Given.

Transitive property of equality- this is becasue the rule is if A=b and B=c then A=c. IN this situation its saying that a is parrelel to b and b is parralel to c therfore a is parrelel to c.

line A and d cross over at 90 degree angles making them perpendicular. -There should be a rule for this and if there is then write that rule down

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

Rejected H

Answer:

C)  1340 days

Step-by-step explanation:

The composite function you have given is incorrect.

The composite function for this question is:

t(d) = 60d + 20

(as I have proven in a previous question)

Substitute d = 22 into the function:

t(22) = 60(22) + 20

        = 1320 + 20

        = 1340 days

Hey there!

The degree is the exponent.

Let me explain with examples.

Suppose we have a polynomial 4d.

Its degree is 1 (it's a first degree polynomial)

What is the degree of the polynomial 4d²?

That's right, this is a second-degree polynomial.

And so on...

Let's look at our polynomial.

We have

-7d.

What is the degree of the polynomial?

That's right, 1.

Hence, -7d is a

There are 450 even three-digit numbers.

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).

" 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).

Answer:

yˆ=2.608x2−115.265x+1568.065

Step-by-step explanation:

I took the test.

The quadratic regression equation best fits the data set is 2.608x²  -155.264x + 1568.064 option second is correct.

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.

Answer:

His change would be $1.27 because he paid $3.73 for the pen and marker.

Step-by-step explanation:

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.

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
