Answer:

True.

Step-by-step explanation:

We have been given a statement and we are asked to determine whether our given statement is true or false.

Statement:

A z-score of 1.0 corresponds to a value one standard deviation from the mean.

We know that z-score of a data set represents how many standard deviation a data point is above or below mean.

Since the z-score of a data set is 1.0, so it represents that the data is 1 standard deviation above mean.

Therefore, our given statement is true.

mel-nik [20]

Answer:

Aaron needs <u>2 more rolls</u> to complete the path.

Step-by-step explanation:

Given:

Total rolls Aaron has = 4

Part of path covered by using $\frac{3}{4}$ of a roll = $\frac{1}{8}$

So, in order to find the number of rolls required to cover the complete path is given using the unitary method.

Rolls used for $\frac{1}{8}$ of a path = $\frac{3}{4}$

Therefore, rolls used to cover the whole path is given by dividing the rolls used for one-eighth of the path and the path covered. This gives,

$=\frac{3}{4}\div \frac{1}{8}$

$=\frac{3}{4}\times \frac{8}{1}$

$=\frac{3\times 8}{4\times 1}$

$=\frac{24}{4}$

$=6\ rolls$

Now, rolls required to complete the path is 6. But Aaron has only 4 rolls.

So, he will need 6 - 4 = 2 rolls more to complete the path.

Artist 52 [7]

Answer:

$\boxed{GJ = 76 \ degrees}$

Step-by-step explanation:

According to Angles of intersecting chords theorem:

∠GAJ = $\frac{1}{2} (BD+GJ)$

Where ∠GAJ = 50 , BD = 24 and GJ = ?

50 = $\frac{1}{2} (24+GJ)$

Multiplying both sides by 2

100 = 24 + GJ

GJ = 100-24

GJ = 76 degrees

Free_Kalibri [48]

Answer:

12/13

Step-by-step explanation:

There are 52 cards in the deck

4 are aces

That leaves 52-4 or 48 that are not aces

P(not an aces) = cards that are not aces / total

= 48/52

=12/13

The rabbit population in a forest area grows at the rate of 9% monthly. if there are 270 rabbits in july, find how many rabbits

sukhopar [10]

We will do multiplication, 270x0.9 to find out how many rabbits grow in the area each month. Using that number we will multiply it by 12 because the problem is asking us to find the number of rabbits grown in the are in one year. Our final answer would be 292.
