There are 25 gold cards and 25 silver cards in a deck. The gold cards are number 1,3,5,.....49 and the silver cards are numbered 2,4,6,.....50. The cards are thoroughly shuffled and one card is randomly selected.A.) Find the probability of selecting a gold card or a card with a multiple of 10 on it.
B.) Find the probability of selecting a silver card or a card with a multiple of 7 on it.

Answers

A. There are 25 gold cards, and 5 silver cards with a multiple of 10, so the probability is (25+5)/50=0.6.

B. There are 25 silver cards and 4 gold cards with a multiple of 7 (7, 21, 35, and 49), so the probability is (25+4)/50=0.58.

Solutions

There are 25 gold cards and 25 silver cards in a deck. The gold cards are number 1,3,5,.....49 and the silver cards are numbered 2,4,6,.....50.

A. The probability would be (25+5)/50=0.6.

B.we know that there are 25 silver cards and 4 gold cards with a multiple of 7, so the probability would be (25+4)/50=0.58.

B.10 square root over 8

C.5 square root over 4

D.4 square root over 5

Answers

The number √80 in simplified radical form is 4√5. Therefore, the correct answer is option D.

The given number is √80.

Radical form is the expression that involves radical signs such as square root, cube root, etc instead of using exponents to describe the same entity.

Here, factors of number 80 are 2×2×2×2×5

= √16×5

= 4√5

Therefore, the correct answer is option D.

Cheyanne plans to put $150 into a savings account. she can place her money into an account represented by f(x)=5x+150, or into another account represented by g(x)=150(1.03)^x. which account has the highest value in 3 years? which account has the highest value in 10 years?1. f(x) has the highest value in 3 years; g(x) has the highest value in 10 years

2. g(x) has the highest value in 3 years; f(x) has the highest value in 10 years

3. f(x) has the highest value in 3 years; f(x) has the highest value in 10 years

4.g(x) has the highest value in 3 years; g(x) has the highest value in 10 years

Answers

Answer: 1. f(x) has the highest value in 3 years; g(x) has the highest value in 10 years

Step-by-step explanation:

Given:- Principal amount= $150

First account represented by the function= $f(x)=5x+150$ →Linear function

Second account represented by the function= $g(x)=150(1.03)^x$ →Exponential function

where x is the time period in years.

When x=3 years

$f(3)=5(3)+150=15+150=\$165$

$g(3)=150(1.03)^3=\$163.90$

here, f(x) has the highest value .

When x=10 years

$f(10)=5(10)+150=50+150=\$200$

$g(10)=150(1.03)^(10)=\$201.58$

g(x) has the highest value.

Therefore, f(x) has the highest value in 3 years; g(x) has the highest value in 10 years

For the first 3 years of a horse's life, the weight, w (in kilograms), of the horse approximately fits the formula w(t)=30+170t, where t is the age of the horse in years. Which of the following is the most accurate interpretation of the slope of the line represented by this formula? A. The slope is 170. This means that the horse gains an average of 170 kilograms per year for the first 3 years of its life.
B. The slope is 30. This means that the horse gains a total of 30 kilograms in the first 3 years of its life.
C. The slope is 30. This means the horse gains on average 30 kilograms per use for the first 3years of its life.
D. The slope is 170. This means that the horse gains a total of 170 kilograms in the first 3 years of its life.

Answers

Answer:

Option A. The slope is 170. This means that the horse gains an average of 170 kilograms per year for the first 3 years of its life

Step-by-step explanation:

Let

t ----> the number of years

w ---> is the weight in kilograms of the horse

we know that

The equation of a line in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

$w(t)=30+170t$

where

The slope or unit rate is equal to

$m=170\ (kg)/(year)$ ---> (for the first 3 years of a horse's life)

The y-intercept is equal to

$b=30\ kg$ ---> value of w when the value of t is equal to zero

therefore

The slope is 170. This means that the horse gains an average of 170 kilograms per year for the first 3 years of its life
