The probability that the shipment will be accepted anyway is 0.0885.

Given,

In the question:

A random sample of 150 is selected and examined for bruises, discoloration, and other defects. The whole truckload will be rejected if more than 5% of the sample is unsatisfactory. Suppose that 8% of the apples on the truck do not meet the desired standard.

To find the probability that the shipment will be accepted anyway.

Now, According to the question:

The sample size, n = 150.

The population proportion, p = 0.08.

The shipment is accepted of the sample proportion is less than 5%.

Now, to find the required probability the listed conditions to verified.

Randomization: It was stated that a random sample is chosen.

Independence: It can be supposed that the fact that a sample is satisfactory is independent of the other apple's condition.

10% condition: It can be supposed that the population size is larger than 150 (sample size).

Normality: This condition requires that np and n (1 − p) must be at least 10, so it can be verified as,

np = (150 x 0.08)

np = 12 [tex]\geq[/tex] 10

The mean of the sample proportion can be estimated as:

μ[tex]_p[/tex] = p

    = 0.08

Similarly, The standard deviation of the sample proportion can be estimated as:

σ[tex]_p[/tex] = [tex]\sqrt{\frac{p(1-p)}{n} }[/tex]

    =  [tex]\sqrt{\frac{0.08(1-0.08)}{150} }[/tex]

    =  0.02215

Thus, the sampling distribution of sample proportion can be approximated as,

p ~ N(0.08 ~ 0.0222)

The required probability is given as:

P(p < 0.05) = P (p - μ[tex]_p[/tex] /σ[tex]_p[/tex]  < 0.05 - 0.08/ 0.0222)

                  = P(Z < -1.35)

                 = 1 - P (Z < 1.35)

                  = 0.0885

Note: The probability value corresponding to the Z score is obtained from the unit normal table.

Thus, the probability that the shipment will be accepted anyway is 0.0885.

It is false that when two variables are highly correlated, a change in the value of one will cause a change in the value of another.

What is the variable of an equation?

An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable, then, is a symbol denoting a number whose value is unknown. In this case, x + 5 = 10. "X" in this case is a variable.

The fact that two variables are correlated does not mean that one causes the other.

False

If there is a causal relationship between two variables, then variables are correlated but it is not always true that if variables are correlated then there is a causal relationship.

What is the newborn's weight?

A newborn's body weight is referred to as birth weight. At birth, babies of European descent typically weigh between 2.5 and 4.5 kilograms, or about 3.5 kilograms on average. South Asian and Chinese babies typically weigh 3.26 kg.

Here,

Babies born to nonsmokers typically weighed between 1,000 and 5,000 grams. Babies of smokers typically ranged in weight from 500 to 4500 grams.

However, there are some obvious disparities between the two groups' typical ranges of birth weights. Since there are fewer newborns in the lower weight groups, over half of neonates among nonsmokers (56 out of 115, 48.7%) had birth weights between 3,000 and 4,000 grams.

A sample of at least 68 bulbs is needed to be 96% confident that our sample mean will be within 10 hours of the true mean.

What do you mean by sampling?

Sampling is the process of choosing the group from which you will actually collect data for your study. For instance, you could interview a sample of 100 students if you were examining the viewpoints of students at your university. With the help of sampling, you can test a statistical hypothesis on the features of a population.

According to the question,

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha =\frac{1-0.96}{2} =0.02[/tex]

Now, we have to find z in the Z table as such z has a p value of [tex]1-\alpha[/tex].

So it is z with a p value of [tex]1-0.02=0.98[/tex], so z= 2.055

Now, find the margin M as such

M = z*σ/√n

In which σ is the standard deviation of the population and n is the size of the sample.

In this problem, we have that:

σ = 40, M = 10,

M = z*σ/√n

[tex]10=2.055*\frac{40}{\sqrt{n} } \\10\sqrt{n}=82.2\\ \sqrt{n}=8.22\\ n=67.6[/tex]

A rectangle is a quadrilateral that has congruent opposite sides and each of the 4 interior angles of the rectangle are right angles.

(A) The lengths of the sides of the  rectangle are;

Top side; √(6² + 2²)

Opposite to the top √(6² + 2²)

Left side; √(3² + 1²)

Right side; √(3² + 1²)

The lengths of the opposite side are the same

Therefore;

The opposite sides are congruent

(B) The lengths of the diagonals are as follows;

Length of first diagonal=  √((2 - 1)² + (1 - 8)²) = √(1² + 7²) = √(50) = 5·√2

Step-by-step explanation:

The correct option regarding how many times stronger the wave amplitude A of the earthquake was than the standard wave Ao is given by:

A = 39,811 Ao.

To find the ratio of A and Ao, which states how many times a earthquake measuring R in the Richter scale was stronger than the standard intensity Ao, we have to solve the following logarithmic function:

R = log(A/Ao)

The Richter scale of the earthquake in this problem is given as follows:

R = 4.6.

Hence the ratio of the measures is obtained as follows:

4.6 = log(A/Ao)

The power of 10 is the inverse function of the logarithm, hence if it is applied to both sides of the equation, then we can isolate the ratio A/Ao as follows:

A/Ao = 10^4.6

A/Ao = 39,811.

Applying cross multiplication, the ratio is given as follows:

A = 39,811 Ao.

The dimension of the rectangle of maximum area that you can enclose with the string is 12.5 x 12.5

n let x = the length of one side of the rectangle and y = the length of the other side of the rectangle.

The area is:

A = xy

and the perimetere is the string of length 50 cm

50 = 2(x + y) Solve this in terms of y. Divide both sides by 2.

25 = x + y By Subtract x from both sides.

25-x = y Now substitute this into the equation for the area.

A = x (25 - x) Simplify.

A = 25x - x²

the general form of quadratic equation: ax² + bx + c

x is given by -b/2a

Here the equation is A = -x² + 25x

, a = -1, b = 25, and c = 0

so we can find the x-coordinate of the vertex by -25/2(-1) = 12.5

So the length (x) of the rectangle must be 12.5 cm to get the maximum area.

But what about the width (y)?

Since the perimeter is 50 cm and this is twice the (length + width), the (length + width) is 25 cm, so the width is 25 cm - the length.

x + y = 25

12.5 + y = 25

y = 12.5

So, we end up with x (the length) = 12.5 cm and y (the width) = 12.5 cm.

And this, of course, is a square whose sides are 12.5 cm

If the perimeter were k cm,

2(x + y) = k

x + y = k/2

x + x = k/2 (as x = y)

x = k/4

x = k/4, y = k/4

Therefore,  the dimension of the rectangle of maximum area that you can enclose with the string is 12.5 x 12.5

The probability that  4 creature cards is pulled is 1/14 and the probability that 3 land cards and 1 creature card is pulled is 4/35

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here there are 4 land cards and 6 creature cards

thus selecting four cards at random from 10 cards is  ¹⁰C₄=210

and the event of selecting 4 creature cards from a total of 6 cards is ⁶C₄ =15

Therefore probability of pulling 4 creature cards is = 15/210

                                                                                     = 1/14

The probability of pulling 3 land cards and 1 creature cards is    

= ⁴C₃ × ⁶C₁   /  ¹⁰C₄

= 4/35

Hence 1/14 and 4/35 are the respective probabilities.
