Answer:

the answer is C Non durable

Step-by-step explanation:

Answer:

  about 21.9%

Step-by-step explanation:

The effective annual multiplier is ...

  (1 +r/n)^n = (1 +0.20/12)^12 ≈ 1.21939

The rate equivalent is 1 less than this:

  1.21939 -1 = 0.21939 = 21.939%

Answer:

n = -1.5

Step-by-step explanation:

[tex]\frac{1}{(\sqrt2)^{3} } } = 0.353553[/tex]

log ( [tex]2^{n}[/tex] ) = log (.353553)

n = [tex]\frac{log (0.353553) }{log (2)} = -1.5[/tex]

Answer:

C. 83.5%

Step-by-step explanation:

-1 < z < 2.5

0.9938-0.1587 = 0.8351

83.5%

Answer:

Option C.

Step-by-step explanation:

By the property of unique triangles (ASA), one side is included between the two angles.

By this property, if included side of the triangle ABC is AB then this side will be included between the two angles A and B.

Therefore, [tex]\bar{AB}[/tex] is included between ∠A and ∠B.

Option C. will be the answer.

Answer:

This is a pretty broad question but im guessing you could use math to calculate how many people would get infected each day. You could start with

Ex.

Okay if we have one infected person how many people could they possibly pass the illness onto the next day. Well if they have x number of classes and see y number of people in those classes whats the PROBABILIITY one of those people gets the virus. Than you could calculate how many people will get infected the NEXT day.

Answer:

the answer is c. rectangle

Answer:

y = x² + 7x + 4

Step-by-step explanation:

First option

System of equations:

y = x² + x – 4

y = x – 5

Replacing:

x - 5 = x² + x – 4

0 = x² + x – 4 - x + 5

0 = x² + 1

Discriminant:

b²-4*a*c

0²-4*1*1

-4 < 0   then the equation has no real roots

Second option

System of equations:

y = x² + 2x – 1

y = x – 5

Replacing:

x - 5 = x² + 2x – 1

0 = x² + 2x - 1  - x + 5

0 = x² + x + 4

Discriminant:

b²-4*a*c

1²-4*1*4

-15 < 0   then the equation has no real roots

Third option

System of equations:

y = x² + 6x + 9

y = x – 5

Replacing:

x - 5 = x² + 6x + 9

0 = x² + 6x + 9  - x + 5

0 = x² + 5x + 4

Discriminant:

b²-4*a*c

5²-4*1*4

9 > 0 then the equation has two different real roots

Fourth option

System of equations:

y = x² + 7x + 4

y = x – 5

Replacing:

x - 5 = x² + 7x + 4

0 = x² + 7x + 4 - x + 5

0 = x² + 6x + 9

Discriminant:

b²-4*a*c

6²-4*1*9

0  then the equation has one real root

Answer: y = x² + 7x + 4

Answer:

5

Step-by-step explanation:

Answer:

The number is 5

Step-by-step explanation:

3x -2 = 13

Add 2 to each side

3x-2+2 = 13+2

3x = 15

Divide each side by 3

3x/3 = 15/3

x = 5

Answer:

i think it's like this

Step-by-step explanation:

w+7x+3x=180

w+10x=180

54+10x=180

10x=180-54

10x=126

x=126-10

x=116

Answer=116

I hope it's right :)

Answer:

The measure of angle 2 is 38 degrees

Step-by-step explanation:

38 degrees and angle 6 are vertical angles and are equivalent. Angle 6 and 2 are alternate interior angles meaning that they are also equivalent. So the angle of measure 2 must be 38 degrees.

Answer: 38 degrees

Step-by-step explanation: angle 8 is an exterior angle to angle 4. Angle 4 is vertical to angle 2 so the answer would be 38 degrees.

Answer:

715 in^3; Option D

Step-by-step explanation:

We know that the basic formula for most 3 - dimensional figures is to multiply the base by height. Here the base consists of dimensions 13 by 11, with height 5 inches so that the volume of this rectangular prism can be calculated through the following procedure;

[tex]Base - 13 in * 11 in = 143 in * in = 143 square inches,\\Height - 5 inches,\\Volume of Rectangular Prism - Base * Height = 143 square inches * 5 inches = 715 cubic inches / 715 in^3\\\\Solution; 715 in^3[/tex]

Volume of Prism ⇒ 715 in^3; Option D

Answer:

it's D

Answer:

Step-by-step explanation:

Amount invested by Nelson = $1,000,000

Interest rate per month = 4.8%

Simple Interest = Principal * Rate * Time/100

simple Interest = $1,000,000 * 4.8 *(1/12)/100

simple Interest = $1,000,000 * 4.8/1200

simple interest = $4,000/ month

Simple interest for one year = $4,000*12 = $48,000

In order to determine the number of years it will take Nelson to earn back his initial investment, we will divide its initial investment by the interest earned on the investment yearly as shown;

amount of years =  $1,000,000/ $48,000

Amount of years = 20.8years ≈ 21years

10.7 years

Answer: the amount of the annuity is $501000

Step-by-step explanation:

We would apply the future value which is expressed as

FV = C × [{(1 + r)^n - 1}/r]

Where

C represents the yearly payments.

FV represents the amount of money

in your account at the end of 25 years.

r represents the annual rate.

n represents number of years or period.

From the information given,

r = 4% = 4/100 = 0.04

C = $12000

n = 75 - 50 = 25

Therefore,

FV = 12000 × [{(1 + 0.04)^25 - 1}/0.04]

FV = 12000 × [{2.67 - 1}/0.04]

FV = 12000 × 41.75

FV = $501000

Step-by-step explanation:

Keep in mind that distance is positive, not negative.  Eliminate the negative results.

- 3.9 - (-15.1)] = 11.2 is correct.  -(-15.1) - 3.9 is approximately 15 - 4, or 11, which agrees with the 11.2 correct result.

Answer:

1) Yes, table shows a probability distribution

2) Mean = 1.5

3) Standard Deviation = 1.1

Step-by-step explanation:

PART 1:

For the table to show a probability distribution, the sum of all probabilities should be equal to 1

Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025

Sum of probabilities = 1

Hence, the table shows the probability distribution.

PART 2:

The formula for mean is given by:

Mean = Sum of terms/ Total no. of terms

Mean = (0+1+2+3) / 4

Mean = 1.5

PART 3:

The formula for standard deviation is given by:

[tex]\sigma=\sqrt{\frac{\sum(x_i-\mu)^2}{N}}[/tex]
