Mathematics
1 answer:
eduard3 years ago
7 0

Answer:

p=\frac{8}{7}

Step-by-step explanation:

\frac{2}{4} = \frac{4}{p} - 3

\frac{1}{2} = \frac{4}{p} - 3 (simplify)

\frac{1}{2}+3 = \frac{4}{p} - 3+3

\frac{1}{2}+3 = \frac{4}{p} (Add 3 to both sides)

\frac{7}{2}= \frac{4}{p} (simplify)

\frac{7}{2}p= \frac{4}{p}*p

\frac{7p}{2}=4 (Multiply both sides by p)

\frac{7p}{2}*2=4*2

7p=8 (Multiply both sides by 2)

\frac{7p}{7}=\frac{8}{7}

p=\frac{8}{7} (Divide both sides by 7)

A restaurant used 8 1/4 pounds of carrots to make 6 carrot cakes. Frank wants to use the same recipe. How many pounds of carrots
snow_tiger [21]

Answer:

To make one carrot cake 1 pound(approximately) carrot needed.

Step-by-step explanation:

Given:

8 1/4=33/4 pounds of carrots used to make 6 carrot cakes.

So, to get one carrot cake:

6 carrot cakes need = \frac{33}{4}

1 carrot cake need =  \frac{33}{4} ÷ 6

                               = \frac{33}{24}

                               = 1.375\ pound

Therefore, to make one carrot cake 1 pound(approximately) carrot needed.

Translate this sentence into an equation.
Dennis_Churaev [7]

Answer: ALEKS LINEAR EQUATIONS AND INEQUALITIES

h-23=63  

Step-by-step explanation:

We must translate this sentence into an equation.

Helena's age decreased by 23 is 63.

The words decreased by tell us to subtract.

In particular, Helena's age decreased by 23 means −h23.

The word is means equals.

So we get the following.

h-23=63

PLEASE HELP!!!! WILL GIVE BARAINLYIST!!!!

Experimental probability = 1/5

Theoretical probability = 1/4

note: 1/5 = 0.2 and 1/4 = 0.25

=============================================

How I got those values:

We have 12 hearts out of 60 cards total in our simulation or experiment. So 12/60 = (12*1)/(12*5) = 1/5 is the experimental probability. In the simulation, 1 in 5 cards were a heart.

Theoretically it should be 1 in 4, or 1/4, since we have 13 hearts out of 52 total leading to 13/52 = (13*1)/(13*4) = 1/4. This makes sense because there are four suits and each suit is equally likely.

The experimental probability and theoretical probability values are not likely to line up perfectly. However they should be fairly close assuming that you're working with a fair standard deck. The more simulations you perform, the closer the experimental probability is likely to approach the theoretical one.

For example, let's say you flip a coin 20 times and get 8 heads. We see that 8/20 = 0.40 is close to 0.50 which is the theoretical probability of getting heads. If you flip that same coin 100 times and get 46 heads, then 46/100 = 0.46 is the experimental probability which is close to 0.50, and that probability is likely to get closer if you flipped it say 1000 times or 10000 times.

In short, the experimental probability is what you observe when you do the experiment (or simulation). So it's actually pulling the cards out and writing down your results. Contrast with a theoretical probability is where you guess beforehand what the result might be based on assumptions. One such assumption being each card is equally likely.
