Answer:

67

Step-by-step explanation:

Let x be the first integer.

Therefore, the six consecutive integers are:

If the sum of the six consecutive integers is 387 then:

⇒ x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 = 387

⇒ 6x + 15 = 387

⇒ 6x + 15 - 15 = 387 - 15

⇒ 6x = 372

⇒ 6x ÷ 6 = 372 ÷ 6

⇒ x = 62

To find the sixth number, substitute the found value of x into the expression for the sixth number:

⇒ x + 5 = 62 + 5 = 67

The 99% confidence interval for the true mean lifespan of the product is, [12.128, 13.872].

What is standard deviation?

The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range.

Given: A toy maker claims his best product has an average lifespan of exactly 18 years.

A skeptical product evaluator asks for evidence (data) that might be used to evaluate this claim.

The product evaluator was provided data collected from a random sample of 35 people who used the product.

Using the data, an average product lifespan of 13 years and a standard deviation of 2 years was calculated.

As sample size is large we will use z value to calculate confidence Interval 99% confidence Interval is

{x bar} Z_({1 - alpha/2}) (s/√{n})

13\ 2.576* 2/ √13

(12.128, 13.872).

Step-by-step explanation:

The amount of  grape juice that you need to mix with 15 over 4 quarts of sparkling water is 15/8 quarts

Given that,

The amount of Sparkling water is 15/4 quarters

To find : The amount of grape juice that you need to mix with 15 over 4 quarts of sparkling water

Sparkling water measuring 1 1/2 quarters is required for the recipe. This can be expressed as the improper fraction 3/2 (since 1 whole equals 2/2 and 2/2 plus 1/2 equals 3/2).

We used 5/2 times as much sparkling water as the recipe called for, or 15/4 quarts (15/4 gallons). This implies that we would also use 5/2 times as much grape juice, or 5/2(3/4) = 15/8.

As a result, you need to combine 15 over 4 quarters of sparkling water with 15/8 quarts of grape juice.

If we had a 10-year expected prepayment horizon then Option 1 is preferred less expense and if we had a 5-year expected prepayment horizon then Option 2 is preferred less expense.

In the given question, as a borrower, we have the option to choose between two to 30-year, monthly-payment loans: 7% interest rate with 3 points, versus 7.5% interest with one-half point.

If we assume the pricipal loan amount as $100,000 based on the two option need to monthly instalements for 30 years & the equivalent amount for the respective points.

Under mortgage loan, 3 points on $100,000 is equal to $3,000 and for 1.5 points would be $1500.

Formula for calculating the monthly instalments would be

[tex]\text{EMI} = P\times \frac{r}{12}\times\left [ \frac{(1+r/12)^n}{(1+r/12)^n- 1} \right ][/tex]

where P is Principal , r is rate of interest, n = time period in months.

Using the above said formula we can compute EMI for both the options with interest rates as 7% and 7.5% respectively.

(a) We have to find which loan option would you choose if we had a 10-year expected prepayment horizon.

If repayment is 10 years then EMI under both the options would be:

Option 1: Interest rates as 7%

[tex]\text{EMI} = 100,000\times \frac{7}{1200}\times\left [ \frac{(1+7/1200)^{120}}{(1+7/1200)^{120}- 1} \right ][/tex]

EMI = $1187.02

We can respond to both questions in the following problem using the EMI calculated and the comparable amounts for the respective options.

The total price for each option is as follows.

The value of seaweed height that divides the bottom 30%  from the top 70% is 8.96 cm.

What is a Normal distribution in statistics?

Data in a normal distribution are symmetrically distributed and have no skew. The majority of values cluster around a central region, with values decreasing as one moves away from the center. In a normal distribution, the measures of central tendency (mean, mode, and median) are all the same.

Given data:

X: height of seaweed.

       X~N (μ;σ²)

       μ= 10 cm

       σ= 2 cm

We have to find the value of the variable X that separates the bottom 0.30 of the distribution from the top 0.70

              P(X ≤ x) = 0.30

              P(X ≥ x) = 0.70

Now by using the standard normal distribution,

we have to find the value of Z that separates the bottom 0.30 from the top 0.70 and then use the formula

        Z = (X - μ)/σ

translates the Z value to the corresponding X value.

           P(Z ≤ z) = 0.30

In the body of the table look for the probability of 0.30 and reach the margins to form the Z value. The mean of the distribution is "0" so below 50% of the distribution you'll find negative values.

                  z= -0.52

Now you have to clear the value of X:

        Z= (X - μ)/σ

        X= (Z * σ) + μ

       X = (-0.52 * 2) + 10

         = 8.96

hence, the value of seaweed height that divides the bottom 30%  from the top 70% is 8.96 cm.

The linear function which represents the line is y = - 3x + 14.

What is Point slope form?

Point slope form is used to represent a straight line using its slope and a point on the line. It means that the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point-slope form.

Main body:

y - y1 = m (x - x1)

where, (x, y) is a random point on the line and m is the slope of the line.

The given point-slope equation is

y + 1 = - 3 (x - 5)

By further calculation

y + 1 = -3x + 15

y = -3x + 15 - 1

y = -3x + 14

Therefore, the linear function which represents the line is y = - 3x + 14.
