Answer:

\boxed{\bold{\huge{\boxed{x = 10}}}}

Step-by-step explanation:

=> \sf \frac{3}{4} x + \frac{5}{6} = 5x - \frac{125}{3}

Combining like terms

=> \sf \frac{3x}{4} - 5x = -\frac{125}{3} - \frac{5}{6}

Taking LCM to make the denominator same

=> \sf \large{\frac{3x-20x}{4} = \frac{-250-5}{6} }

=> \sf \frac{-17x }{4} = \frac{-255}{6}

=> \sf \frac{17x }{4} = \frac{255}{6}

Cross Multiplying

=> \sf 17x * 6 = 4 * 255

=> \sf 102x = 1020

Dividing both sides by 102

=> x = 10

Javier made 180 cupcakes. Each cupcake is covered with frosting. • 1/3 of the cupcakes have vanilla frosting. • 1/10 of the cupc
lorasvet [3.4K]

Answer:

30 strawberry cupcakes

Step-by-step explanation:

180 cupcakes in total

1/3 of 180 - 60 = vanilla

1/10 of 180- 18 = lemon

2/5 of 180 - 72 = chocolate

rest of 180 - 180-(72+18+60) = strawberry

rest of 180 - 180-150 = 30 = strawberry

Add all of them:

60 vanilla

18 lemon

72 chocolate

30 strawberry

---------------------------

180 cupcakes

Hope this helps!

8.52 The heights of 2-year-old children are normally distributed with a mean of 32 inches and a standard deviation of 1.5 inches
sweet [91]

Answer:

Heights of 29.5 and below could be a problem.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The heights of 2-year-old children are normally distributed with a mean of 32 inches and a standard deviation of 1.5 inches.

This means that \mu = 32, \sigma = 1.5

There may be a problem when a child is in the top or bottom 5% of heights. Determine the heights of 2-year-old children that could be a problem.

Heights at the 5th percentile and below. The 5th percentile is X when Z has a p-value of 0.05, so X when Z = -1.645. Thus

Z = \frac{X - \mu}{\sigma}

-1.645 = \frac{X - 32}{1.5}

X - 32 = -1.645*1.5

X = 29.5

Heights of 29.5 and below could be a problem.
