Use a factor tree. 2 * 64 multiply together, so use the tree to organize. Circle prime numbers/perfect square roots. Afterwards, put them together under the radical. A pair becomes one, and they exit the radical.

Find the vertex of this parabola:<br> y = -x2 + 6x – 15
Orlov [11]

y =  - x {}^{2}  + 6x - 15

y {}^{  \gamma  }  =  - 2x + 6

y {}^{ \gamma }  = 0

- 2x + 6 = 0

- 2x =  - 6

2x = 6

x = 3

<h3>Substitute x=3 in y=-x²+6x-15</h3>

y =  - (3) {}^{2}  + 6(3) - 15

y =  - 9 + 18 - 15

y =  - 9 + 3

y =  - 6

Find the value of x in the triangle shown below.<br> X =<br> 44°<br> xo<br> 29°
densk [106]

Answer:

x = 107°

Step-by-step explanation:

The sum of all 3 angles in any triangle needs to equal 180°.

This means that 44° + 29° + x = 180°

180° - 44° - 29° = 107°

Hypothesis testing on samples with fewer than 30 participants can be carried out by using the t-value for the corresponding leve
Eva8 [605]

Answer: true

Step-by-step explanation:

Z-tests are statistical calculations that can be used to compare the population mean to a sample mean The z-score is used to tellsbhow far in standard deviations a data point is from the mean of the data set. z-test compares a sample to a defined population and is typically used for dealing with problems relating to large samples (n > 30). Z-tests can also be used to test a hypothesis. Z-test is most useful when the standard deviation is known.

Like z-tests, t-tests are used to test a hypothesis, but a t-test asks whether a difference between the means of two groups is not likely to have occurred because of random chance. Usually, t-tests are used when dealing with problems with a small sample size (n < 30).

Both tests (z-tests and t-tests) are used in data with normal distribution (a sample data or population data that is evenly distributed around the mean).
