Answer:

The running club has 35 members

Step-by-step explanation:

Let

x ----> the total members of the running club

we know that

The total members of the running club multiplied by 5/7 plus 6 must be equal to 31 people

so

[tex]\frac{5}{7}x+6=31[/tex]

Solve for x

[tex]\frac{5}{7}x=31-6[/tex]

[tex]\frac{5}{7}x=25[/tex]

[tex]x=25(7)/5[/tex]

[tex]x=35\ members[/tex]

therefore

The running club has 35 members

Probability of a male having a blood circulation problem, given he's a smoker, is approximately 0.6667.

Step 1:

Identify the given probabilities:

Let [tex]\( P(A) \)[/tex] be the probability that a randomly chosen male has a blood circulation problem, which is [tex]\( 0.25 \)[/tex].

Let [tex]\( P(B|A) \)[/tex] be the probability that a male is a smoker given that he has a blood circulation problem, and it's twice the probability of being a smoker given not having a blood circulation problem.

Step 2:

Calculate [tex]\( P(B|\neg A) \)[/tex]:

Since males with blood circulation problems are twice as likely to be smokers as those without, \( P(B|\neg A) \) is half of [tex]\( P(B|A) \)[/tex], which is [tex]\( \frac{1}{2} \)[/tex].

Step 3:

Apply Bayes' theorem:

[tex]\[ P(A|B) = \frac{P(B|A) \times P(A)}{P(B)} \][/tex]

Step 4:

Calculate \( P(B) \):

[tex]\[ P(B) = P(B|A) \times P(A) + P(B|\neg A) \times P(\neg A) \][/tex]

Step 5:

Substitute values into Bayes' theorem and solve:

[tex]\[ P(A|B) = \frac{(2 \times P(B|\neg A)) \times P(A)}{(2 \times P(B|\neg A)) \times P(A) + P(B|\neg A) \times (1 - P(A))} \]\[ P(A|B) = \frac{(2 \times \frac{1}{2}) \times 0.25}{(2 \times \frac{1}{2}) \times 0.25 + \frac{1}{2} \times (1 - 0.25)} \]\[ P(A|B) = \frac{0.25}{0.25 + 0.125} \]\[ P(A|B) = \frac{0.25}{0.375} \]\[ P(A|B) \approx 0.6667 \][/tex]

Thus, the probability that a male has a blood circulation problem, given that he is a smoker, is approximately 0.6667.

Answer:

j = (h-4) / k

Step-by-step explanation:

Unless there is more information given about this question somewhere else in the assignment, I'm assuming you are being asked to solve this equation for j.

If so, then its just a matter of rearranging the equation so that it is in the form

j = (expression containing other variables)

(h-4) / j = k   (multiply both sides by j)

(h-4) = jk  (divide both sides by k)

j = (h-4) / k

Answer:

720 shares

Step-by-step explanation:

Find 60% of 1,200, to figure out how many shares Jillian has.

Change 60% to decimal

0.6

Multiply with the total shares

0.6 x 1,200 = 720

720 shares

Jillian owns 720 shares in a catering corporation.

The percentage is defined as a ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have to determine 60% of 1,200, to figure out how many shares Jillian has.

Convert 60% into a decimal

⇒ 0.6

Multiply with the total shares

⇒ 0.6 × 1200

⇒  720

Hence, Jillian owns 720 shares in a private catering corporation.

Answer:

Mixture 1 and Mixture 2 will create the same color

Step-by-step explanation:

we know that

If two mixtures create the same color, then the proportion of the painting in the mixtures must be the same

Let

x ----> the ounces of a red paint in the mixture

y ----> the ounces of a blue paint in the mixture

Verify the proportion of the paints in each mixture

Mixture 1) x=2, y=1

[tex]\frac{2}{1}=2[/tex]

Mixture 2) x=7, y=3.5

[tex]\frac{7}{3.5}=2[/tex]

Mixture 3) x=4.5, y=2

[tex]\frac{4.5}{2}=2.25[/tex]

Mixture 4) x=5.5, y=2.5

[tex]\frac{5.5}{2.5}=2.2[/tex]

therefore

Mixture 1 and Mixture 2 will create the same color, because have the same ratio

Answer:

Mixture 1 and Mixture 2

Step-by-step explanation:

It is given that Raj is mixing different colors (blue and red) of paint to make a new color.

If two mixtures have same ratio of red and blue color, then that will create the same color.

