The percentage of people that have a blood glucose level between 100 and 125 is 21.945%

From the question, the given parameters about the distribution are

Mean value of the set of data = 85

Standard deviation value of the set of data = 25

The actual data values = 100 and 125

The z-score of the data value is calculated using the following formula

z = (x - mean value)/standard deviation

For x = 100, we have:

Substitute the given parameters in the above equation

z = (100 - 85)/25 = 0.6

For x = 125, we have:

Substitute the given parameters in the above equation

z = (125 - 85)/25 = 1.6

The percentage between 100 and 125 is then calculated as:

P(100 < x < 125) = P(z < 1.6) - P(z < 0.6)

From the z table of probabilities, we have;

P(100 < x < 125) = 0.9452 - 0.72575

This gives

P(100 < x < 125) = 0.21945

Express as percentage

P(100 < x < 125) = 21.945%

Hence, the percentage is 21.945%

answer:

(1,3)

step-by-step explanation:

desmos.

The value of x will be equal to 7 for the given slope of 2 for the line.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.

Given that the points (4, -3) and (x, 3) lie on the same straight line. The slope of the line is 2.

The slope of the line is calculated by the formula,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

2 = ( 3 + 3 ) / ( x - 4)

2(x-4) = 6

2x - 8 = 6

2x = 8 + 6

2x = 14

x = 14 / 2

x = 7

Therefore, the value of x will be equal to 7 for the given slope of 2 for the line.

0.1875 is  the probability of having a daughter .

Describe probability using an example?

Let X = No. of sons

n = 5 and p = 0.5, because probability of having son and daughter is same.

X follows Binomial distribution with parameter n and p. Then its pmf is,

P(X= x) = \binom{n}{x}p^xq^{(n-x)} \ \ \ \ \ x = 0,1,----5

Now,

P(X= 5) = \binom{5}{5}(0.5)^5 (0.5)^{(5-5)} \\ \\ \\ P(X= 5) = 0.03125

Probability of haveing at least four sons

P(X\ge4) = P(X=4) +P(X=5) \\\\ P(X\ge4) = 0.15625 + 0.03125 \\\\ P(X\ge4) = 0.1875

The mean and standard deviation of this sampling distribution is 1 cm and 0.033 cm, respectively.

The sample mean is the arithmetic mean of all the samples of processor chips. The mean of the sample group is known as the sample mean.

Let X denote the multiple random samples of 35 processor chips and each of which represents the size of the processor chips.

Let 'x' be the sample mean of all the random samples X which represents the size of the processor chips.

The mean of the size of processor chips= μ =1 cm

The mean of the sampling distribution x of sample means is equal to the mean of the sizes of the processor chips μ

Mean of sampling distribution x  = mean of the size of the processor chips μ

⇒ x = μ

   x = 1 cm

The mean of this sampling distribution is 1 cm.

The standard deviation is the amount of variation among the set of values. It is the measure of the dispersion of values in the data set.

The size of the processor chips has a standard deviation of 0.2 cm so σ = 0.2 cm

Let 'x' be the standard deviation of random samples X of the size of processor chips.

Number of random multiple samples of processor chips, n =35

The standard deviation of this sampling distribution can be calculated by using the below formula;

x = σ/[tex]\sqrt{n}[/tex]

Substituting the value of \sigma as "0.2" cm and the value of "n" as 35 in the above formula, we get;

x = 0.2/√35

x = 0.033 cm

The standard deviation of this sampling distribution is 0.033 cm.

Step-by-step explanation:

The coordinates of the midpoint M for the line segment AB are (-1/2, -2).

As per the stated values;

Th end points of the line segment AB are given as;

A(−5, 1) = (x1, y1)

B(4,−5) = (x2, y2)

The formula for the evaluation of the coordinates of the mid point is-

Mid point - M(x, y)

x = (x1 + x2)/ 2

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

y=4/3x+4

3y=-2x-6

Rewrite the equations in the system of equations as follows:

So, we have the following representation

y = 4/3x + 4

3y = -2x - 6

Next, we plot the graph of the system of equations

In this case, the point of intersection of the equations represent the solution to the system

From the graph, the lines intersect at (-3, 0)

Answer:

[tex]\sf \dfrac{1}{2}-\dfrac{1}{8}=\dfrac{\boxed{4}}{8}-\dfrac{1}{8}=\dfrac{\boxed{3}}{\boxed{8}}[/tex]

Step-by-step explanation:

When adding or subtracting fractions that have different denominators, first rewrite the fractions as equivalent fractions with the same denominator.  To do this, find the lowest common multiple (LCM) of the denominators.

The given subtraction is:

[tex]\sf \dfrac{1}{2}-\dfrac{1}{8}[/tex]

The LCM of the denominators 2 and 8 is 8.  Therefore, we need to rewrite the first fraction as an equivalent fraction with 8 as its denominator.  To do this, multiply its numerator and denominator by 4:

[tex]\implies \sf \dfrac{1}{2} \times\dfrac{4}{4}=\dfrac{4}{8}[/tex]

Therefore:

[tex]\implies \sf \dfrac{1}{2}-\dfrac{1}{8}=\dfrac{4}{8}-\dfrac{1}{8}[/tex]

To subtract fractions with the same denominator, simply subtract the numerators. (The denominator stays the same).

[tex]\implies \sf \dfrac{1}{2}-\dfrac{1}{8}=\dfrac{4}{8}-\dfrac{1}{8}=\dfrac{4-1}{8}=\dfrac{3}{8}[/tex]

Final solution

[tex]\sf \dfrac{1}{2}-\dfrac{1}{8}=\dfrac{\boxed{4}}{8}-\dfrac{1}{8}=\dfrac{\boxed{3}}{\boxed{8}}[/tex]

The rate of the passenger train is 60mph.

We know that,

Speed = Distance / Time

Time = Distance / Speed

s = speed of passenger train

speed of freight train = (s - 20)

T = 240 / s

T = 160 / (s-20)

240 / s = 160 / (s-20)

240(s - 20)/s(s - 20) = 160s/s(s - 20)

240(s - 20)/s(s - 20) - 160s/s(s - 20) = 0

240(s - 20) - 160s = 0s(s - 20)

240s - 4800 - 160s = 0

80s - 4800 = 0

80s = 4800

The values of x and y if the mean and median are equal are:

x = 7

y = 8.

The mean is the total sum of the values in a data set divided by the number of values of the data set.

The median of a data set is the center value when the data distribution is ordered.

Given the ordered data set as, 4, 6, x, y, and 10.

The center value is x. Therefore, the median of the data set is x.

The mean of the data = (4 + 6 + x + y + 10)/5

The mean of the data = (20 + x + y)/5

The mean and the median are equal, therefore:

(20 + x + y)/5 = x

20 + x + y = 5x

20 + y = 5x - x

20 + y = 4x

The value of x cannot be less than 6, if x = 7, we woud have:
