7 times 10 times 4 times 1 plus (2 times 1/10) plus (5 times 1/100)

Answers

Answer 1

Answer: 7*10*4*1+(2*1/10)+(5*1/100)=70*4*1+(2*1/10)+(5*1/100)=280*1+(2*1/10)+(5*1/100)=280+(2*1/10)+(5*1/100)=280+(2/10)+(5*1/100)=280+(1/5)+(5*1/100)=1401/5+(5*1/100)=1401/5+(5/100)=1401/5+(1/20)=1121/4=280 and 1/4

Answer 2

Answer: $7*10*4*4+2*1 (1)/(10) + 5* (1)/(10)$
= $(1121)/(4) Decimal: 280.25$

Say that you put the set of tiles shown below into a bag and conduct a series of trials in which you draw one tile randomly from the bag, record the color, and replace it. The table below shows the number of times in each set of trials that you drew a blue tile. Round tiles: 5 purple, 6 orange, 2 yellow, 4 red, 1 white, 10 blue, 5 black, 3 green. Trial 1 2 3 4 5 # of Draws 54 36 80 22 75 # of Blues 18 11 20 4 32 Between the theoretical probability that you will draw a blue tile and the experimental probability that you will draw a blue tile, which is greater, and how much greater is it? Express all probabilities as percentages to two decimal places, and express differences by number of percentage points (for example, 12% is 2 percentage points greater than 10%). a. The theoretical probability is 2.78 percentage points greater than the experimental probability. b. The theoretical probability is 1.49 percentage points greater than the experimental probability. c. The experimental probability is 4.06 percentage points greater than the theoretical probability. d. The experimental probability is 2.17 percentage points greater than the theoretical probability.

What is the equation of the line that passes through (0,3) and (7,0)

Answers

Answer:

y = (-3/7)x + 3

Step-by-step explanation:

As we go from (0,3) to (7,0), x increases by 7 from and y decreases by 3 to 0.

Thus, the slope of this line is m = rise / run = -3/7.

Subst. the appropriate values from this info into the slope-intercept form of the equation of a straight line:

y = (-3/7)x + 3 Note that the y-intercept is given: (0,3).

Solve for x.

16 = -2x - 1

x = -8
x = -7
x = 7
x = 8

Answers

Answer:

x = - 8.

Step-by-step explanation:

Given : 16 = -2x - 1

To find : Solve for x.

Solution : We have given

16 = -2x - 1

On adding both sides by 1

16 + 1 = -2x .

17 = - 2x

On dividing both sides by -2.

x = - 8. 5

If we rounded it it would be - 8 .

Therefore, x = - 8.

I tend to flip so x is on the left, so:

-2x - 1 = 16

-2x = 17

x = -17/2, which is -8.5

Rounding up, your answer would be x = -8 !
