12 more than 8 times a number m

Answer:

34.134%

Step-by-step explanation:

Given :

Normal distribution ;

Mean, m = 100 ; Standard deviation, s = 10

Percentage score between 90 and 100

P(90 ≤ x ≤ 100)

Recall : Zscore = (x - m) / s

P[(90 - 100) / 10 ; (100 - 100) / 10]

P[(10/10 ; 0 / 10)]

P(Z ≤ 1) - P(Z≤0) (Using Z probability calculator)

0.84134 - 0.5

= 0.34134

= 0.34134 * 100%

= 34.134%

Question:

Two red and two blue blocks....

Answer:

[tex]P(Not\ Blue) = \frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]Red = 2[/tex]

[tex]Blue = 2[/tex]

Required

Probability of not selecting blue

First, we calculate the probability of selecting blue

[tex]P(Blue) = \frac{Blue}{Total}[/tex]

[tex]P(Blue) = \frac{2}{2+2}[/tex]

[tex]P(Blue) = \frac{2}{4}[/tex]

[tex]P(Blue) = \frac{1}{2}[/tex]

In probability:

Opposite probabilities sum up to 1 i.e.

[tex]P(Blue) + P(Not\ Blue) = 1[/tex]

This gives

[tex]\frac{1}{2} + P(Not\ Blue) = 1[/tex]

[tex]P(Not\ Blue) = 1 - \frac{1}{2}[/tex]

[tex]P(Not\ Blue) = \frac{2-1}{2}[/tex]

[tex]P(Not\ Blue) = \frac{1}{2}[/tex]

Answer:

5 loaves

Step-by-step explanation:

Dianna made several loaves of bread yesterday. Each loaf required 2 2/3 cups of flour. All together, she used 13 1/3 cups of flour. How many loaves did Dianna make?

Flour per loaf = 2 2/3 Cups of flour

Total cups of flour used = 13 1/3 cups

How many loaves did Dianna make?

Number of loaves Dianna makes = Total cups of flour used / Flour per loaf

= 13 1/3 ÷ 2 2/3

= 40/3 ÷ 8/3

= 40/3 × 3/8

= (40*3) / (3*8)

= 120 / 24

= 5 loaves

Number of loaves Dianna makes = 5

Answer:

In mathematics, a function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set. Typical examples are functions from integers to integers, or from the real numbers to real numbers.

Step-by-step explanation:

Answer:

32

Step-by-step explanation:

So since you can see that two of the sides are equal, that means the 2 angles at the bottom of the triangle are both equal to 25. Since the interior angles in a triangle always add up to 180, so it would be:

25 + 25 + 4x + 2 = 180

Solving,

52 + 4x = 180

subtract 52 from both sides

[tex]4x = 128[/tex]

divide both sides by 4

[tex]x = 32[/tex]°

hope that makes sense!

Answer:

x = 32

Step-by-step explanation:

the tic marks on the two sides of the triangle indicate they are congruent; therefore the two base angles are congruent also - each is 25°.

so, we can set up this equation to solve for 'x':  25 + 25 + 4x + 2 = 180

52 + 4x = 180

4x = 128

x = 32

Answer:

Substitute different values of x in y=3x and get corresponding y coordinates.

Substitute different values of x in y=3x and get corresponding y coordinates.Such as (0,0),(1,3),(2,6),(−1,−3),(−2,−6)

Substitute different values of x in y=3x and get corresponding y coordinates.Such as (0,0),(1,3),(2,6),(−1,−3),(−2,−6)Now, when x=−2 then y=−6 .

