The angle 67.5 degrees is 3 times its complement

Let us assume that the complement of the angle be p degrees.

Given that the measure of the angle is three times its complement.

So, the measure of the angle = 3p

We know that two angles are complementary when their measures add to 90 degrees.

The sum of complementary angles is 90 degrees.

So we get an equation, p + 3p = 90

We solve this equation to find the value of p.

p + 3p = 90

4p = 90

p = 90/4

p = 22.5 degrees

so, the measure of complement of the angle is 22.5 degrees.

And the required angle would be, 3 × 22.5 = 67.5 degrees

We have, some parts of California are particularly earthquake-prone.Suppose that in one metropolitan area, 31% of all homeowners are insured against earthquake damage. Four homeowners are to be selected at random.

Let X denote the number among the four who have earthquake insurance. The probability that the homeowner are insured against earthquake is 0.31. Let S denote a homeowner that has insurance and F denote a homeowner that does not has insurance.

a) For X = 0, {FFFF}

The probability of X = 0

= 0.69x0.69x0.69×0.69

= 0.22667

For X = 1, {SFFF, FSFF, FFSF, FFFS}

P( X = 1) = (0.31 x0.69x0.69×0.69) *4)

= -0.40735116

For X = 2,{SSFF, SFSF, SFFS, FSSF, FSFS, FFSS}

P(X= 2) = (0.31x0.31x0.69×0.69)*6

= -0.27451926

For x = 3,{SSSF, SSFS, SFSS, FSSS}

= (0.31x0.31x0.31x0.69) *4

(b) The most likely value for X is X = 1, since it has large probability comparing with other values.

(c) We have to calculate the probability that at least two of the four selected have earthquake insurance, P(X ≥2)= P(X=2)+ P(X=3) + P(X=4)

As per the given coordinates (-2, 3), the mirror image is (2,3)

In math the term coordinate is defined as  a set of values which helps to show the exact position of a point in the coordinate plane.

Here we have given the coordinates as (-2,3) and we need to find the mirror image on y axis.

The general term for the mirror image on y axis is written as,

=> (x, y) = (-x, y)

Which the rule defines that the sign of x coordinate is changed when we calculate the mirror image on y axis.

Therefore here we have to change the sign of x coordinate that is -2, then we get the mirror image as,

The total volume of ice cream served per cone V=256πcm³

The volume of a cone defines as the space or the capacity of the cone. It is a three-dimensional geometric shape having a circular base that tapers from a flat base to a point called an apex or vertex.

Given that radius of a cone is r=4 centimeters.

Ice Cream serves 3 scoops of ice cream in its signature cone.

To calculate the total volume of ice cream cones we have a formula:

V=4/3πr³.

Substitute the radius we get:

V=4/3π(4)³*3

V=4/3π(64)*3

V=256π

The equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.

The equation y = 2x - 4 can be written in slope-intercept form as y = 2x + b, where b is the y-intercept. To find the slope and y-intercept of the equation, we need to solve for b.

The y-intercept is the point where the line crosses the y-axis. To find the y-intercept, we can set x equal to 0 in the equation to get y = 2(0) - 4. This simplifies to y = -4, so the y-intercept is -4.

The slope is the rate at which the line rises. To find the slope, we can take the coefficient of x, which is 2. So the slope of the equation y = 2x - 4 is 2.

In summary, the slope of the equation y = 2x - 4 is 2 and the y-intercept is -4. We can write the equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.

If the variance is unknown and the sample size is small, then the t-test statistic is appropriate to use.

The t-test is a statistical hypothesis test used to identify whether an unknown population mean is different from a particular value. A t-test is appropriate to use when there is a small random sample collected from some statistical population and the sample is required to be compared with the mean from the sample to another value. Also, the variance of the sample is not known.

Thus, a t-test is appropriate to be used when the population variance or standard deviation is not known, and a sample size is less than 30.

The future value of $2000 at a 3% interest rate compounded annually for 3 years would be $2185.40.

The future value of $2000 at a 3% interest rate compounded annually for 3 years can be calculated using the formula:

FV = PV * (1 + r)ⁿ

where PV is the present value, r is the annual interest rate, and n is the number of compounding periods.

In this case:

FV = $2000 * (1 + 0.03)³

FV = $2000 * 1.03³

FV = $2000 * 1.0927

The equation pair cannot be solved if the lines are parallel.

Although a system of linear equations typically has a single solution, it occasionally may have infinite or no solutions (parallel lines) (same line). When the graphs cross at a particular point, a system of linear equations has a single solution.

When the graphs are parallel, an equation system with linear components cannot be solved. The graphs of a system of linear equations have an infinite number of solutions. The lines must connect since the slopes differ. The system of equations that the lines represent has just one solution since the lines intersect at a specific place.

Option D is the correct answer.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥
