The measure of an angle m ∠YBA=47°.

In Euclidean geometry, an angle is a figure made up of two rays that have a shared vertex, also known as a common terminus, and are referred to as the angle's sides. The angles of two rays are situated in the plane containing the rays. An angle is also created when two planes intersect at an angle. These are referred to as dihedral angles. Another technique to define two curves is to specify the angle generated by rays that are tangent to the intersection of two curves. Angle is another word for how long a rotation or angle is.

Since,

ΔFBA=ΔYBA

The two triangles in the provided illustration are comparable.

So,

From the figure:

m ∠FBA=47°

So, m ∠YBA=47°

Therefore, the measure of angle  m ∠YBA=47°

From the linear function, the rate of change is 35 and the unit cost is 35

A linear function is defined as a function that has either one or two variables without exponents.

In this problem, we have to write a linear function that models the table given. This will take the form of y = mx + c

m = slope or rate of change and c = constant or unit cost of the product.

The formula of slope of a line is given as

m = y₂ - y₁ / x₂ - x₁

Taking two points from the table;

m = 215 - 180 / 5 - 4

m = 35

Using the slope of the line, we can find the y - intercept of the function.

y = mx + c

215 = 35(5) + c

215 = 175 + c

c = 215 - 175

c = 40

The linear function of the table is y = 35x + 40

To test the claim that the two samples described come from populations with the same mean, we can use a two-sample t-test.

(a) The degree of freedom is 27

(b) The test statistic is -2.67

(c) Determine the rejection region for the test of H0:μ1−μ2=0 and Ha:μ1−μ2≠0 : we do not reject the null hypothesis.

(d) |t| > 2.70

(1) The degree of freedom for the two-sample t-test is calculated as

(2) The test statistic for the two-sample t-test is calculated as:

Plugging in the values, we get:

(3) To determine the rejection region for the test, we can use a significance level of α = 0.01. For a two-tailed test with α = 0.01, the critical value for t is approximately 2.70. Since our test statistic (-2.67) is less than the critical value, we do not reject the null hypothesis.

(4) For the rejection region, we need to consider values of t that are either greater than or less than the critical value. Therefore, we need to consider |t| values that are greater than 2.70. |t| > 2.70.

Answer: 8,000

Step-by-step explanation: So, to find how to round this to the nearest 1000, we need to look at the 3 digits being the 7. So, 899 is greater than 500, so we round up, so 7 + 1 is 8, and we change those 3 digits behind the zero to 0's, so we get 8,000. I hoped this helped.

Answer:

8000

7899 rounded to nearest thousand is 8000, because 7 is in thousand's place value, and the number after that is 8, which is more than 5, so 1 is added to 7, and it becomes 8. The rest of the numbers turn to 0.

Answer:

The area of the shaded region is 36.

In rectangle ABCD, point E lies halfway between sides AB and CD and halfway between sides AD and BC. This means that line segment AE is parallel to line segment CD and is half as long, and line segment BE is parallel to line segment AD and is also half as long.

Since AE is half as long as CD, and CD is twice as long as AE, we can say that CD is equal to 2 * AE. Similarly, since BE is half as long as AD, and AD is twice as long as BE, we can say that AD is equal to 2 * BE.

Since AD is equal to 2 * BE and CD is equal to 2 * AE, the lengths of AD and CD are equal. This means that the shaded region is a parallelogram with sides of equal length.

The area of a parallelogram is equal to the product of its base and height. In this case, the base of the parallelogram is 6 (the length of side BC) and the height is AE + BE (the combined length of the two sides of the parallelogram).

We know that AE is half as long as CD, and CD is twice as long as AE, so CD is equal to 2 * AE. Since CD is equal to 2 * AE, AE is equal to CD / 2. Since CD is equal to 11 (the length of side AB), AE is equal to 11 / 2 = 5.5.

Similarly, we know that BE is half as long as AD, and AD is twice as long as BE, so AD is equal to 2 * BE. Since AD is equal to 2 * BE, BE is equal to AD / 2. Since AD is equal to 6 (the length of side BC), BE is equal to 6 / 2 = 3.

