Answer: 0.9974

Step-by-step explanation:

Let X be the random variable that follows the normal distribution \.

If mean ([tex]\mu[/tex]) = 10 and standard deviation ([tex]\sigma[/tex]) =1

then, the probability of selecting a number between 7 and 13 = [tex]P(7<X<13)[/tex]

[tex]=P(\dfrac{7-10}{1}<\dfrac{X-\mu}{\sigma}<\dfrac{13-10}{1})[/tex]

[tex]=P(-3<z<3)[/tex]                     [Since [tex]z=\dfrac{X-\mu}{\sigma}[/tex]]

[tex]=P(z<3)-P(z<-3) \ \ \ [P(z_1<Z<z_2)=P(Z<z_2)-P(Z<z_1)]\\\\= P(z<3)-(1-P(z<3))\ \ \ [P(Z<-z)=1-P(Z<z)]\\\\=2P(z<3)-1\\\\=2(0.9987)-1\ \ [\text{By p-value table}]\\\\= 0.9974[/tex]

Hence, the probability of selecting a number between 7 and 13 is 0.9974.

Answer:

30,031 is not a prime, is a composite number. Integer prime factorization, as a product of prime factors: 30,031 = 59 x 509.

Step-by-step explanation:

Let's learn by having an example, take number 220 and build its prime factorization.

0) We need the list of the first prime numbers, ordered from 2 up to, let's say, 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. Prime numbers are the building blocks of the composite numbers' prime factorization process.

1) Start by dividing 220 by the first prime number in our list, 2 (start with the smallest prime number). We could have skipped the division by 2 if our number were an odd number, ie. 221.

220 ÷ 2 = 110; remainder = 0 => 220 is divisible by 2 (2 | 220) => 2 is a prime factor of 220. => 220 = 2 × 110.

2) Divide the result of the previous operation, 110, by 2, again:

110 ÷ 2 = 55; remainder = 0 => 110 is divisible by 2 (2 | 110) => 2 is once again a prime factor of 220 => 220 = 2 × 2 × 55.

3) Divide the result of the previous operation, 55, by 2, again:

55 ÷ 2 = 27 + 1; remainder = 1 => 55 is not divisible by 2.

4) Move on, divide 55 by the next prime number, 3 (notice that the sum of digits of 55 is 5 + 5 = 10 is not divisible by 3, so 55 is not divisible by 3):

55 ÷ 3 = 18 + 1; remainder = 1 => as we already said, 55 is not divisible by 3.

5) Divide 55 by the next prime number, 5:

55 ÷ 5 = 11; remainder = 0 => 55 is divisible by 5 (5 | 55) => 5 is yet another prime factor of 220 => 220 = 2 × 2 × 5 × 11.

6) Notice that the remaining number, 11, is also a prime number, so we've got already all the prime factors of 220.

7) Conclusion, 220 prime factorization: 220 = 2 × 2 × 5 × 11.

This can be written in a condensed form, in the exponent notation: 220 = 22 × 5 × 11.

Answer:

[tex]Slope = 1.57[/tex]

Step-by-step explanation:

Given

[tex]Height = 230.38\ m[/tex]

[tex]Base = 146.5\ m[/tex]

Required

Determine the slope

Slope is calculated as thus:

[tex]Slope = Rise/Run[/tex]

In this case:

[tex]Rise = Height = 230.38 m[/tex]

[tex]Run = Base = 146.5 m[/tex]

So, we have:

[tex]Slope = 230.38 / 146.5[/tex]

[tex]Slope = 1.57[/tex] (approximated)

Answer:

x=5 over 2 (it's a fraction)

Step-by-step explanation:

STEP 1 distribute : 4-1 (2x+4)=5

4-2x-4=5

STEP 2 subtract: 4-2x-4=5

-2x=5

STEP 3 divide both sides of the equation by the same term:

-2x=5

-2x 5

STEP 4 simplify:

cancel the terms that are both the numerator and denominator

Answer: 2 miles per hour

Step-by-step explanation: This is a fraction equal to

6 miles ÷ 3 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 3

6 miles ÷ 3

3 hours ÷ 3

=  

2 miles

1 hour

=  

2 miles

Answer:

x = 98

y = 126

Step-by-step explanation:

If you match triangle abc to triangle cde, you will match where x and y is.

168 ÷ 12 = 14

Now you multiply 14 by the other side lengths

9 • 14 = 126

7 • 14 = 98

It is similar to a dilation.

Answer:

16 teaspoons

Step-by-step explanation:

4x4= 16 teaspoons

The amounts of oil and vinegar combined to make the salad dressing are

in a constant definite proportion.

The quantity of oil required to make 28 teaspoons of dressing is 16

teaspoons.

Reasons:

According to the question, 4 parts of oil are added to every 3 parts of

vinegar.

Therefore;

The ratio or proportion of oil to vinegar in the salad dressing is 4 : 3

4 : 3 = [tex]\dfrac{4}{3}[/tex]

The proportion of oil to vinegar is therefore;

[tex]\mathrm{Amount \ of \ oil = \mathbf{\dfrac{4}{3} \times \ Amount \ of \ vinegar}}[/tex]

Which gives;

[tex]\mathrm{Amount \ of \ vinegar= \dfrac{3}{4} \times \ Amount \ of \ oil}[/tex]

Let x represent the amount of oil required to make 28 teaspoons of dressing,

we have;

[tex]\mathrm{Amount \ of \ vinegar \ required = \dfrac{3}{4} \times x}[/tex]

Which gives;

[tex]\mathrm{x + \dfrac{3}{4} \times x = 28}[/tex]

[tex]\mathrm{x + \dfrac{3}{4} \times x = \dfrac{7}{4} \times x = 28}[/tex]

Therefore;

[tex]x = \dfrac{4}{7} \times 28 = \dfrac{4}{7} \times 7 \times 4 = 4 \times 4 = 16[/tex]

The amount of oil required to make 28 teaspoons of dressing, x = 16 teaspoons.
