a jar of 25 lollipops in a clinic has 7 that are grape, 10 cherry, and 8 orange. If a nurse selects 4 lollipops randomly, what is the probability that they will all be grape?

Answers

Answer 1

The probability of grape is 7/25 or 28%. The total is alway the denominator of the fraction and the amount of each type is the numerator. So the fraction is 7/25. To find the percent you multiple the fraction by 4 because 25*4=100 so the percent is 28% because 7*4=28.

Expression 1; If your friend bikes 1.5 miles home from school each day for 4 weeks, they bike a total of - miles in that time period. The math I did was multiply 5 by 4 to get 20 school days in 4 weeks, and multiplied 1.5 by 20 to get 30 miles biked in 4 weeks.
Expression 2; If you bike 3.25 miles home from school each day, using the same math shown in the previous expression, substituting 1.5 for 3.25. Using that math, you would bike 65 miles in 4 weeks.

A shoe store is having a sale where every pair of shoes cost $15. If you buy more than five pairs, you get a 10% discount. How much will it cost for seven pair of shoes?

Answers

7(15) = 105

10% off means u r paying for 90%...
0.9(105) = 94.50 <=

Multiply the amount of shoes being bought (7) by the price of one pair of shoes (15):

7(15) = $105 with NO discount

If you have 10% off that means that you will be paying 90%. Multiply 90% or 0.9 by the cost of the seven shoes:

0.9(105) = 94.50

You will pay $94.50 for the seven pairs of shoes.

Well to find this first you will divide the area by the length.
If you can use a calculator just put 11.875/4.75 which gives you as your width 2.5.
If you can't then change them into irregular fractions so...
11 7/8 --> 95/8
4 3/4 --> 19/4
Then divide them
95/8 / 19/4

Luis made some trail mix .He mixed 4 2/3 cups of popcorn ,1 1/4 cups of peanuts ,1 1/3 cups of raisins ,and 3/4 cup of sunflower seeds.He gave 5 of his friends an equal amount of trail mix each.How much did each friend get?

Answers

so you have to add all the fractions together and then divide by five. When dealing with mixed fractions i like to add the whole numbers first, then add the fractions:
4 2/3, 1 1/4, 1 1/3, 3/4
the whole numbers: 4 + 1 + 1 = 6
then we are left with 2/3, 1/4, 1/3, 3/4
add the ones with common denominators together to make it easiest: 2/3 + 1/3 = 3/3 = 1 (another whole number! add it to 6 to get 7)
now we are left with 1/4 + 3/4 = 4/4 = 1 (another whole number! add it to 7 to get 8)
Now we know there are 8 cups of trail mix all together divide it by 5 friends and you get 8/5. 5 goes into 8 once with three left over so you get 1 3/5 cups per friend.

True or False? The point-slope form of a line is y + y1 = m(x + x1), where m is the slope and (x1, y1) is a point on the line. It's false right?

Answers

False.

Point-slope form is: y-y1=m(x-x1)

They used sums instead of differences...

Answer:

False

The correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .

Step-by-step explanation:

The formula for the point slope form passing through the point (a,b) is given by.

[tex](y-b)=m (x-a)[/tex]

Where m is the slope .

As given in the question.

m is the slope and (x1, y1) is a point on the line.

Thus the point slope form becomes

[tex](y-y1)=m (x-x1)[/tex]

Therefore the correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .

Consider the following sets. U = {ordered pairs on a coordinate plane} A = {ordered pair solutions to y = x} B = {ordered pair solutions to y = 2x} Which ordered pair satisfies A ∩ B?

Answers

Answer:

(0,0)

Step-by-step explanation:

We have,

U = { (x,y) : x,y belong to real numbers }

A = { (x,y) : (x,y) is a solution of y=x }

B = { (x,y) : (x,y) is a solution of y=2x }

We need to find the ordered pair (x,y) that belong to A[tex]\bigcap[/tex]B.

Let, (x,y) belong to A[tex]\bigcap[/tex]B

i.e. (x,y) belong to A and (x,y) belong to B

i.e. y = x and y = 2x

i.e. x = 2x

i.e. x = 0

Now, substitute x= 0 in any of the equation say y = x, we get y = 0.

Hence, the ordered pair satisfying A[tex]\bigcap[/tex]B is (0,0).

For a set U, The ordered pair satisfies A ∩ B is mathematically given as

x = 0, y = 0 (0,0)

Which ordered pair satisfies A ∩ B?