Answer:

$700

Step-by-step explanation:

Step one:

Given data

Regular cost of cell phone= $780

discount = 15%

tax = 5.5%

Step two

Let us compute the discounted amount

= 15/100*780

=0.15*780

=$117

hence the selling price is

=780-117

=$663

Also, the tax-deductible is

=5.5/100*663

=0.055*663

=$36.465

The total cost of the phone will be

=663+36.465

=699.465

=$700 to the nearest cent

Answer:

The solution to the quadratic equation be:

[tex]x=\frac{5}{3},\:x=-1[/tex]  

Step-by-step explanation:

Given the expression

3x² – 2x = 5

Solving with the quadratic formula

[tex]3x^2-2x=5[/tex]

subtract 5 from both sides

[tex]3x^2-2x-5=5-5[/tex]

Simplify

[tex]3x^2-2x-5=0[/tex]

For a quadratic equation of the form ax²+bx+c=0

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

For a = 3, b = -2, c = -5

[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:3\left(-5\right)}}{2\cdot \:3}[/tex]

[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \:8}{2\cdot \:3}[/tex]

Separate the solutions

[tex]x_1=\frac{-\left(-2\right)+8}{2\cdot \:3},\:x_2=\frac{-\left(-2\right)-8}{2\cdot \:3}[/tex]

solving

[tex]x_1=\frac{-\left(-2\right)+8}{2\cdot \:3}[/tex]

    [tex]=\frac{2+8}{2\cdot \:3}[/tex]

    [tex]=\frac{10}{6}[/tex]

    [tex]=\frac{5}{3}[/tex]

also solving

[tex]x_2=\frac{-\left(-2\right)-8}{2\cdot \:3}[/tex]

    [tex]=\frac{2-8}{2\cdot \:3}[/tex]

    [tex]=\frac{-6}{2\cdot \:3}[/tex]

    [tex]=\frac{-6}{6}[/tex]

     [tex]=-\frac{6}{6}[/tex]

     [tex]=-1[/tex]

Therefore, the solution to the quadratic equation be:

[tex]x=\frac{5}{3},\:x=-1[/tex]  

Answer:

There is not enough info for me to answer this.

Answer:

43

Step-by-step explanation:

Let x=lucy and y=chuck

we know that in total they found 92 arrowheads which means that

x+y=92

we also know that lucy found 6 more than chuck which means taht

x-6=y

Let's solve this through substitution

Looking at the second equation we know exactly what y is equal to in terms of x so we can plug this in (x-6) whenever we see a y in the first equation

so we have

x+(x-6)=92

solve for x and get

2x=98

x=49

Now that we know what x is equal to we can solve for y

49-6=y

y=43

This means that lucy found 49 and chuck found 43  

Answer:

I believe the answer to be 12:20 p.m.

Step-by-step explanation:

2 hours and 35 minutes + the 45 minute stop = 3 hours and 20 minutes.

From 9:00 am, 3 hours is 12:00, plus the 20 minutes left over.

Answer:

12:20 PM

Step-by-step explanation:

Simply add 35 and 45, which would give you 80. Since you know that there can only be 60 minutes in an hour, you just subtract 60 from 80, which will give you 20. all those 60 minutes (or an hour) to the 32 hours you already have. Now you have 3 hours. Now add the 20 minutes we have left over and then you have an answer of 3 hours and 20 minutes. Now add 3 hours and 20 minutes to 9 AM and you get an answer of 12:20 PM.

Answer:

3/14

Step-by-step explanation:

1 1/4 can be written as 5/4

5 5/6 can be written as 35/6

so divide (5/4)/(35/6)

= (5/4)*(6/35)

=(1/4)*(6/7)

=6/28

simplified = 3/14

Answer:

$3,072

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 32000 × 0.032 × 3 = 3072

I = $ 3,072.00

The simple interest accumulated

on a principal of $ 32,000.00

at a rate of 3.2% per year

for 3 years is $ 3,072.00.

Answer:

Yes

Step-by-step explanation:

Permutation :

nPr = n! ÷ (n - r)!

nCr = n! ÷ (n-r)!r!

11 objects taken 3 at a time :

11P3 = 11! ÷ (11 - 3)!

11P3 = 11! / 8!

11P3 = (11 * 10 * 9 )

11P3 = 990

Dividing by 3!

3! = 3*2*1 = 6

= 990 / 6

= 165

For combination :

11C3 = 11! ÷ 8!3!

11C3 = (11 * 10 * 9) / (3 * 2 * 1)

11C3 = 990 / 6

11C3
