Can someone help me?

Answer:

The answer is A

Step-by-step explanation:

105+90=5x-70

195+70=5x-70+70

\( \frac{265}{5} = \frac{5x}{5} \)

53=x and then when you insert to in the formula 5(53)-70 you get 195

and 105+90 is also equal to 195

Youre welcome!

The two non-right angles in a right angled triangle balance each other out because the right angle already takes up 90 degrees of the triangle's 180 total angles. We refer to two angles as complementing each other when their sums equal 90 degrees.

The right angle, or 90°, is always one angle. The hypotenuse is the side with the 90° angle opposite. The longest side is always the hypotenuse. The sum of the other two inner angles is 90 degrees. Base and perpendicular are the names of the other two sides that are close to the right angle. The Pythagorean Theorem is a triangle formula.

Answer:

3/10

Step-by-step explanation:

To find how much remains, you need to find 1/2 of 3/5 which is 1/2 * 3/5. To multiply the two fractions, multiply the two numerators and multiply the two denominators to get 3/10. Thus, 3/10 of the candy bar remains.

Hope this helps :)

Answer:

3/10

Step-by-step explanation:

To find half of 3/5 first set up a multiplication problem:

(1/2)*(3/5)

Now multiply the numerators by each other and the denominators by each other:

(1*3)/(2*5)

The result of this multiplication is: 3/10

The numerator of the repeated-measures t-statistic is the difference between the means of two related groups, while the numerator of the single sample t-statistic is the difference between the sample mean and the population mean.

In a repeated-measures t-test, you compare the means of two related groups, typically in a pretest-posttest design or when participants are measured under two different conditions. The numerator for the repeated-measures t-statistic is calculated as:

Numerator (Repeated-Measures) = Mean_Difference - 0

where Mean_Difference is the mean of the differences between the two related groups.

In a single sample t-test, you compare the mean of a single sample to a known population mean. The numerator for the single sample t-statistic is calculated as:

Numerator (Single Sample) = (Sample_Mean - Population_Mean)

In summary, the numerators differ in that the repeated-measures t-statistic considers the differences between two related groups, while the single sample t-statistic compares a sample mean to a population mean.

Step-by-step explanation:

The Smith family is looking to rent a large truck for their upcoming move. With Rose's Moving, they would pay $40 for the first day plus $6 per additional day. With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day. Before deciding on which company to use, Mrs. Smith wants to find out what number of additional days would make the two choices equivalent with regards to cost. How many additional days would that be?

Let the number of additional days = x

With Rose's Moving, they would pay $40 for the first day plus $6 per additional day.

40 + 6x

With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day.

90 + x

Comparing both

40 + 6x = 90 + x

6x - x = 90 - 40

5x = 50

x = 50/5

x = 10

The number of additional days = 10 days

Answer:

The theoretical probability is greater than the empirical probability.

Step-by-step explanation:

Therefore, Morris is traveling at a rate of 70.33 feet per second, which is more accurate than 50 miles per hour.

To determine which measurement is more accurate, we need to convert both rates to the same unit. Since Aneesha's rate is given in miles per hour and Morris's rate is given in feet per second, we need to convert one of them to match the other.

First, let's convert Aneesha's rate to feet per second:

Aneesha's rate = 50 miles per hour

1 mile = 5280 feet

1 hour = 3600 seconds

50 miles per hour = (50 * 5280) feet per (1 * 3600) seconds

= 264,000 feet per 3,600 seconds

= 73.33 feet per second (rounded to two decimal places)

Now let's calculate Morris's rate, which is 3 feet per second less than Aneesha's rate:

Morris's rate = 73.33 feet per second - 3 feet per second

= 70.33 feet per second (rounded to two decimal places)

So the polygon has 22 sides.

A polygon's sides are made up of straight line segments that are joined end to end. As a result, the line segments of a polygon are referred to as sides or edges. The place where two line segments meet is known as the vertex or corners, and an angle is generated as a result. A triangle with three sides is an example of a polygon.

The sum of the interior angles of a polygon can be calculated using the formula:

(n-2) * 180 = sum of the interior angles

Where n is the number of sides of the polygon.

We know that the sum of the interior angles is 20*180, so we can substitute this into the formula:

(n-2) * 180 = 20 * 180

Solving for n, we get:

n = (20 * 180) / 180 + 2

n = 20 + 2

n = 22

So the polygon has 22 sides.

There is a 44.37% chance that none of the suspects will be falsely accused of lying based on the lie detector test.

The process of lie detector with the help of probability :-

Assuming the lie detector test is accurate, the probability of showing a positive reading (indicating a lie) is 0.15, and the probability of showing a negative reading (indicating truth) is 0.85.

If all six suspects are telling the truth, the probability of observing no positive readings in the sample can be calculated as follows:

P(no positive readings) = P(negative reading for suspect 1) * P(negative reading for suspect 2) * P(negative reading for suspect 3) * P(negative reading for suspect 4) * P(negative reading for suspect 5) * P(negative reading for suspect 6)

= 0.85 * 0.85 * 0.85 * 0.85 * 0.85 * 0.85

= 0.4437053125

Therefore, the probability of observing no positive readings if all suspects are telling the truth is approximately 0.4437 or 44.37%.

This means that there is a 44.37% chance that none of the suspects will be falsely accused of lying based on the lie detector test. However, it is important to note that the accuracy of lie detector tests is often questioned, and they are not considered reliable evidence in many legal systems.

The rejection region for the alternative hypothesis µ > 6,700 is located in the right or upper tail.

In hypothesis testing, the rejection region is the range of sample values that leads to the rejection of the null hypothesis. The alternative hypothesis in this case states that the population mean (µ) is greater than 6,700. To determine the rejection region, we need to consider the critical value or significance level (α) chosen for the test.

The rejection region for the alternative hypothesis µ > 6,700 is located in the right or upper tail of the distribution. This means that if the sample mean falls in this region, it provides strong evidence against the null hypothesis. The specific values that define the rejection region depend on the chosen significance level. Typically, the rejection region is determined by comparing the test statistic (such as a t-value or z-value) to the critical value obtained from a statistical table or calculator. If the test statistic falls in the rejection region, the null hypothesis is rejected in favor of the alternative hypothesis, indicating evidence for a population mean greater than 6,700.

The term that refers to the fact that the distance between two or more points is equal is "equidistant".

In geometry, the concept of equidistance is important when dealing with circles, which are sets of points that are equidistant from a single point called the center. This property is what allows circles to be defined in terms of their radius, which is the distance between the center and any point on the circle.

Equidistance is also important in other areas of mathematics and science. For example, in physics, equidistant points can be used to define a plane or surface that is perpendicular to a given line or axis. This is useful in many applications, such as designing electronic circuit boards or constructing buildings.

The concept of equidistance is not limited to mathematics and science, however. It can also be applied in everyday life. For instance, if you are planning a road trip and want to visit several destinations that are equidistant from your starting point, you can use this information to help plan your route and estimate your travel time.
