How do I solve this?
Answer:
x=60° , y=30° , z= 75°
Step-by-step explanation:
note...an equilateral triangle has the same angles all equal to 60°. so based on this x is 60°
the angle next to y is on a straight line therefore
60 +y =90
y=90-60
y=30°
the triangle with the y and z angles is an isosceles triangle...so the base angles must be equal
z+z+30=180
2z+30=180
2z=180-30
2z=150
[tex] \frac{2z}{2} = \frac{150}{2} [/tex]
z=75°

C4 Let B = {₁,...,V) be a set of vectors in R". Prove that if v₁ = Ổ for some i, then B is linearly dependent.
In this question, we are given a set of vectors B in [tex]R_{n}[/tex] and we need to prove that if there exists a vector v_i in B such that v_i is the zero vector, then the set B is linearly dependent.
To prove that if v_i is the zero vector for some i, then the set B is linearly dependent, we need to show that there exist scalars c_1, c_2, ..., c_n (not all zero) such that the linear combination c_1v_1 + c_2v_2 + ... + c_nv_n equals the zero vector.
Since v_i is the zero vector, we can choose c_i = 1 and c_j = 0 for j ≠ i. Then, the linear combination becomes c_1v_1 + c_2v_2 + ... + c_nv_n = v_i, which is the zero vector.
This implies that we have found a nontrivial linear combination of the vectors in B that equals the zero vector. Therefore, B is linearly dependent.
The reason behind this is that the presence of the zero vector in a set of vectors automatically guarantees linear dependence. Any set containing the zero vector can be linearly dependent because we can always choose the scalar coefficient of the zero vector to be non-zero, resulting in a nontrivial linear combination equaling the zero vector.

Consider the triangle below.
Need help ASAP.....
Answer: See below
Step-by-step explanation:
For part a, we are given that the triangle is an isosceles triangle. That means the two sides that are marked are equal to each other. We set DE and EF equal to each other to find x.
5x-3=3x+7 [subtract both sides by 3x]
2x-3=7 [add both sides by 3]
2x=10 [divide both sides by 2]
x=5
We now know the value of x is 5.
For part b, all we have to do is plug in x=5 to find the length of each leg.
5(5)-3 [multiply]
25-3 [subtract]
DE=22 in
3(5)+7 [multiply]
15+7 [add]
EF=22 in
Now, we have the length of each leg. DE=22 in, EF=22 in
For part c, we do the same as above and plug in x=5 to find the length of the base.
6(5)-3 [multiply]
30-3 [subtract]
DF=27 in
Now, we have the length of the base. DF=27 in

The value of logarithm base 2 of 32 is 5, indicating that 2 raised to the power of 5 equals 32.
The logarithm of a number to a given base represents the exponent to which the base must be raised to obtain that number. In this case, we want to find the exponent to which 2 must be raised to obtain 32.
By observing that 2^5 equals 32, we can conclude that log₂(32) is 5. This means that 2 raised to the power of 5 is equal to 32. Therefore, the logarithm of 32 to the base 2 is 5.

a ( b - c) = d solve for c
Answer:
c = b- d/a
Step-by-step explanation:
a ( b - c) = d
Divide each side by a
a/a ( b - c) = d/a
b-c = d/a
Subtract b from each side
b-c-b = d/a -b
-c = d/a -b
Multiply each side by -1
c = -d/a +b
c = b- d/a

Lori Jeffrey is a successful sales representative for a major publisher of college textbooks. Historically, Lori obtains a book adoption on 25% of her sales calls.

(a)
How large was the sample used in this analysis? That is, how many sales calls did Lori make during the month?
sales calls

Let
p
indicate the sample proportion of book adoptions obtained during the month. Show the sampling distribution of
p.
A bell-shaped curve is above a horizontal axis labeled p.
In order of left to right, the ticks on the horizontal axis are labeled: −0.0625, 0, 0.0625, 0.125, 0.1875.
The curve enters the viewing window near −0.0625 just above the horizontal axis and travels up to the right to a maximum near 0.0625.

