In the year 1900, the total number of metric tons of copper purchased in the world was 495,000. Each year since 1990,
the total number of metric tons of copper production has increased on average by 3.25%. Which function models the
total number of metric tons produced, y, for x years since 1990?
А
c(2) = 495.000,20.9675
cc() = 495, 000(1.0325)*
B.
C(2) = 495,000...1.0325
D
c(2) = 495,000(0.9675)

Step-by-step explanation:

shirley earned 50 dollars before farah started saving

50-15

60-30

70-45

80-60

90-85

100-100

6 days

In 10 days Farah and Shirley will have the same amount of money

A linear equation is an alzebraic expression which has highest degree of one and contains only one variable.

In the given question farah saved 15$/day and Shirley saved 10$/day

Shirley started 5 days earlier so in 5 days she will save 10 x 5 = 50$

let assume days to be x.

So,

   10x + 50 = 15x

   5x = 50

    x = 10 .

Step-by-step explanation:

Rather than taking it on and overthinking it the way everyone else does, do it the simple way, like this:

15/3 = 5, right? and 5, when multiplied by 4, becomes 20, right? So divide 4 by 3, and then take that number, and muliply it by 4.

Like this: (4 / 3) * 4, and then you know that 5 L of gas requires 1.33e L of oil. So, like 5*4 = 20, so is 1.33e *4, the amount of oil in 20 L. In all, the answer is 5.33e, or [tex]5 \frac{3}{5}[/tex] or whatever your answer might have to be

Given:

Of the 50 flips, the coin landed on heads 30 times.

To find:

The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.

Solution:

We have,

Total number of trials = 50

Total number of heads = 30

The experimental probability of flipping heads is:

[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]

[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]

[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]

[tex]\text{Experimental probability}=0.6[/tex]

A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:

[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]

[tex]\text{Theoretical probability}=0.5[/tex]

Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.

Answer:

a + b = 100

a - b = 6

2a = 106

2a/2 = 106/2

a = 53

53 + b = 100

53 + b - 53 = 100 - 53

b = 47

91

Step-by-step explanation:

Mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

let x be his test score of his last test , then

[tex]\frac{86+70+72+100+96+80+x}{7}[/tex] = 85 ( multiply both sides by 7 )

504 + x = 595 ( subtract 504 from both sides )

x = 91

Answer:

The total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

Step-by-step explanation:

Complete question

Tom started a stamp collection with 32 stamps. Each week he added 8 stamps to his collection.

Rhea started her stamp collection with 102 stamps. Each week she gave away 6 stamps.

Write an equation to represent the number of stamps in Tom’s collection based on the  number of weeks he has been collecting stamps.

Solution

Let "X" be the number of weeks for which Tom collected the stamps

The number of stamps that Tom had at the time of starting the collection [tex]= 32[/tex]

It is given that he collects 8 stamps per week

So the total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]
