The answer is 6.868 10

The number of times that diameter of cell G is larger than diameter of Cell H is; 46 × 10¯¹ times

We are given;

Now, to find how much more larger the diameter of cell G is than diameter of cell H, we will divide the diameter of cell G by the diameter of cell H to get;

(4.21 × 10^(-3))/(9.2 × 10^(-4)) = 4.6

Thus,diameter of cell G is 4.6 times larger than diameter of Cell H

Answer:

z=9

Step-by-step explanation:

we are given: 2/3z=6

we need to find what z is by itself

6 is 2/3rds of what the value of z is.

to find z, we need to multiply both sides by 3/2 (the reciprocal of 2/3z, to make the coefficient of 1)

3/2*2/3z=6*3/2

z=9

hope this helps :)

z = 9

Step-by-step explanation:

2/3 . z = 6

2z/3 = 6

Multiple all terms by the same value to eliminate fraction denominator,

3 x 2z/3 = 3 x 6

2z = 18 ( 3,3 got cancelled)

Divide both sides of the equation by the same term,

2z/2 = 18/2

On Simplify,

z = 9.

*(2,2 gets cancelled and 18/2 = 9)

Answer:

50-6= 54

54÷4= 13.5

editing for clarity.

first you subtract the 6 from the 50 to find out what the "4 times a number" came to.

in this case, 50-6, which equals 54.

then, you divide the 54 by 4 to get 13.5.

so, the whole math problem would be

4 times 13.5 plus 6 equals 50.

Answer:

Answer:

To determine the explicit rule for the arithmetic sequence of 20.5, 16, 11.5, 7, 2.5, ..., the following logical reasoning must be performed:

20.5 - 16 = 4.5

16 - 11.5 = 4.5

11.5 - 7 = 4.5

7 - 2.5 = 4.5

Thus, the explicit rule of the arithmetic sequence is that the numbers are gradually subtracted by 4.5, with which the next number of said sequence would be -2.

Answer:

0.35 or 35%

Step-by-step explanation:

The probability that any seed will germinate is said to be 0.65 (or 65%) in the question. This means that the remaining percentage is the probability that the randomly selected seed will not germinate. This is because there is only two possible outcomes to that given scenario, which is it will germinate or not. Meaning that the remaining percentage/probability is that it will not germinate

1 - 0.65 = 0.35 or 35%

Answer:

[tex]9\sqrt{3}[/tex]

Step-by-step explanation:

The right triangle on the right is a special right triangle: a 30-60-90 triangle

30-60-90 corresponds with the angle measures on the triangle

the sides on a 30-60-90 relate to the angle opposite of it

30 ⇒x       60 ⇒ x[tex]\sqrt{3}[/tex]      90 ⇒ 2x

27 is opposite to the 60° angle

[tex]\frac{x\sqrt{3}} {\sqrt{3}} =x[/tex]   [tex]\frac{27}{\sqrt{3}}[/tex]  simplify [tex]\frac{27}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex]     [tex]\frac{27\sqrt{3} }{3}[/tex] = [tex]9\sqrt{3}[/tex]

The required value of altitude y is 9 units which is determined by the geometric theorem.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

As we know that the geometric theorem states that h = √(ab),

where h is the altitude of a right triangle, a and b are the segments formed when the altitude divides the hypotenuse of a right triangle.

We have to determine the value of altitude y

As per the given figure, a = 3, and b = 27

Substitute the values  in the formula, and we get

y = √(3 × 27)

y = √81

y = 9

Therefore, the measure of y = 9.

Answer:

a) 0.1151 = 11.51% probability that an individual distance is greater than 210.00 cm.

b) 0.883 = 88.3% probability that the mean for 20 randomly selected distances is greater than 197.80 cm.

c) The distribution of the population is normal, which means that the sample size does not need to exceed 30.

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.

The overhead reach distances of adult females are normally distributed with a mean of 200 cm and a standard deviation of 8.3 cm.

This means that [tex]\mu = 200, \sigma = 8.3[/tex]

a. Find the probability that an individual distance is greater than 210.00 cm.

This is 1 subtracted by the pvalue of Z when X = 210. So

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

[tex]Z = \frac{210 - 200}{8.3}[/tex]

[tex]Z = 1.2[/tex]

[tex]Z = 1.2[/tex] has a pvalue of 0.8849

1 - 0.8849 = 0.1151

0.1151 = 11.51% probability that an individual distance is greater than 210.00 cm.

b. Find the probability that the mean for 20 randomly selected distances is greater than 197.80 cm

Now [tex]n = 20, s = \frac{8.3}{\sqrt{20}} = 1.8559[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 197.8. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{197.8 - 200}{1.8559}[/tex]

[tex]Z = -1.19[/tex]

[tex]Z = -1.19[/tex] has a pvalue of 0.117

1 - 0.117 = 0.883

0.883 = 88.3% probability that the mean for 20 randomly selected distances is greater than 197.80 cm.

c. Why can the normal distribution be used in part​ (b), even though the sample size does not exceed​ 30?

The distribution of the population is normal, which means that the sample size does not need to exceed 30.

Answer:

-64

Step-by-step explanation:

The computation of the 10th term of the progression is shown below:

The 3rd term is -9

A_n = a + (n - 1)d

-9 = a + (3 - 1)d

-9 = a + 2d

-9 - 2d = a

Now the 7th term is -29

A_n = a + (n - 1)d

-29 = a + (7 - 1)d

-29 = a + 6d

Put the a value to the above equation

-29 = -9 - 2d + 6d

-29 + 9 = 4d

-20 = 4d

d = -5

Now

-9 - 2d = a

-9 - 2(-5) = a

-9 - 10 = a

a = -19

Now finally the 10th term of the progression is

= a + (n - 1)d

= -19 + (10- 1)-5

= -19 -45

= -64