The combined length of AE and BE is 5.5 + 3

Step-by-step explanation:

The equation for the area of a circle is

[tex]A=\pi r^2[/tex]

Since the problem does not give a value for r, it must be derived.  Recall that the equation for the circumference of a circle is

[tex]C=2\pi r[/tex]

Using the given value of the circumference,

The chromosomes in the image are called sex chromosomes, and the chances of being born male or female are 1:1.

In Science, a chromosome can be defined as a thread-like linear strand of deoxyribonucleic acid (DNA) that is typically found in the nucleus of each cell in a living organism.

In Genetics, some of the characteristics of a chromosome include the following:

Furthermore, the human somatic cell primarily comprises 46 chromosomes which are normally sub-divided into 23 pairs of chromosomes with 22 of these pairs being autosomes and a pair of sex chromosomes (X and Y).

In this context, we can reasonably infer and logically deduce that the x and y chromosomes are generally referred to as sex chromosomes.

Step-by-step explanation:

1 [tex]\frac{3}{5}[/tex] = 8/5

3 [tex]\frac{2}{3}[/tex] = 11/3

In order to add fractions, the denominators, or the bottom numbers, have to be the same. To make them the same, find the common denominator (the lowest number that both the numbers can be divisible by)

8/5+ 11/3  the common denominator would be 15 so multiply the appropriate numbers to the denominators and the numerators (the top number)

24/15 + 55/15 = 79/15

Now simplify

Since H0 is not rejected so, the mean life of a contain brand of tire used by it's trucks is not less than 35,000 miles.

What is standard deviation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

A shipping firm suspects that the mean life of a certain brand of tire used by its trucks is less than 35,000 miles.

To check the claim, the firm randomly selects and tests 18 of these tires and gets a mean lifetime of 34,200 miles with a standard deviation of 1200 miles.

At α = 0.05, test the shipping firm's claim.

Under H0: μ 200  Vs H1: > 200  (Right tailed test)

n = 16, x bar = 205 , s = 14

Null Hypothesis;  H0:  μ = 35000  Vs  H1: < 35000

(Mean life of brand of tire less than 35000 miles).

Under H0 test statistic is

t = (x bar - μ) / (s / √n) ≈ [tex]t_n_-_1[/tex]

Now, n = 18, x bar = 34,200,  s = 12000

t = (34000 - 35000) / (1200 / √18) = -2.8284

t - critical value of α = 0.05 for left tailed at (18 - 1) df = -2.11

Therefore t calculated (= -2.8284) < -2.11

So, we do not reject H0.

Hence, since H0 is not rejected so, the mean life of a contain brand of tire used by it's trucks is not less than 35,000 miles.

Step-by-step explanation:

First, find the slope of the equation:

m=(y2-y1)/(x2-x1)  ==> m=slope of equation

(x1, y1), (x2, y2) ==> (x1=3, y1=4), (x2=2, y2=1)

m=(1-4)/(2-3)  ==> plugin x1=3, y1=4, x2=2, and y2=1

m=-3/(-1)

m=3

y=mx+b   ==> slope-intercept equation

1=3(2)+b ==> plugin 3 for m and (2, 1) where x=2 and y=1

1=6+b ==> solve for b

1-6=6-6+b

b=-5

y=3x+(-5)  ==> plugin -3 for m and -5 for b

y=3x-5 ==> simplify

Now, Isolate -5 since it is the only constant

y-3x=3x-3x-5  ==> isolate -5 by subtracting 3x on both sides

-3x+y=-5  ==> simplify and put in Ax+By=C form

y = 3x - 5

0.007 places is a decimal representation of a number. In the decimal system, the value of a digit is determined by its position relative to the decimal point. In this case, the number 0.007 has three digits to the right of the decimal point, so it is said to have three decimal places. The value of each digit in this number is determined by its position: the first digit (0) is in the hundredths place, the second digit (0) is in the thousandths place, and the third digit (7) is in the ten-thousandths place.
