Rico bicycles at an average speed of 15.5 miles per hour. What distance will Rico bicycle in 180 minutes?
Tpy6a [65]

Answer:

46.5 miles

Step-by-step explanation:

Average speed × Time in hours = Distance

Average speed = 15.5 Miles per hour

Time = 180 minutes

We convert to hours

60 minutes = 1 hour

180 minutes = x

Cross Multiply

60x = 180

x = 180/60

x = 3 hours

Distance = 15.5 miles per hour × 3 hours

Distance = 46.5 miles

The distance Rico will ride his bicycle is 46.5 miles

X2 + 12x =<br> – 20<br> what are the roots of the following quadratic equation
Dmitry_Shevchenko [17]

Answer:

x = -2

x = -10

Step-by-step explanation:

<u>Step 1 :</u><u> Rearrange</u>

x² + 12x + 20 = 0

<u>Step 2:</u><u> Factorise</u>

(x + 2)(x + 10)

<u>Step 3:</u><u> Find the roots / values of x</u>

Make each bracket equal zero.

(x + 2) = x = -2

(x + 10) = x = -10

Hope this helps!

A ________ indicates how far an individual raw score falls from the mean of a distribution; the ________ indicates how the score
I am Lyosha [343]

Answer:

A <u>z-score</u> indicates how far an individual raw score falls from the mean of a distribution; the <u>standard deviation</u> indicates how the scores in general scatter around the mean.

Step-by-step explanation:

We have been given an incomplete statement. We are supposed to complete the given statement.

We know that z-score of a data set indicates that a sample score or raw score is how many standard deviation away from the mean. Z-score indicates the distance of a raw score is above or below mean in units.

Therefore, the correct word for 1st blank would be "z-score".

We also know that standard deviation represents the variation of a data set. It tells that data points of a data set are how much close or away from mean of the data set.

Therefore, the correct word for 2nd blank would be "standard deviation".
