What is the distance between (-3,5) (7,5)
Firlakuza [10]

Answer:

10 units

Step-by-step explanation:

use distance formula:  d = square root of the difference of the y-values minus the difference of the x-values

d = \sqrt{(5-5)^2+(7--3)^2}

d = \sqrt{(0)^2+(10)^2}

d = \sqrt{100}

d = 10 units

ΔPQR has angle measurements of 80°, 50°, and 50°. What kind of triangle is ΔPQR?
trasher [3.6K]

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle-  a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.

Find the surface area of a solid cylinder with radius 2m and length 6m ( famula)π=3.14​
Softa [21]

Answer:

100.544m

Step-by-step explanation:

Surface area of a cylinder = 2pie x rh + 2pie x r² where pie = 3.142

Therefore, (2x3.142x2x6) + (2x3.142x2²) =100.544m

Due to normality, the formula for computing z is the same for a single data value, as it is
katrin2010 [14]

Using the <u>Central Limit Theorem</u>, the statement is false, as for the averages of  the data values for a sample group, the standard error is s = \frac{\sigma}{\sqrt{n}}, hence, the formula is:

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

While for a single value, it is:

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

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

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

  • It 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, which is the percentile of X.
  • By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation s = \frac{\sigma}{\sqrt{n}}.

Hence, the formulas are different, and for an average of the data values for a sample group it is:

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