The weight of oranges growing in an orchard is normally distributed with a mean weight of 6.5 oz. and a standard deviation of 1.5 oz. Using the empirical rule, determine what interval would represent weights of the middle 99.7% of all oranges from this orchard.

chicken total cost

3 * 3.50 = $10.5

ground total cost

1.5 * 4.25 = $6.38

Answer:

$50

Step-by-step explanation:

Change 250 to a decimal:

250/100 = 2.50

multiple the price by this decimal to find the new price:

$20 x 2.50 = $50

Measuring with inches will give us inches. If you look at a ruler, inches are about a pinky finger. If 12 inches together, it is called a yard. If 3 feets are together, it is known as a yard foot

Answer: $33.48

Step-by-step explanation:

Given that:

Capacity of car tank =. 16 gallons

Gallons of already filled = 6.6 gallons

Amount left of tank capacity = 16 - 6.7

Amount left of tank capacity = 9.3 gallons

Cost of gas per gallon = $3.60

Hence, amount spent in gas will be

Amount left of tank capacity * cost per gallon of gas

= 9.3 gallons * $3.60

= $33.48

Total amount spent on gas = $33.48

Answer:

BC = 5

Step-by-step explanation:

Since it is an isosceles, it is the base angles that are equal

Since the base angles are equal, then the sides facing these angles are equal

Mathematically, what we are supposed to have as equals should be AB and BC since they are the sides facing the base angles

Thus, BC should be 5

Answer:

[tex]\sqrt{12}[/tex] units

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the other leg, then

x² + 2² = 4²

x² + 4 = 16 ( subtract 4 from both sides )

x² = 12 ( take the square root of both sides )

x = [tex]\sqrt{12}[/tex] units

which can be simplified to 2[tex]\sqrt{3}[/tex] units , if required.

Determine the domain

The domain of a function are the values of x that makes the function to be defined.

From the given function, we can see that no single value of x will make the function become undefined.

Hence, the domain is:

x = (-∞, +∞)

In other words, the domain implies that all real numbers.

Hence:

Option (A) answers the question.

Answer:

Step-by-step explanation:

The pentagon is dilated 3 units to the left and 3 units vertically down and the rule is ( x , y ) → ( x + 3 , y - 3 )

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the pentagon be represented as A

Now , the dilated pentagon is represented as A'

Now , the center of dilation is the origin O ( 0 , 0 )

where it is dilated 3 units to the left

So , the x coordinate is changed to x + 3

And , dilated vertically downward by 3 units

So , the y coordinate is changed to y - 3

Hence , the dilated pentagon is ( x , y ) → ( x + 3 , y - 3 )

Answer:

NQ=15

Step-by-step explanation:

To solve this we can use the side-splitter theorem.

NS/SR=NP/PQ

PQ=x since we do not know it's value

now to subsitute the given/known values.

12/78=2/x

solve for x using cross multiplication.

12x=156

x=13

PQ=13

NQ= PQ+NP

NP=2

NQ=13+2

NQ=15

The length of NQ is 15.

Step-by-step explanation:

I suggest to make a table

x        y

( )      ( )

( )      ( )

and on each section put the points on the correct input and output

once you do that you want to see how much you need to add or subtract to get to the other input or output

For example

if i have ( 5, 10) and ( -5, -10)

I would make a table that looks like this with each of the inputs and outputs.....

x       y

5      10

-5      -10

From 10 to -10 you need to subtract 20

from 8 to -8 you need to subtract 10

so y/x

-20/-10

2 negative numbers make a positive so...

your slope will be 2

So with any numbers that they give you, use what I showed u

An exceptional answer to the question provided would be, y = 6x + 2

Step-by-step explanation:

Alex buys x oranges and Bobbie buys x + 2 oranges. Together they buy 2x + 2 oranges.

$4.20 / $0.21 = 20 oranges.

2x + 2 = 20

2x = 18

x = 9

Hence the value of x is 9.

Answer:

x=9

Step-by-step explanation:

The total number of oranges purchased is x + x+2 =  2x+2

They cost 21 cents each

(2x+2) *.21

This is equal to 4.20

(2x+2) *.21 =4.20

Divide each side by .21

(2x+2) *.21/.21 =4.20/.21

2x+2 = 20

Subtract 2 from each side

2x+2-2 =20-2

2x= 18

Divide by 2

2x/2 =18/2

x =9

Answer:

Torrance must purchase 5 packages of snack bags and 6 packages of juice boxes.

