the security system in a house has two units that set off an alarm when motion is detected. neither one is entirely reliable, but one or both always go off when there is motion anywhere in the house. suppose that for motion in a certain location, the probability that detector a goes off and detector b does not go off is 0.25, and the probability that a does not go off is 0.35. what is the probability that b goes off?

Answers

Answer 1

The probability that detector B goes off is 0.75

In this question we have been given the security system in a house has two units that set off an alarm when motion is detected.

Here, the probability that detector A will not go off is 0.35

And the probability that A will go off and B will not go off is 0.25

We need to find the probability that B goes off

The probability that detector A will go off would be,

1 - P( detector A will not go off )

= 1 - 0.35

= 0.65

And the probability that both A and B will go off would be,

= P(A will go off) - P( A will go off and B will not go)

= 0.65 - 0.25

= 0.40

Now we find the required probability.

P(B goes off) = P(both A and B will go off) + P(detector A will not go off)

                     = 0.40 + 0.35

                     = 0.75

Therefore, the required probability is 0.75

from a square cadrboard sheet, a 5cm wide strip was cut away. the area of the remaining rectangle is 266 cm. find the original dimensions of the square cardboard sheet.

Answers

Answer: S=19cm

Step-by-step explanation:

area = s^2

s(s-5)=266

s^2-5s=266

s^2-5s-266=0

(s-19)(s+14)=0

s=19cm

19 x 19 = 266

The original dimensions of the square cardboard sheet is 19 x 19.

What is Quadratic Equation?

ax² + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable, a≠0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

Given:

Let the length of each side of the original square cardboard be x cm.

After cutting off a strip of 3cm wide its dimension becomes

length = x cm and breadth= (x−5) cm

So, Area = x² - 5x

266 = x² - 5x

x² - 5x - 266= 0

x² - 19x + 14x - 266= 0

x(x - 19) + 14 (x - 19)= 0

(x- 19)( x + 14) = 0

x= 19, -14.

Hence, the original dimensions of the square cardboard sheet is 19 x 19.

16 Robert

Answers

To find the loan amount after five years, we need to calculate the compound interest on the loan. The compound interest is calculated by multiplying the principal (the initial amount borrowed) by the compound interest rate, raised to the power of the number of compounding periods. In this case, the compound interest rate is 5.75%/12 = 0.475% per month, and there are 12*5 = 60 compounding periods (12 months per year for 5 years).

The compound interest is therefore calculated as follows:

Compound interest = $1,500 * (1 + 0.475%)^60 - $1,500

= $1,725 - $1,500

= $225

So the loan amount after five years is $1,725. Therefore, the correct answer is [D] $1,725.

What is percentage?

A percentage is a figure or ratio that may be stated as a fraction of 100 in mathematics. If we need to compute the percentage of a number, divide it by the entire and multiply by 100. As a result, the percentage denotes a part per hundred. The term % refers to one hundred percent. The sign "%" represents it. To compute a percentage, divide the value by the entire amount and multiply the result by 100. (value/total value)100% is the formula for calculating percentage.

The 4th term of an AP i 6 if the um of the 8th and 9th term i -72, the common difference i

Answers

The 4th term of an AP is 6 if the um of the 8th and 9th term is -72, The 4th term of an AP is -18.

The sum of 8th and 9th term of an AP is given as -72.

We can use the formula for the sum of any n terms of an AP,

Sn = n/2[2a + (n-1)d]

Where,

a = first term

d = common difference

n = number of terms

Therefore,

-72 = 8/2[2a + (8-1)d]

-72 = 4[2a + 7d]

-18 = 2a + 7d

Subtracting 7d from both the sides,

-18 - 7d = 2a

Dividing both the sides by 2,

(-18 - 7d)/2 = a

a = -18/2 - (7d)/2

a = -9 - (7d)/2

For the 4th term of an AP,

a4 = a + (4-1)d

Arithmetic operations can be used to solve this question by using the topic of order of operations. We need to use × and - operators to get the correct answer.

How do we solve inequalities using Arithmetic operations?

Many straightforward inequalities can be resolved by adding, taking away, multiplying, or dividing both sides until the variable is all that remains. However, these factors will shift the direction of inequality: Using a negative number to multiply or divide both sides. switching the left and right sides. When resolving an inequality, you can do one of the following:

• Add the same amount to each side;

• Subtract the same amount from each side;

• Multiply or divide each side by the same positive amount. You must flip the inequality sign if you multiply or divide each side by a negative number.

Calculation:

5 x (23-18) x (8-4)=100

So we can subtract 23 from 18 where we will get 5 and by subtracting 4 from 8 you will get 4. By multiplying the numbers using × operator you will get the final answer.

the distribution of salaries of teachers is approximately normal. which measure of central tendency would be the best measure to determine the location of the center of the distribution?

Answers

The best measure of central tendency to determine the center of the distribution of teacher salaries is the mean.

The mean is the average of all values in a set and is calculated by adding up all the values and dividing them by the number of values. This measure is particularly useful for data that follows a normal distribution, as teacher salaries are likely to do.

The mean is the most commonly used measure of central tendency and is a good indicator of the center of the data set. It is also relatively easy to calculate. So mean will be the measure of the central tendency to determine the center of the distribution of teacher salaries.

r from 0 to a and θ from π/2 to π

Now the integral is

[tex]\int_{0}^{a}\int_{-\sqrt{a^2-y^2}}^{0}7x^2ydxdy[/tex] = [tex]\int_{\pi/2}^{\pi}\int_{0}^{a}7(r\cos\theta)^2(r\sin\theta)drd\theta[/tex]

P-value = 0.0384

As P-value < 0.05, reject the null hypothesis.

What is test statistic?

A statistic (a number obtained from the sample) used in statistical hypothesis testing is known as a test statistic. Usually, a hypothesis test is described in words.

A test statistic is a figure obtained from a statistical analysis. It explains how distant your observed data is from the null hypothesis, which states that there is no correlation between the variables or distinction between the sample groups.

The alternative and null hypotheses are listed below.

Lack of hypothesis H0: μ = 13

Ha: 13 Alternative Hypothesis

Statistical test, z = (xbar - mu)/(sigma/sqrt(n))

z = (11 - 13)/(8/sqrt(50))

z = -1.77

Region of Rejection

For α= 0.05, this is a left-tailed test.

Z has a critical value of -1.645.

Therefore, if z -1.645, reject H0 and accept the null hypothesis.

P-value Approach

P-value = 0.0384

As P-value < 0.05, reject the null hypothesis
