PLEASE ANSWER! I AM GIVING OUT LOTS OF POINTS! IM DESPERATE! Alyssa claims that dividing by 4/5 is he same thing as multiplying
BigorU [14]
No, she is NOT correct because for example, if 20 is multiplied by 4/5 then it first has to be multiplied by 4 then divided by 5 (even though you can use cross multiplying) EX: 20×4=80/5=16

Solve by completing a square r^2-8r+9
Tanzania [10]

Solving  r^2-8r+9 by completing a square gives (r+4)^2-7

Step-by-step explanation:

We need to solve the equation r^2-8r+9 by completing a square

The completing a square method requires: a^2\pm 2ab +b^2=(a\pm b)^2

Solving:

r^2-8r+9\\=(r)^2-2(r)(?)+(?)^2+9

We need to add and subtract (4)^2=16 to make the equation a complete square

=(r)^2-2(r)(4)+(4)^2-(4)^2+9\\=(r)^2-2(r)(4)+(4)^2-16+9\\=(r)^2-2(r)(4)+(4)^2-7\\=(r+4)^2-7

So, Solving  r^2-8r+9 by completing a square gives (r+4)^2-7

You recently took a statistics exam in a large class. The instructor tells the class that the scores were Normally distributed,
Lunna [17]

Answer:

b. the area to the right of 2

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore 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, which is also the area to the left of Z. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X, which is the area to the right of Z.

In this problem:

X = 96, \mu = 72, \sigma = 12

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

Z = \frac{96 - 72}{12}

Z = 2

Percentage who did better:

P(Z > 2), which is the area to the right of 2.