(c)
Using the sampling distribution of
p,
compute the probability that Lori will obtain book adoptions on 15% or more of her sales calls during a one-month period. (Round your answer to four decimal places.)
The sample size used in this analysis, representing the number of sales calls Lori made during the month, is approximately 385.
The sample size used in this analysis, representing the number of sales calls Lori made during the month, can be determined using the standard error of the proportion and the desired level of confidence.
To calculate the sample size, we need to use the formula:
[tex]n = (Z^2 * p * (1 - p)) / E^2[/tex]
Where:
n = sample size
Z = z-score corresponding to the desired level of confidence
p = estimated proportion (historical book adoption rate)
E = margin of error (standard error of the proportion)
Given the standard error of the proportion as 0.0400, we can use this value as the margin of error (E). Assuming a 95% level of confidence, the corresponding z-score is approximately 1.96.
Plugging these values into the formula, we have:
n = (1.96^2 * 0.20 * (1 - 0.20)) / 0.0400^2
Simplifying the equation, we get:
n = (3.8416 * 0.20 * 0.80) / 0.0016
n = 0.61536 / 0.0016
n ≈ 384.6
Therefore, the sample size used in this analysis, representing the number of sales calls Lori made during the month, is approximately 385.

What is the result of 112 divided by 8? Use the number line to find the answer. A number line going from 0 to 128. The numbers 0, 16, 32, 48, 64, 80, 96, 112, and 128 are marked on the line. Marks divide the spaces between each number into 2 equal parts.
Answer:
14 =^.^=
Step-by-step explanation:
I GOT IT RIGHT ON EDGE 2020 >:3
The number 112 when divides by the number 8 gives the result 14.
To find the result of 112 divided by 8 using the number line, we can follow these steps:
1. Start at 0 on the number line.
2. Move along the number line in increments of 8 until you reach the number 112.
0 - 8 - 16 - 24 - 32 - 40 - 48 - 56 - 64 - 72 - 80 - 88 - 96 - 104 - 112
3. Count the number of times you moved in increments of 8.
It takes 14 increments of 8 to reach 112.
4. Therefore, 112 divided by 8 is equal to 14.
So, the result of 112 divided by 8 is 14.

-4x^(2)-3x+14=4 select all statements that apply
Answer:
x = - 2, x = [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
Given
- 4x² - 3x + 14 = 4 ( subtract 4 from both sides )
- 4x² - 3x + 10 = 0 ( multiply through by - 1 to clear the leading negative )
4x² + 3x - 10 = 0
Consider the product of the factors of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × - 10 = - 40 and sum = + 3
The factors are + 8 and - 5
Use these factors to split the x- term
4x² + 8x - 5x - 10 = 0 ( factor the first/second and third/fourth terms )
4x(x + 2) - 5(x + 2) = 0 ← factor out (x + 2) from each term
(x + 2)(4x - 5) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
4x - 5 = 0 ⇒ 4x = 5 ⇒ x = [tex]\frac{5}{4}[/tex]

Step-by-step explanation:
Here is the complete question
An ambulance require diesel as fuel because of so many trips nearby pump purchase diesel in bulk for the ambulance there are three containers at the pump which contain 403 L 434 L and 465 L of diesel respectively the maximum capacity of measuring container that can be measured the diesel of the three containers an exact number of times is
Solution
To find the exact number of times in which we can measure the diesel in the three containers, since the capacity of each container is 403 L, 434 L and 465 L respectively, we find the prime factors of each number.
The prime factors of 403 = 13 × 31
The prime factors of 434 = 2 × 7 × 31
The prime factors of 465 = 3 × 5 × 31
The measuring capacity equals the highest common factor (H.C.F) of the three numbers. That is H.C.F of 403, 434, 465.
Since it can be seen here that the H.C.F is 31, then the maximum capacity of measuring container that can be measured the diesel of the three containers an exact number of times is 31 L

What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Kiren is spending $12 on games and rides at a carnival where a game costs $0.25 and a ride costs $1.
Assume that Kiren played 'x' games and rides 'y' times.
Total amount with Kiren = A[T] = $12
Cost of game = A[G] = $0.25
