for one single scoop for that one. then for B if you divided $7.99 by 5, you'd get $1.60, so that's $1.60 per scoop for B. lastly $9.59 divided by 8 is $1.20, which is the lowest price per scoop, so that makes it the best and most affordable one. i hope i explained that easily, but basically all in all, the answer is C.
The correct answer is in BOLD.

Answer:
Option 1.) y = 125°
Step-by-step explanation:
We know that sum of exterior angles of any polygon is 360°. Therefore we can say;
70° + 60° + 65° + 40° + y° = 360°
235° + y° = 360°
y = 360 - 235
y = 125°
Therefore the measure of ∠y = 125°

how do you find the slope from x+y=3?
Answer:
y=-x+3
Step-by-step explanation:
To find slope, you would want to use the formula for slope which is y=mx+b.
we are basically isolating the "y". So to find slope we would just subtract the "x" from both sides, leaving use with a negative "x" plus 3 on one side and a y on the other.

Find the AREA of the triangle below. Round your answer to the nearest tenth. I sad 15 I am not sure if its correct
Answer:
11 sq. units
Step-by-step explanation:
Find the area of the rectangle first, then find the area of the three white triangles.
Area of the rectangle
= 6×5
= 30 sq. units
Total area of the three white triangles
= (4×5)÷2 + (2×3)÷2 + (6×2)÷2
= 19 sq. units
The area of the rectangle minus the total area of white triangles:
Area of the green triangle
= 30-19
= 11 sq. units
