Explanation:The area of a triangle is given by the following formula:
[tex] \\ [/tex]
[tex] \left[ \begin{array}{c c c} \underline{\tt Area \ of \ a \ triangle \text{:}} \\ ~ \\ \tt A = \dfrac{B \cdot H}{2} \end{array} \right] [/tex]
Where:
A is the area of the triangle.B is the base.H is the height.[tex] \\ [/tex]
[tex] \Large{\boxed{\sf Given \text{:} } \ \begin{cases} \sf A &=\sf 66 \ in^2 \\ \sf B &=\sf 11 \ in \end{cases} } [/tex]
[tex] \\ [/tex]
Substitute these values into the formula and solve for H.
[tex] \sf A = \dfrac{B \cdot H}{2} \\ \\ \\ \longrightarrow \sf 66 \ in^2 = \dfrac{11 \ in \cdot H}{2} [/tex]
[tex] \\ [/tex]
Multiply both sides by 2:
[tex] \longrightarrow \sf 66 \ in^2 \cdot 2 = \dfrac{11 \ in \cdot H}{2} \cdot 2 \\ \\ \\ \longrightarrow \sf 132 \ in^2 = 11 \ in \cdot H [/tex]
[tex] \\ [/tex]
Divide both sides by 11in :
[tex] \longrightarrow \sf \dfrac{132 \ in^2 }{11 \ in } = H \\ \\ \\ \longrightarrow \boxed{\boxed{\sf H = 12 \ in}} [/tex]

A triangle has an area of 66 in². If the base is 11 inches, what is the height?
Answer:The height of the triangle is 12 inches.
Step-by-step explanation:As per the provided information in the given problem, we know that the area of a triangle is given by 66 inches². The base of the triangle is given by 11 inches. In this problem, we are tasked to find the height of the triangle.
To do this, we will use the formula below:
[tex]\Large\begin{aligned}\rm\qquad\dashrightarrow{Area_{(Triangle)} = \dfrac{1}{2}bh}\end{aligned}[/tex]
Where:
The base is denoted as b.The height is denoted as h.Substitute the given values into the formula given earlier and solve for h:
[tex]\Large\begin{aligned}\rm\dashrightarrow{Area_{(Triangle)}}& = \rm{\dfrac{1}{2}bh}\\\rm\dashrightarrow{66\: in^2}& = \rm{0.5(11\: in)(h)} \\\rm\dashrightarrow{66\: in^2}& = \rm{(5.5\: in)(h)} \\\rm\dashrightarrow{\dfrac{66\: in^{\cancel{2}}}{5.5\: \cancel{in}}}& = \rm{\dfrac{(\cancel{5.5\: in})(h)}{\cancel{5.5\: in}}} \\\rm\dashrightarrow{12\: in}& = \rm{h}\end{aligned}[/tex]
Hence, the height of the triangle is 12 inches.

Answer:
Step-by-step explanation:
First, you have to find the degress for m<A.
m<A+ 90+37=180
m<A+ 127=180
then you subtract 127 from both sides.
So, m<A= 53 degress, We already know that m<B is 90,
So let's solve for m<C.
m<C + 53+ 90= 180
m<C+ 143=180
m<C= 37 degress.
Since the triangles are both the same and has the same length and are congruent polygons
m<X=53 degress, m<Y= 90 degress, and m<Z= 37 degress

Determine the value(s) for which the rational expression 5x6x is undefined. If there's more than one value, list them separated by a comma, e.g. x=2,3.
Explanation:
We cannot have zero in the denominator. If x = 0, then the denominator 6x becomes 6x = 6*0 = 0. So we must exclude this from the domain to avoid a division by zero error.
One could argue that the 'x's cancel out when we divide. Yes that's true and [tex]\frac{5x}{6x} = \frac{5}{6}[/tex], but as far as the calculator is concerned, it will not try to simplify the expression (unless it's a specific type of calculator). Instead, the calculator would likely follow the order of operations PEMDAS to try to compute directly. The calculator would hit the stumbling block of dividing by zero and produce "undefined" or "not a number".

