(Numbers from 1 to 10 equal to or greater than 7 are 7 and 9)

Step-by-step explanation:

We have to find the set of whole number greater than and equal to 7 from 1 to 10,

Now, From 1 to 10, the odd numbers are, 1,3,5,7,9,

And of these, 7 and 9 are equal to or greater than 7

So, we get the set,

The equation of the axis of symmetry of the parabola is equal to x = 4.

In this problem we find the representation of a parabola whose axis of symmetry is parallel with y-axis. The axis of symmetry passes through the vertex of the parabola. The definitions of the vertex and the axis of symmetry are, respectively:

Vertex

(x, y) = (h, k)

Axis of symmetry

x = h

If we know that h = - 4, then the equation of axis of symmetry is x = 4.

The probability that next year there will be no snowfall in that town on January 1 is,

P (no snowfall) = 0.770

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

We have to given that;

Based on a weather record, the probability of snowfall in a certain town in New York on January 1 is 0.230.

Now, WE get;

the probability that next year there will be no snowfall in that town on January 1 is,

P (no snowfall) = 1 - P (snowfall)

P (no snowfall) = 1 - 0.230

P (no snowfall) = 0.770

Thus, The probability that next year there will be no snowfall in that town on January 1 is,

P (no snowfall) = 0.770

There is a 0.9968 probability that a randomly selected 50-year-old female lives through the year (based on data from the U.S. Department of Health and Human Services).

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

A Fidelity life insurance company charges $226 for insuring that the female will live through the year. If she does not survive the year, the policy pays out $50,000 as a death benefit.

From the perspective of the 50-year-old female, what are the values corresponding to the two events of surviving the year and not surviving?

----

Ans: -226 ; 50,000-226 = 49774

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

If a 50-year-old female purchases the policy, what is her expected value?

Using conditional probability, it is found that there is a 0.00002 = 0.002% probability that an event that occurs in this region is that of an authorized user .

Conditional Probability

\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)

In which

In this problem:

Probability of an event in this region:

Hence:

\(P(A) = 0.01\frac{1}{1000} + 0.5\frac{999}{1000} = \frac{0.01 + 0.5(999)}{1000} = \frac{499.51}{1000}\)

The probability of an event and an authorized user is:

\(P(A \cap B) = 0.01\frac{1}{1000} = \frac{0.01}{1000}\)

Hence, the conditional probability is:

\(P(B|A) = \frac{\frac{0.01}{1000}}{\frac{499.51}{1000}} = \frac{0.01}{499.51} = 0.00002\)

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Answer:

There are 210 blue counters in the bag. To find this, first use the fact that the probability of choosing a red counter from the bag is 0.3 to find the total number of counters in the bag: 0.3 = 90 / N, where N is the total number of counters. Solving for N, we find that N = 300. Since there are 90 red counters in the bag, there must be 300 - 90 = 210 blue counters in the bag.

(a) Probability of The number showing is 4 is 66.66%

(b) Probability of The number showing is an even number is 50%

(c) Probability of The number showing is greater than 5 16.66%

The area of mathematics known as probability explores potential outcomes of events, along with the likelihoods and distributions of those occurrences.

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Probability is a measure of the likelihood that an event will occur or the likelihood that something will happen. The likelihood that the coin will land with the heads side up after being tossed into the air is described using the word probability.

(a) Probability of The number showing is 4 = 4/6

                                                                          = 2/3 = 0.66 or 66.66%

(b) Probability of The number showing is an even number

= 3/6     (2, 4, 6 is even numbers)

= 1/2

= 0.5 or 50%

(c) Probability of The number showing is greater than 5 = 1/6

                                                                                             = 0.16 or 16.66%

Answer:

$519

Step-by-step explanation:

We know that the one day sale price of the ski set is $324 and the markdowns are specified.

A markdown means a reduction in price, so to find the original selling price we need to add the amount of markdown to the sale price.

The markdown of the ski set is $75 + $120 = $195

So, to find the original selling price we need to add the markdown amount to the sale price:

$324 + $195 = $519

Therefore, the original selling price of the ski set was $519

The interquartile range of the given data using R is 13.3

As per the given data,

The midterm scores of an algebra class of 20 students;

69, 84, 52, 93, 81, 74, 89, 85, 88, 63, 87, 64, 67, 72, 74, 55, 82, 91, 68, 77

We have to find the interquartile range using R.

Interquartile Range;-

The interquartile range includes the second and third quartiles or the middle half of your data set (IQR). The range gives the spread of the full data set, whereas the interquartile range gives the range of the middle half of the data set.

Interquartile range = \(Q_{3} -Q_{1}\)

\(Q_{1}\) is the lower quarter

\(Q_{3}\) is the upper quarter

\(Q_{2}\) is the median

Here,

\(Q_{2}\) = 63 +  \($\frac{87}{2}\)

\(Q_{2}\) = \($\frac{150}{2}\)

\(Q_{2}\) = 75

\(Q_{1}\) = 81 + \($\frac{74}{2}\)

\(Q_{1}\) = 77.5

\(Q_{3}\) = 74 + \($\frac{55}{2}\)

\(Q_{3}\) = 64.5

Then,

Interquartile range = \(Q_{3} -Q_{1}\) = - (64 . 5 - 77.5) = 13.3

That is,

The interquartile range for the given data set is 13.3.

1) ∠C and ∠G are supplementary while ∠A and ∠G are complementary.

2) Yes, ∠D is supplementary to ∠GAH

This is based on understanding complementary and supplementary angles.

By definition, complementary angles are two angles whose sum is equal to 90°. Meanwhile supplementary angles are those whose sum is equal to 180°.

From inspection, ∠A looks same angle with ∠G. But, for them to be complementary they have to add up to 90°. Thus;

∠A + ∠G = 90°

Since ∠A = ∠G, then ∠A = ∠G = 90/2 = 45°

Now, ∠C appears to be the remaining part of ∠G to complete a straight line.

We know that sum of angles on a straight line is 180°

Thus;

∠C + ∠G = 180°

∠C + 45° = 180°

∠C = 180° - 45°

∠C = 135°

Thus, ∠C and ∠G are supplementary while ∠A and ∠G are complementary.

For ∠D to be supplementary to ∠GAH, it means that ∠GAH must be 180° - 63° = 117°

By inspection, it looks permissible.

Thus, ∠D is supplementary to ∠GAH

Answer:

43.75 ft²

Step-by-step explanation:

Actual sizes

4/2 *5 = 10 feet

3.5/2 * 5 = 8.75 feet

Area

a = (1/2)bh

a = (1/2)(10)(8.75)

a = 43.75 ft²

answer: 28561^2in the area involves multiplying by the 4 sides of the shaded square and the shaded is the colored square.

The first quartile is the number in between the lowest number of a data set and the median. To find it, I would use a Z table as shown below

The z score that corresponds to 0.25 is -0.67 on the table above.

Using the equation of z-score below

Where x is the value we're looking for and σ and μ are the standard deviations and the mean given in the problem.

Given that the mean is 100.4 and the standard deviation is 19.7, make x the subject of the z-score formula and substitute for the mean and standard deviation as shown below

Hence, the first quartile is 87.201
