Answer:

L = (14x+33) inches.

Step-by-step explanation:

We know that,

1 feet = 12 inches

For example,

2 feet = 12(2) inches

Now, the length of one board is (x+3) feet

The length of second board is (2x-3) inches

We can convert length into inches as follows :

l = (x+3) feet

l= (x+3)(12) inches

l = 12x+36 inches

It means, total length,

L = 12x+36 inches + (2x-3) inches

L = (14x+33) inches.

Question Help Of 515515 samples of seafood purchased from various kinds of food stores in different regions of a country and gen

Setler79 [48]

Answer:

(0.5848 ; 0.6552)

We are confident that about 58% to 66% of sea foods in the country are Mislabelled.

No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.

Step-by-step explanation:

Sample size, n = 51

p = 0.62

1 - p = 1 - 0.62 = 0.38

n = 515

Confidence level = 90% = Zcritical at 90% = 1.645

Confidence interval = (p ± margin of error)

Margin of Error = Zcritical * sqrt[(p(1-p))/n]

Margin of Error = 1.645 * sqrt[(0.62(0.38))/515]

Margin of Error = 1.645 * 0.0214

Margin of Error = 0.035203

Lower boundary = (0.62 - 0.035203) = 0.584797

Upper boundary = (0.62 + 0.035203) = 0.655203

(0.5848 ; 0.6552)

We are confident that about 58% to 66% of sea foods in the country are Mislabelled.

No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.

Sandy has 27 roses, 9 daisies, and 18 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number

AlekseyPX

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers

Step-by-step explanation:

We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 27 are: 1, 3, 9, 27

Then the greatest common factor is 9.

The greatest number of flowers that could be in a bouquet is 9 flowers

What is an equation of the line that passes through the point (5, 4) and is parallel to

weqwewe [10]

Answer & Step-by-step explanation:

When two lines are parallel, their slopes are the same. To find the slope of the given equation, convert to slope-intercept form:

$y=mx+b\\\\$

m is the slope
b is the y-intercept, which is the value of y when the value of x is zero
x and y are the corresponding coordinate points (x,y)

$6x-5y=15$

Solve for y. Subtract 6x from both sides:

$6x-6x-5y=15-6x\\\\-5y=-6x+15$

Divide both sides by -5:

$\frac{-5y}{-5} =\frac{-6x}{-5} +\frac{15}{-5} \\\\y=\frac{6}{5}x-3$

The slope is $\frac{6}{5}$ .

Now you need to make an equation in point-slope form:

$y-y_{1}=m(x-x_{1})$

m is the slope
$x_{1}$ and $y_{1}$ are the coordinate points

Insert known values:

$y-4=\frac{6}{5}(x-5)$

You can use this equation, or you can convert to slope-intercept form by solving for y:

Use the distributive property:

$y-4=\frac{6}{5} x-6$

Add 4 to both sides:

$y-4+4=\frac{6}{5}x-6+4\\\\ y=\frac{6}{5}x-2$

What is the imagine point of (-1,-5) after a translation left 1 unit and up 4 units?

Katena32 [7]

Answer:

-2, -1

Step-by-step explanation:

So moving left would affect the x-axis.

Left would move it to the negatives so -1 - 1 = -2.

Moving up would affect the y-axis.

Up would move towards the positive so -5 + 4 = -1.

-2, -1
