Answer:

B : 10 cm^3

Step-by-step explanation:

L x W x H = V

4cm x 2cm x 1 1/4 (1.25) = 10cm^3

1 1/4 = 4 x 1 = 4 + 1 = 5/4 = 1.25

Hope this helps!

Answer:

x = 3

Step-by-step explanation:

The angle is a right angle = 90 degrees

17x + 7 + 9x + 5 = 90°

26x + 12 = 90

        -12    -12

26x = 78

/26    /26

x = 3

Answer:

a) The mean is 0.7 and the standard deviation is 0.1033.

b) 99.11% probability that the average number of moths in 40 traps is greater than 0.4.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

When traps are checked periodically, the mean number of moths trapped is only 0.7, but some traps have several moths. The distribution of moth counts is discrete and strongly skewed, with standard deviation 0.8.

This means that [tex]\mu = 0.7, \sigma = 0.8[/tex]

A) What are the mean and standard deviation of the average number of moths x in 60 traps?

60 traps means that [tex]n = 60[/tex]

By the Central Limit Theorem

Mean [tex]\mu = 0.7[/tex]

Standard deviation [tex]s = \frac{0.8}{\sqrt{60}} = 0.1033[/tex]

The mean is 0.7 and the standard deviation is 0.1033.

B) Use the central limit theorem to find the probability (±0.01) that the average number of moths in 40 traps is greater than 0.4.

40 traps means that [tex]n = 40[/tex]

Mean [tex]\mu = 0.7[/tex]

Standard deviation [tex]s = \frac{0.8}{\sqrt{40}} = 0.1265[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 0.4. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.4 - 0.7}{0.1265}[/tex]

[tex]Z = -2.37[/tex]

[tex]Z = -2.37[/tex] has a pvalue of 0.0089

1 - 0.0089 = 0.9911

99.11% probability that the average number of moths in 40 traps is greater than 0.4.

Answer:

1. 135°

2. 114°

3. 118°

4. 81°

Step-by-step explanation:

Let "x" represent the measure of the indicated angle in each problem.

1. x = 135° (corresponding angles theorem)

2. x = 180° - 66° (same-side interior angles theorem)

x = 114°

3. x = 118° (alternate interior angles theorem)

4. x = 81° (alternate exterior angles theorem)

Answer and Step-by-step explanation:

Half of them should be plain, so 46 plain bagels .

This is because the first set was split evenly, so that must mean this set should be split evenly as well.

Half of 92 is 46.

Answer:

1.5 moles

Step-by-step explanation:

number of moles = no. of particles / Avagadro number

therefore, number of moles. = 9.033 * 10^23 / 6.022 * 10^23

therefore, no. of moles = 1.5

There are 1.5 moles in 9.033 * 10^23 Lithium atoms.

Step-by-step explanation:

x is less than -10

x is greater than or equal to 25

Answer:

The negative part of the solution set is ignored, because you cannot produce a negative number of phones.

The company has at least an 80% success rate if the next 25 or more phones that are assembled work.

Because the company has already made 10 phones and 7 are not working, if the next 25 phones work, the 35th phone puts the company at its goal of 80% or more.

Answer:

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].

Step-by-step explanation:

First, we decompose the number given on statement by applying prime numbers in ascending order. We see that 200 is an even number, therefore, we infer that smallest prime number within is 2.

1) [tex]\frac{200}{2} = 100[/tex] (Even number)

2) [tex]\frac{100}{2} = 50[/tex] (Even number)

3) [tex]\frac{50}{2} = 25[/tex] (Even number)

4) [tex]\frac{25}{5} = 5[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

5) [tex]\frac{5}{5} = 1[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

Now, we construct the prime factorization using exponential notation:

[tex]200 = 2^{3}\times 5^{2}[/tex]

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].
