True proportion

I hope this helps!

==============================================

Work Shown:

kx+7 = 4

kx+7-7 = 4-7 .... subtract 7 from both sides

kx = -3

kx/k = -3/k .... divide both sides by k

x = -3/k

The value of k cannot be zero. As the steps show, we are following PEMDAS in reverse to undo each operation to help isolate x. Subtraction is the opposite of addition, and division is the opposite of multiplication.

Answer:

Yes, a triangle can be formed

Step-by-step explanation:

Look

a=5

b=8

c=11

The rule is U need to add the 2 smallest sides

a+b>c

if a+b=c then this is not a triangle

Now look

5+8=13

13 is greater than 11

13>11 so this is a triangle

2 smallest sides are greater than biggest side

Answer:

See explantion

Step-by-step explanation:

Given

[tex]Rosa = 314[/tex]

[tex]Brett = 18\ more[/tex]

The question is incomplete as what is required is missing from the question. I'll solve on a general term

A possible question is: Determine the total number of votes by Brett

We have that:

[tex]Brett = 18\ more[/tex]

So:

[tex]Brett = 18 + Rosa[/tex]

Substitute 314 for Rosa

[tex]Brett = 18 + 314[/tex]

[tex]Brett = 332[/tex]

Another possible question is: Determine the total number of voters.

This is done by:

[tex]Total = Brett + Rosa[/tex]

[tex]Total = 332 + 314[/tex]

[tex]Total = 646[/tex]

Answer:

53.15≤x≤67.89

Step-by-step explanation:

The formula for calculating confidence interval is expressed as;

CI = xbar±(z×s/√n)

xbar is the sample mean

z is the z score at 90% CI

s is the standard deviation

n is the sample size

Given

xbar = $60.52

s = $23.29

n = 27

z = 1.645

Substitute into the formula

CI = xbar±(z×s/√n)

CI = 60.52±(1.645×23.29/√27)

CI = 60.52±(1.645×23.29/5.196)

CI = 60.52±(1.645×4.482)

CI = 60.52±7.373

CI = [60.52-7.373, 60.52+7.373]

CI = [53.15, 67.89]

Hence the 90% confidence interval for the mean repair cost for the refrigerators is 53.15≤x≤67.89

Answer:

[tex]Ratio = 2 : 1[/tex]

Step-by-step explanation:

Given

[tex]Population = 13[/tex] --- Boys & Girls

Required

Determine the ratio of the kitten ears to the tails

A kitten has 1 tail and 2 ears.

Assume each individual got 1 kitten each

This implies that,

[tex]Number\ of\ tails= 1 * 13[/tex]

[tex]Number\ of\ tails= 13[/tex]

[tex]Number\ of\ ears= 2* 13[/tex]

[tex]Number\ of\ ears= 26[/tex]

The ratio of ears to tail is then calculated as follows:

Ratio = Number of ears : Number of tails

This gives

[tex]Ratio = 26 : 13[/tex]

Divide by 13

[tex]Ratio = 26/13 : 13/13[/tex]

[tex]Ratio = 2 : 1[/tex]

Answer:

It is  reasonable to conclude that species diversity in location 1 is greater than species diversity in location 2.

Step-by-step explanation:

From the question we are told that

      The   95% confidence interval for the difference between species diversity in the two locations  is  [tex]0.223 < \mu_1 - \mu_2 < 1.361[/tex]

Now this 95%  confidence interval tell us that there a 95%  confidence that the true difference between species diversity in the two locations is within the interval

For the value of the 95% confidence interval given we see that both  the upper limit and the lower limit is greater than zero which tell us that the true difference will also be greater than zero

Hence

  it is  reasonable to conclude that species diversity in location 1 is greater than species diversity in location 2

Answer:

The type of driver

Step-by-step explanation:

The term known as '' response variable'' is use in describing a variable that changes when you alter an examination or a test. Just like its name implies, it is the ''response'' that one gets when the other variable that is the Explanatory Variable are being altered.

In this question, the golfer will have to be changing the type of drivers that she is using in order to be able to know whether these changes in drivers will increase her game performance. Hence, the Explanatory Variable is the type of driver in which the golfer changes which is being use to define the performance of the golfer.

Note: Consider 84 instead of 83 because the value of x is a decimal value of 83 which is not possible.

Given:

Compound ratio of 7:5 and 8:x is 84:60.

To find:

The value of x.

Solution:

Compound ratio of 7:5 and 8:x is 84:60.

[tex]\dfrac{7}{5}\times \dfrac{8}{x}=\dfrac{84}{60}[/tex]

[tex]\dfrac{7\tims 8}{5\times x}=\dfrac{84}{60}[/tex]

[tex]\dfrac{56}{5x}=\dfrac{84}{60}[/tex]

By cross multiplication, we get

[tex]56\times 60=84\times 5x[/tex]

[tex]3360=420x[/tex]

Divide both sides by 1420.