The ratio of red and blue color in each mixture is shown below:

Mixture 1: [tex]\frac{Red}{Blue}=\frac{2}{1}=2:1[/tex]

Mixture 2: [tex]\frac{Red}{Blue}=\frac{7}{3.5}=\frac{2}{1}=2:1[/tex]

Mixture 3: [tex]\frac{Red}{Blue}=\frac{4.5}{2}=\frac{9}{4}=9:4[/tex]

Mixture 4: [tex]\frac{Red}{Blue}=\frac{5.5}{2.5}=\frac{11}{5}=11:5[/tex]

From the above calculation it is clear that the ratio of red and blue color in mixture 1 and mixture 2 is same.

Therefore, Mixture 1 and Mixture 2 will create the same color.

Answer:

72.5 miles/hour

Step-by-step explanation:

When we say "miles per hour" in English this just is simply the question "If Bailey drove for only one hour, how far did she go?". Now mathematically we can find this very easily by simply dividing 290 by 4, which is equal to 72.5. So Bailey travels 72.5 miles every hour.  

If it is confusing about why we do this, think about splitting up 290 miles evenly between 4 hours, how many miles does each hour 'get'. Each would 'get' 72.5 miles. So for every hour Bailey drives she travels 72.5 miles which is the same as saying that she drove at 72.5 miles per hour.

Hope this helps!

Answer:

3, 6, 12, 24

Step-by-step explanation:

This is a recursive formula which allows the next term in a sequence to be found from the previous term in the sequence

Given

[tex]a_{n}[/tex] = 2[tex]a_{n-1}[/tex] with a₁ = 3, then

a₂ = 2 × a₁ = 2 × 3 = 6

a₃ = 2 × a₂ = 2 × 6 = 12

a₄ = 2 × a₃ = 2 × 12 = 24

Thus the first 4 terms are 3, 6, 12, 24

Answer:

B.[tex]3,6,12,24[/tex]

Step-by-step explanation:

We are given that

[tex]a_n=2a_{n-1}[/tex]

[tex]a_1=3[/tex]

We have to find the first four terms of G.P

Substitute n=2

[tex]a_2=2a_1=2(3)=6[/tex]

Substitute n=3

[tex]a_3=2a_2=2(6)=12[/tex]

Substitute n=4

[tex]a_4=2a_3=2(12)=24[/tex]

Hence, the first four terms of G.P are  given by

[tex]3,6,12,24[/tex]

Option B is true.

Answer:

The value of b is 12.9 cm

The value of a is 15.3 cm

Step-by-step explanation:

see the attached figure to better understand the problem

Find the value of b

we know that

in the right triangle ABC

The function sine of angle of 40 degrees is equal to divide the opposite side to the angle of 40 degrees (AC) by the hypotenuse (AB)

so

[tex]sin(40\°)=AC/AB[/tex]

Solve for AC

[tex]AC=(AB)sin(40\°)[/tex]

substitute the given value

[tex]AC=(20)sin(40\°)[/tex]

[tex]AC=12.9\ cm[/tex]

therefore

The value of b is 12.9 cm

Find the value of a

we know that

in the right triangle ABC

The function cosine of angle of 40 degrees is equal to divide the adjacent side to the angle of 40 degrees (BC) by the hypotenuse (AB)

so

[tex]cos(40\°)=BC/AB[/tex]

Solve for BC

[tex]BC=(AB)cos(40\°)[/tex]

substitute the given value

[tex]BC=(20)cos(40\°)[/tex]

[tex]BC=15.3\ cm[/tex]

therefore

The value of a is 15.3 cm

Answer:

C. [tex]h(x)=x-3[/tex]

Step-by-step explanation:

We have been given a function [tex]f(x)=x+3[/tex]. We are asked to find the inverse of the given function.

First of all, we will replace [tex]f(x)[/tex] by y as:

[tex]y=x+3[/tex]

Now, we will interchange x and y variables as:

[tex]x=y+3[/tex]

Solve for y:

[tex]x-3=y+3-3[/tex]

[tex]x-3=y[/tex]

Switch sides:

[tex]y=x-3[/tex]

Therefore, the inverse function for the given function would be [tex]h(x)=x-3[/tex].

6 x 6 x 6

Step-by-step explanation:

Six to the third power means to multiply 6 by itself 3 times.

The standard exponential function is expressed as y = ab^x. The value for the simplified form of 6 to the third power is 216

The standard exponential function is expressed as y = ab^x

Given the following parameters

6 to the third power

This can be expressed as 6^3

6^3 = 6 * 6 * 6

6^3 =36 *6

6^3 = 216

Hence the value for the simplified form of 6 to the third power is 216
