Step-by-step explanation:

Add the values

x - y = 6

x + y = 2

-------------

2x = 8

--------------

Substitute for x

2x = 8

x = 8/2

x = 4

insert x = 4 into equation x - y = 6

x - y = 6

4 - y = 6

-y = 6 - 4

-y = 2

-y/-1 = 2/-1

y = -2

∴ y = -2 , x = 4

We can conclude after answering the provided question that So the equation answer is 50.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the statement "2x + 3" equals the value "9". The goal of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complex, regular or nonlinear, and include one or more factors. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are used in many different areas of mathematics, such as algebra, calculus, and geometry.

The mean of the sampling distribution of \($\overline{X}_R - \overline{X}_M$\)can be calculated using the following formula:

\($E(\overline{X}_R - \overline{X}_M) = E(\overline{X}_R) - E(\overline{X}_M)$\)

The mean of the sampling distribution of\($\overline{X}_R$\)can be calculated as:

\($E(\overline{X}_R) = \mu_R = 140$\)

The mean of the sampling distribution of \($\overline{X}_M$\)can be calculated as:

\($E(\overline{X}_M) = \mu_M = 90$\)

Therefore, the mean of the sampling distribution of\($\overline{X}_R - \overline{X}_M$\) can be calculated as:

\($E(\overline{X}_R - \overline{X}_M) = \mu_R - \mu_M = 140 - 90 = 50$\)

The coterminal angle of 7π / 6 will be 19π / 6.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. Coterminal angles are those with a common terminal side that are in standard position (angles with the initial side on the positive x-axis). For instance, the coterminal angles are 30°, -330°, and 390°.

Given the angle is 7π / 6 then the coterminal angle of the given angle will be calculated as below:-

Coterminal angle = a + 2π

Where a is the given terminal angle that is 7π / 6. Put the value of the terminal angle.

Coterminal angle = a + 2π

Coterminal angle = ( 7π / 6 ) + 2π

Coterminal angle = 19π / 6

Therefore, the value of the coterminal angle would be 19π / 6.

Answer:

Hence the distribution will be between 600 hours and 900 hours is 74.9%.

Step-by-step explanation:

The absolute value of the Rational number -474/513 is 474/513.

To find the sum of the rational numbers -8/9 and -2/57, you need to have a common denominator. The least common multiple (LCM) of 9 and 57 is 513. So, you can rewrite the fractions with a common denominator:

-8/9 = (-8/9) * (57/57) = -456/513

-2/57 = (-2/57) * (9/9) = -18/513

Now, you can add the fractions:

-456/513 + (-18/513) = (-456 - 18)/513 = -474/513

To find the absolute value of the rational number -474/513, you simply ignore the negative sign and take the value as positive:

| -474/513 | = 474/513

Therefore, the absolute value of the rational number -474/513 is 474/513.

Step-by-step explanation:

We can plug in 7 for a and 3 for b.  Then we can simplify

11(a + b)

Thus, the value of 11(a + b) when a = 7 and b = 3 is 110, or answer a

10% of the time, the population mean will go below $1,500 or exceed $2,100.

Given that,

Assume that we have data on the annual spending on apparel of a sample of families. The probability that the population mean will fall below $1,500 or rise over $2,100 is ________% if we are 90% positive that the genuine population mean will be between $1,500 and $2,100.

We have to fill the blank.

We know that,

90% of the time, the real population mean will fall in the range of $1,500 and $2,100.

The genuine population mean will therefore most likely fall between $1,500 and $2,100, with a 90% probability.

So, the probability that it will fall outside of this range (i.e., be either less than $1,500 or beyond $2,100) is 100-90, or 10%.

Therefore, 10% of the time, the population mean will go below $1,500 or exceed $2,100.

Answer:

  D.  Figures a and d

Step-by-step explanation:

You want to identify the shapes that are congruent.

Shapes are congruent if corresponding angles are congruent and corresponding line segments are congruent.

Here, the designated shape appears to be a right triangle with legs of different lengths. Shapes 'a' and 'd' also appear to be right triangles, with legs approximately the same lengths as those of the starred figure.

Figures 'a' and 'd' are congruent to the starred figure.

__

Additional comment

It is usual for geometry problems to rely only upon markings for congruence. That is, in general, you are not to rely upon appearance to draw conclusions about a geometry.

Here, none of the figures have any marks, so we cannot say with certainty that any of the segments or angles are congruent. Using these rules, the answer must be C. None of the shapes are congruent.

You may be able to reach a conclusion about what rules apply by looking at other problems and examples in your curriculum materials.

The values of x for the tangent segments to the circles are: (25). x = 2 and (26). x = 4

A theorem of tangents to a circle states that if from one exterior point, two tangents are drawn to a circle then they have equal tangent segments.

(25). 2x - 1 = x + 1 {equal tangent segments}

2x - x = 1 + 1 {collect like terms}

x = 2

(26). 2x - 4 = x {equal tangent segments}

2x - x = 4 {collect like terms}

x = 4

Therefore, the values of x for the tangent segments to the circles are: (25). x = 2 and (26). x = 4

The time that it will take the ball to hit the ground in 4 seconds.

To solve this problem you need the function;

h(t) = -16t² + v₀t + h₀

where;

t = time

v₀ is the initial velocity, which in our case is 0

h₀ is initial height, which in our case is 121 ft

h(t) = 0 since we want to know when the ball will hit the ground.

Thus;

0 = -16t² + 121

And we can solve for t;

If we rearrange the terms we see that this is a difference of 2 squares

0 = 121 - 16t²

0 = (11 - 4t)(11 + 4t)

Setting each factor = 0 gives;

11 - 4t = 0       11 + 4t = 0

t = 11/4       or      t = -11/44

The second solution is discarded as time cannot be negative.

Thus, the ball will hit the ground in 4 seconds.

a = 8; b = 0; c = -8; parabola opens upward; y intercept at (0, -8)

=========================================================

Reason:

The given equation is the same as y = 8x^2 + 0x - 8

Compare this to y = ax^2+bx+c

We see that

This rules out choice C because the a,b,c values don't match perfectly.

The parabola opens upward because a > 0, aka 'a' is positive. A positive 'a' value makes the parabola form a positive smile (in contrast to 'a' being negative to make a negative frown). This rules out choice A.

The y intercept always occurs when x = 0. Plug it in to get

y = 8x^2 - 8

y = 8(0)^2 - 8

y = -8

The y intercept is located at (x,y) = (0,-8). This rules out choice B.

A Venn diagram is a visual representation that makes use of circles to highlight the connections between different objects or limited groups of objects.

Circles that overlap share certain characteristics, whereas circles that do not overlap do not.

Venn diagrams are useful for showing how two concepts are related and different visually.

When two or more objects have overlapping attributes, a Venn diagram offers a simple way to illustrate the relationships between them.

Venn diagrams are frequently used in reports and presentations because they make it simpler to visualize data.
