3% of 1500 is 45

1500 + 45 = 1545

Answer:

Step-by-step explanation:

I take it the unmarked angle on the top triangle should be Q

The way the triangles are marked the following are the statements.

<Q = < X                Given

RQ  = XZ               Given

XY =  PQ               Given

Is the angle included between the two given sides?

If yes then the Two Triangles are congruent by SAS

If no then the Two Triangles cannot be conclusively known to be congruent.

I have to leave you to figure out the flow chart symbols. I have no way of showing this as a flow chart if it is a computer program flow chart.  

Answer:

A 123 and b 246 i think so these follow ratio table

Step-by-step explanation:

The graph of a quadratic equation in two variables (y = ax^2 + bx + c ) is called a parabola. The following graphs are two typical parabolas their x-intercepts are marked by red dots, their y-intercepts are marked by a pink dot, and the vertex of each parabola is marked by a green dot: (Given in attachment for diagram)

We say that the first parabola opens upwards (is a U shape) and the second parabola opens downwards (is an upside down U shape). In order to graph a parabola we need to find its intercepts, vertex, and which way it opens.

Given y = ax^2 + bx + c , we have to go through the following steps to find the points and shape of any parabola:

Label a, b, and c.

Decide the direction of the paraola:

If a > 0 (positive) then the parabola opens upward.

If a < 0 (negative) then the parabola opens downward.

Find the x-intercepts:

Notice that the x-intercepts of any graph are points on the x-axis and therefore have y-coordinate 0. We can find these points by plugging 0 in for y and solving the resulting quadratic equation (0 = ax^2 + bx + c). If the equation factors we can find the points easily, but we may have to use the quadratic formula in some cases. If the solutions are imaginary, that means that the parabola has no x-intercepts (is strictly above or below the x-axis and never crosses it). If the solutions are real, but irrational (radicals) then we need to approximate their values and plot them.

Find the y-intercept:

The y-intercept of any graph is a point on the y-axis and therefore has x-coordinate 0. We can use this fact to find the y-intercepts by simply plugging 0 for x in the original equation and simplifying. Notice that if we plug in 0 for x we get: y = a(0)2 + b(0) + c or y = c. So the y-intercept of any parabola is always at (0,c).

Find the vertex (h,k):

To find the x-coordinate for the vertex we use the following formula:

To find the y-coordinate for the vertex we plug in h in the original equation:

k = a(h)2 + b(h) + c

Plot the points and graph the parabola

Answer:

1/6

Step-by-step explanation:

Given the following data;

A single fair die = 6

To find an outcome of A5;

Since the die was tossed just once, the outcome would be a fraction of the total number of outcomes.

P(A5) = number of times tossed/total number of outcomes

P(A5) = 1/6

Answer:

H0: mu = 120 , Ha: : mu not equal to 120

The p-value  is greater than or equal to 0.10

z= -1.636

Since the calculated value of  z does not fall in the critical region H0 is not rejected.

Step-by-step explanation:

State the null and alternate hypothesis

H0: mu = 120

average braking distance for a small car traveling at 65 miles per hour equals 120 feet.

against the claim

Ha: : mu not equal to 120

average braking distance for a small car traveling at 65 miles per hour  does not equal 120 feet.

The p-value equals 0.101764 which is greater than 0.01 and thus supports H0.

The p-value  is greater than or equal to 0.10

The test statistic z is applied

Here

Sample Mean  x~ = 114

Population mean μ =120

Sample size n= 36

Population SD =σ= 22

Z= u- μ/σ√n

Z= 114- 120/ 22/ √36

z= -1.636

This is a two tailed test and the critical region for two tailed test at alpha = 0.01 is z ∝/2= ± 2.58

Since the calculated value of  z does not fall in the critical region H0 is not rejected.

Statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct

It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.

We have:

Survey data involving two random samples of students at law school are shown. The surveys were taken, comparing the age of students in 1900 to the age of students in 2014.

The statements that are true about the two samples of students:

Thus, statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct

Answer:

Y = 10.1 + 1.50x

Step-by-step explanation:

From the data contained in the computer output for linear regression

The coefficient of intercept = 10.1

coefficient of fertilizer = 1.50

Sample of an Equation of least squares regression line

y = a + bx

where : a = intercept , b = slope

hence the required equation will be

Y = 10.1 + 1.50x

y = yield , x = fertilizer

Step-by-step explanation:

f(x) = x³-9x²+5x-2

now,

f(3) = 3³-9×(3)²+5×3-2

= 27-9×9+5×3-2

= 27-81+15-2

Step-by-step explanation:

Arc BC is twice the measure of inscribed angle BEC, so is ...

  arc BC = 2×50°

  arc BC = 100°

Answer:

Step-by-step explanation:

The inscibed angle E is 1/2 the measure of the central angle P so P is 100 degrees, and arc BC is also 100 degrees.

Answer:

Let's cut the figure into:

Parallelogram, square, and rectangle.

Let's find the area of the parallelogram first:

10 x 3.5 = 35

Let's find the area of the square:

4 x 4 = 16

When given one length of a square you already know are sides and lengths are equal so therefore 1 given length of a square is all the lengths.

Let's find the area of a rectangle:

6 x 12.5 = 75

Now let's add all the areas up:

35 + 16 + 75 = 126 square inches is your answer.

Answer:

Step-by-step explanation:

3/5x+30=150

We move all terms to the left:

3/5x+30-(150)=0

Domain of the equation: 5x!=0

x!=0/5

x!=0

x∈R

We add all the numbers together, and all the variables

3/5x-120=0

We multiply all the terms by the denominator

-120*5x+3=0

Wy multiply elements

-600x+3=0

We move all terms containing x to the left, all other terms to the right

-600x=-3

x=-3/-600

x=1/200
