\huge \boxed{\mathfrak{Question} \downarrow}

  • Hong needs to memorize words on a vocabulary list for Russian class. He has 14 words to memorize, and he is one-half done. How many words has hong memorized so far?

\huge \boxed{\mathfrak{Answer} \downarrow}

  • Number of words Hong needs to memorize = \sf \: 14 \: words
  • Words he has finished = \sf \:  \frac{1}{2} \: of \: the \: words \: given  \\
  • Words left for Hong to memorize = ?

\huge \boxed{\mathfrak{Steps} \downarrow}

\large \sf \: 14 \times  \frac{1}{2}  \\\large \sf =  \bcancel14 \times  \frac{1}{ \bcancel2}   \\ \large \sf = 7 \times 1 \\  = \large \boxed{ \bf7 \: words}

=> Hong has <u>7 more words</u> to complete if he has completed about one-half of the total number of words given.

The weight of laboratory grasshoppers follows a Normal distribution, with a mean of 90 grams and a standard deviation of 2 grams
JulsSmile [24]

Answer:

95.44% of the grasshoppers weigh between 86 grams and 94 grams.

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.

Mean of 90 grams and a standard deviation of 2 grams.

This means that \mu = 90, \sigma = 2

What percentage of the grasshoppers weigh between 86 grams and 94 grams?

The proportion is the p-value of Z when X = 94 subtracted by the p-value of Z when X = 86. So

X = 94

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

Z = \frac{94 - 90}{2}

Z = 2

Z = 2 has a p-value of 0.9772.

X = 86

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

Z = \frac{86 - 90}{2}

Z = -2

Z = -2 has a p-value of 0.0228.

0.9772 - 0.0228 = 0.9544

0.9544*100% = 95.44%

95.44% of the grasshoppers weigh between 86 grams and 94 grams.

 An athlete runs an equal distance 2 days a week. The other 5 days of the​ week, he runs a total of 11 miles. Write an equation
katovenus [111]
Ok since the athlete an equal distance of 2 days a week and he runs a total of 11 miles in 5 days you will need to think back so before he had 11 miles done next weak he had a total of 19 miles so you will start at 11 then count up to 19.

Use a number line to show how many days it took for the athlete to get 19 miles.

Then once you do the number line count the lumps and that’s how many days it took for the athlete to get 19 miles.

Hope this helped.