I took the test.
The quadratic regression equation best fits the data set is 2.608x² -155.264x + 1568.064 option second is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
Let's suppose the quadratic regression equation best fits the data set:
y = Ax² + Bx + C
From the data set, we can calculate the value of the A, B and C:
A = 2.608
B = -155.264
C = 1568.064
y = 2.608x² -155.264x + 1568.064
Thus, the quadratic regression equation best fits the data set is 2.608x² -155.264x + 1568.064 option second is correct.

Step-by-step explanation:
you should have measured the lengths of the sides and added that information here to the picture.
because we here cannot measure this from a picture that is inclined and has no size scale.
I can give you a hint how to get the angles, when you have all 3 sides :
start with the extended Pythagoras for non right-angled triangles:
c² = a² + b² - 2ab×cos(C)
with c being the side opposite of the angle you are aiming for.
then
2ab×cos(C) = a² + b² - c²
cos(C) = (a² + b² - c²)/(2ab)
for example, to get the angle at T, its opposite side is SE.
cos(T) = (ST² + ET² - SE²)/(2×ST×ET)
you can do the same thing for all 3 angles (you need to always pay attention to what sides you have to use in what combination for the angle).
or you can switch after getting the first angle to the laser of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the disposing angles are always opposite of each other.
for your triangle that looks like
ET/sin(S) = ST/sin(E) = SE/sin(T)
from there (once you have one angle via the Pythagoras approach) you get all other angles.

Rashaad owns a small business selling used books. He knows that in the last week 13 customers paid cash, 50 customers used a debit card, and 53 customers used a credit card. Based on these results, express the probability that the next customer will pay with a debit card as a fraction in simplest form.
Answer:
25/58
Step-by-step explanation: Ok, your step one should be to add all the previous customer values together to see what the total pool of values is. 13+50+53=116, this becomes your denominator. Then, you see that out of these 116 customers in the past week, 50 used a debit card. So based on this data, we can assume that 50 out of every 116 customers will use a debit card. The fraction is thus 50/116. Then it needs to be simplified. Divide the numerator and denominator by 2, and BAM 25/58 is your final answer.
Probability that next customer will pay with debit card is (25 / 58) (simplest fraction form).
What is probability?" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes for a given event."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Given,
Number of customers paid through cash = 13
Number of customers paid through debit card = 50
Number of customers paid through credit card = 53
Total number of customers = 13 + 50 + 53
= 116
Substitute the value in the formula we get,
Required probability = (50 / 116)
= (25 / 58) (simplest fraction form)
Hence, probability that next customer will pay with debit card is (25 / 58) (simplest fraction form).

Step-by-step explanation:
Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15).
a. A researcher suggests that a reason individuals wait until the last five days is that on average these individuals receive lower refunds than do early filers. Develop appropriate hypotheses such that rejection of H0 will support the researcherâs contention.
b. For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience a population standard deviation of Ï = $1600 may be assumed. What is the p-value?
c. At α = .05, what is your conclusion?
d. Repeat the preceding hypothesis test using the critical value approach.
Answer and Step-by-step explanation:
Solution:
Develop hypothesis:
H₀ : µ ≥ 1056
H₁ < 1056
Given:
n = 400
ẋ = 910
∂ = 1600
a = 0.05
The sampling distribution of sample means µ and standard deviation ∂ / √n.
Z = ẋ-µ /∂ / √n.
= 910 – 1056 / 1600 /√400.
= - 1.83
Probability: p = p(z< -1.83) = 0.033
At a = 0.05
If p value is smaller than significance level a, then hypothesis is rejected.
P < 0.05 its means H0 rejected.
Hypothesis test using critical value:
The critical value corresponding to probability of 0.05:
Z = -1.645
The rejection region, then contains all values smaller than -1.645.
If value of test statistics is within the rejection region, then null hypothesis rejected.
-1.83 < -1.645