[tex]\dfrac{3360}{420}=x[/tex]

[tex]8=x[/tex]

Therefore, the value of x is 8.

Answer:

2 and 16/25

Step-by-step explanation:

first: change 0.64 into a fraction which is 64/100

second: simplify by dividing by four which is:

64/4 = 16

100/4 = 25

so...

2.64 = 2 16/25

HOPE THIS HELPS :)

Answer:

2 and 16/25 OR 66/25

Step-by-step explanation:

As a mixed fraction, 2.64 is 2 and 64/100 because you have 2 whole 100s and a 64/100. Simplify 64/100 to 16/25 (divide both 64 and 100 by 4) and you're left with 2 and 16/25.

In improper form, you have 264/100. Simplify that (divide 264 and 100 by 4) and you're left with 66/25.

Answer:

45/2 or 22.5 or 22 1/2

Step-by-step explanation:

When dividing fractions you take the second number (2/9) and flip it over (reciprocal)

5   ÷  2/9  becomes 5 x 9/2

5 x 9/2 =

45/2 or 22.5 or 22 1/2

Answer:

The value is [tex]P(8 < X < 10 ) = 0.8186[/tex]

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = 10 .0[/tex]

     The standard deviation is  [tex]\sigma = 1[/tex]

Generally the probability that a single reading is between 8 and 10 is mathematically represented as

      [tex]P(8 < X < 10 ) = P( \frac{8 - 10 }{ 1} < \frac{X - \mu }{ \sigma } < \frac{10 - 10 }{1} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

=>    [tex]P(8 < X < 10 ) = P( -2 < Z< 1 )[/tex]

=>   [tex]P(8 < X < 10 ) = P( Z< 1 ) - P( Z < -2 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1 and  -2  is  

       [tex]P( Z< 1 ) = 0.84134[/tex]

and

     [tex]P( Z < -2 ) = 0.02275[/tex]

=>   [tex]P(8 < X < 10 ) = 0.84134 - 0.02275[/tex]

=>   [tex]P(8 < X < 10 ) = 0.8186[/tex]

Answer:

Brain travelled 687.68 from the cliff.

Step-by-step explanation:

Given that:

Height of the cliff = 520

Base of the cliff = 450

The distance will form the hypotenuse of right angled triangle.

Pythagorean theorem states square of hypotenuse of right angled triangle is equal to the sum of squares of base and height of triangle.

Using pythagorean theorem;

a = 520, b=450, c = hypotenuse

[tex]a^2+b^2=c^2\\(520)^2+(450)^2=c^2\\270400+202500=c^2\\472900=c^2\\c^2=472900[/tex]

Taking square root on both sides

[tex]\sqrt{c^2}=\sqrt{472900}\\c=687.68[/tex]

Hence,

Brain travelled 687.68 from the cliff.

Step-by-step explanation:

Answer:

[tex]f(0) = 14[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \left \{ {{|x - 8| + 6 \ x<4} \atop {15\ x\ge 4}} \right.[/tex]

Required

Find f(0)

From the piecewise function, we have the following as values of f(x):

[tex]f(x) = |x - 8| + 6[/tex]

If [tex]x < 4[/tex]

[tex]f(x) = 15[/tex]

If [tex]x \ge 4\\[/tex]

f(0) implies that [tex]x =0[/tex] and [tex]0<4[/tex]

So, we make use of the first function, which is:

[tex]f(x) = |x - 8| + 6[/tex]

Substitute 0 for x in [tex]f(x) = |x - 8| + 6[/tex]

[tex]f(0) = |0 - 8| + 6[/tex]

[tex]f(0) = |- 8| + 6[/tex]

[tex]|-8| = 8[/tex]

So, the expression becomes

[tex]f(0) = 8 + 6[/tex]

[tex]f(0) = 14[/tex]

Hence, the value of f(0) is 14

Answer:

The cost for each pound of jelly beans and each pound of almonds is $1.25 and $2.25  respectively.

Step-by-step explanation:

Let the cost for each pound of jelly beans and each pound of almonds be x and y respectively.

ATQ,

For 5 pounds of jelly beans and 3 pounds of almonds, the total cost is $13.

5x+3y = 13 ...(1)

For 2 pounds of jelly beans and 6 pounds of almonds, the total cost is $16.

2x+6y = 16

x + 3y = 8 ....(2)

Subtract equation (2) from (1)

5x+3y-(x + 3y)= 13-8

4x = 5

x = 5/4

x = $1.25

Put the value of x in equation (2) as follows :

1.25 + 3y = 8

3y = 8-1.25

y =$2.25

Hence, the cost for each pound of jelly beans and each pound of almonds is $1.25 and $2.25  respectively.