Question Parameter(s):

U = {ordered pairs on a coordinate plane}

A = {ordered pair solutions to y = x}

B = {ordered pair solutions to y = 2x}

if (x,y) belongs to AnB

y = x and y = 2x

x = 0

In conclusion, subsituting we have

y = x and y = 2x

y = 0

The total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

What is Expression?

An expression is combination of variables, numbers and operators.

Given,

The baker pays $0.80 per pound for sugar

The baker pays $1.25 per pound for butter.

We need to write expression that shows how much the baker will spend if he buys 6 pounds of butter and 20 pounds of sugar.

Let x be the pounds for sugar

x be the pounds for butter

20x+6y=Total

As x=0.80 and y=1.25

20(0.80)+6(1.25)

16+7.5

23.5

Hence, the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

This sequence represents the diameters of circles used to create an art project: 2.5 cm, 3.1 cm, 3.7 cm, 4.3 cm Let f(n) represent diameter in centimeters and n the term number in the sequence. Which equation represents the sequence of diameters?

Answers

ANSWER

The expression that represent the sequence of diameters is,
[tex]f(n) = 0.6n + 1.9[/tex]

EXPLANATION

The terms in the sequence are,

[tex]2.5,3.1,3.7,4.3[/tex]

The first term is
[tex]a = 2.5[/tex]

The common difference is

[tex]d = 3.1 - 2.5 = 0.6[/tex]

The formula for the nth term is given by,

[tex]f(n) = a + (n - 1)d[/tex]

We substitute the values in to the formula to get,

[tex]f(n) = 2.5+ (n - 1)0.6[/tex]

We expand the parenthesis to obtain,

[tex]f(n) = 2.5 + 0.6n - 0.6[/tex]

We rearrange to obtain,

[tex]f(n) = 0.6n + 2.5- 0.6[/tex]

We simplify to get,

[tex]f(n) = 0.6n + 1.9[/tex]

Answer:

[tex]f(n) = 1.9 +0.6n[/tex]

Step-by-step explanation:

The nth term of the arithmetic sequence is given by:

[tex]a_n = a_1+(n-1)d[/tex] ....[1]

where

[tex]a_1[/tex] is the first term

d is the common difference and n is the number of terms.

Here, f(n) represent diameter in centimeters and n the term number in the sequence.

Given the sequence represents the diameters of circles used to create an art project:

2.5 cm, 3.1 cm, 3.7 cm , 4.3 cm

This sequence is an arithmetic sequence with

[tex]a_1[/tex] = 2.5 and d = 0.6

Since,

3.1-2.5 = 0.6,

3.7-3.1 = 0.6

4.3-3.7 = 0.6

Substitute the given values in [1] we have;

[tex]f(n) =2.5+(n-1)(0.6)[/tex]

Using distributive property, [tex]a\cdot (b+c) = a \cdot b+ a\cdot c[/tex]we have;

[tex]f(n) = 2.5+0.6n-0.6[/tex]

Simplify:

[tex]f(n) = 1.9 +0.6n[/tex]

Therefore, the equation represents the sequence of diameters is, [tex]f(n) = 1.9 +0.6n[/tex]

(09.01) The function below shows the number of car owners f(t), in thousands, in a city in different years t: f(t) = 0.25t2 − 0.5t + 3.5 The average rate of change of f(t) from t = 2 to t = 6 is ______ thousand owners per year.

Answers

The average rate of change is:

r=(f(b)-f(a))/(b-a), where a and b are the beginning and end of the interval.

So in this case:

r=(.25(6^2)-.5(6)+3.5-.25(2^2)+.5(2)-3.5)/(6-2)

r=1.5

So the average rate of change of car owners is 1.5 thousand owners per year.

Answer: The average rate of change of f(t) from t = 2 to t = 6 is 1.5 thousand owners per year.

Step-by-step explanation:

Given: The function below shows the number of car owners f(t), in thousands, in a city in different years t:

[tex]f(t) = 0.25^2 - 0.5t + 3.5[/tex]

Now,

[tex]f(2) = 0.25(2)^2 - 0.5(2) + 3.5=3.5\\\\= f(6) = 0.25(6)^2-0.5(6)+ =9.5[/tex]

Now, the average rate of change of f(t) from t = 2 to t = 6 is given by :-

[tex]k=\dfrac{f(6)-f(2)}{6-2}\\\\=\dfrac{9.5-3.5}{4}=1.5[/tex]

Hence, the average rate of change of f(t) from t = 2 to t = 6 is 1.5 thousand owners per year.
