4x-11=13

4x=13+11

4x=24

x=24/4

x=6

4x=13+11

4x=24

x=24/4

x=6

Wouldn't it be 24? Because the range is the max-minimum=range. So the equation is x-16=8, which is x=24

Hey there!

For this problem and future problems like these, you'll want to memorize the phrase "SOHCAHTOA," which indicates which sides of the triangle are equal to which trigonomic function.

Sine = Opposite/Hypotenuse

Cosine = Adjacent/Hypotenuse

Tangent = Opposite/Adjacent

Based on that, you need to know which sides on the triangle are which. I attached an image for reference. The image I attached references the right angle, however, you'll want to reference angle A on your triangle instead, based on the problem.

Based on that, you should be able to easily divide your numbers and get your answer.

Hope this helped you out! :-)

TRUE. I'm going to be using a picture from Google to help me out. In the graph below the line plots are telling how much Sarah's is as the years past. Each line plot tell the data of how much her car cost in whatever year the plot is in. For example, in 2006 her car cost $10,000. How do we know? We know this because the line plot is point towards 10,000 and downwards to 2006. This is data that the line plots are displaying fro us.So yes, line plots do display individual data.

6 pencils were left

-1,000 divided by 7=142.86

-142x7=994

-1,000-994=6

-1,000 divided by 7=142.86

-142x7=994

-1,000-994=6

QUESTION POSTED AT 17/10/2019 - 09:14 AM

If you have 1000 pencils and you divide by 7 teachers, you would have 142 pencils divided evenly. Then you would take the 142 pencils and multiply by 7 which will give you a total of 994 pencils that went to the teachers in total. So the remaining pencils would be 1000 minus 994 and the total left over will be 6 pencils. I hope this helps.

QUESTION POSTED AT 17/10/2019 - 09:07 AM

The shaded region is the area of the circle minus the area

of the pentagon.

A circle = pi * r^2

A circle = pi * 15^2

A circle = 706.5 cm^2

A regular pentagon = (a * p)/2 where a is the apothem, p is the perimeter.

The apothem id the perpendicular height from the midpoint of a side to the center of the pentagon.

To find the apothem you have to use a trig ratio.

A pent = (8.3 * 12*5)/2

A pent = 249 cm^2

Shaded region: circle - pentagon 706.5 - 249 = 457.5

of the pentagon.

This is the concept of probability and statistics, we are required to calculate the probability of getting a red, blue and black respectively, given that there are 3 red, 8 blue and 7 black beads;

Probability of an event occurring=(Number of ways it can occur)/(Total number of outcomes )

The total number of outcome in our situation is:

3+8+7=18

P(Red)=3/18=1/6

P(Blue)=8/17

P(Black)=7/16

since these occurrence are such that the selection is without replacement, that means they are dependent. The probability of them occurring in that order will be:

P(x)=1/6*8/17*7/16=7/204

The answer is d. dependent; 7/204

p/100≈28/252

p≈2800/252

p≈11.11%