Step-by-step explanation:

Given that:

Snack bags come in packages of 12.

Juice bags come in packages of 10.

To find:

Fewest number of packages of each product so that there are same number of snack bags and juice boxes.

Solution:

Number of snack bags when 1 package is bought = 12

Number of snack bags when 2 package is bought = 24

Number of snack bags when 3 package is bought = 36

Number of snack bags when 4 package is bought = 48

Number of snack bags when 5 package is bought = 60

Number of snack bags when 6 package is bought = 72

Number of juice bags when 1 package is bought = 10

Number of juice bags when 2 package is bought = 20

Number of juice bags when 3 package is bought = 30

Number of juice bags when 4 package is bought = 40

Number of juice bags when 5 package is bought = 50

Number of juice bags when 6 package is bought = 60

Number of juice bags when 7 package is bought = 70

We can see that when 5 packages of snack bags are bought and 6 packages of juice bags are bought, 60 bags of each are bought.

This can be found by finding the LCM as well.

LCM of 10 and 12 is 60.

It means we need to buy 60 bags of each item.

And we can easily find the number of packages for each.

Number of packages of snack bags to be bought = [tex]\frac{60}{12} =5[/tex]

Number of packages of juice bags to be bought = [tex]\frac{60}{10} = 6[/tex]

Torrance must purchase 5 packages of snack bags and 6 packages of juice boxes.

Answer:

$0.78 per apple

Step-by-step explanation:

First, find the price of the bag with the coupon:

9.33 - 2.31

= 7.02

Then, find the price per apple by dividing this by 9, since there are 9 apples in the bag:

7.02/9

= 0.78

So, with the coupon, the price per apple is $0.78

Answer:

The average speed of the athlete for the entire competition is approximately 21.23 km/hr

Step-by-step explanation:

The given parameters of the athlete performance in the triathlon are;

The length the athlete swims = 750 m = 0.75 km

The time the athletes spends swimming = 15 minutes = 0.25 hours

The speed with which the athlete cycles = 40 km/hr.

The time the athletes spends while cycling = 30 minutes = 0.5 hours

The distance the athlete ran = 5 km

The average speed with which the athlete ran = 3 m/s = 10.8 km/hr.

The formula for average speed, s is Average speed = Total distance/(Total time)

The distance, ∑d, the athlete covered in the entire competition is given as follows;

∑d = 0.75 km + 0.5 hr. × 40 km/hr. + 5 km = 0.75 km + 20 km + 5 km = 25.75 km

The distance, ∑t, the athlete spends in the entire competition is given as follows;

∑t = 0.25 hr. + 0.5 hr. + 5 km/(10.8 km/hr.) = 0.25 hr. + 0.5 hr. + 0.463 hr. ≈ 1.213 hr.;

Therefore;

The average speed of the athlete for the entire competition, s = ∑d/∑t = 25.75 km/(1.213 hr.) ≈ 21.23 km/hr.

The values of k will be:

[tex]k=-1,\:k=3[/tex]

Step-by-step explanation:

Let the expression of polynomial P be

[tex]P\left(x\right)=3x^2-4kx-4k^2[/tex]

Let the expression if the polynomial Q be

[tex]\:Q\left(x\right)=\:\left(x+2\right)\:[/tex]

Plug in Q(x) = 0

0 = x+2

x = -2

As (x+2) is a factor of 3x²-4kx-4k²

substitute x = -2 in the the polynomial

3x²-4kx-4k² = 0

[tex]3\left(-2\right)^2-4k\left(-2\right)-4k^2\:=0[/tex]

[tex]12+8k-4k^2=0[/tex]

Write in the standard form ax²+bx+c = 0

[tex]-4k^2+8k+12=0[/tex]

Factor out common term -4

[tex]-4\left(k^2-2k-3\right)=0[/tex]

Factor k²-2k-3: (k+1)(k-3)

[tex]-4\left(k+1\right)\left(k-3\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]k+1=0\quad \mathrm{or}\quad \:k-3=0[/tex]

solving k+1=0

k+1 = 0

k = -1

solving k-3=0

k-3=0

k = 3

Thus, the values of k will be:

[tex]k=-1,\:k=3[/tex]
