Answer:
−2
Step-by-step explanation:
Using the slope-intercept form, the slope is −2 .
O False
Answer:
True
Step-by-step explanation:
The skip interval in systematic random sampling is computed by dividing the number of potential sampling units on the list by the desired sample size .
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval (the sampling interval).
Sampling interval is calculated by dividing the population size by the desired sample size
Answer:
the answer is 25 degrees
Answer:
alpha = 25°
Step-by-step explanation:
The picture indicates a rectangle.
Alpha is in a straight corner of 90 °, so...
65 + alpha = 90
subtract 65 left and right of the = sign.
65 - 65 + alpha = 90 - 65
0 + alpha = 90 - 65
alpha = 25°
The dilated polygon and polygon are created. And the scale factor of the polygon STUVWXYZ to JKLMNOPQ will be 9.
Dilation is the methodology of expanding the dimensions of an object without impacting its appearance.
The coordinate of the polygon ABCDEFGH is given as,
(3, -3), (4, -4), (5, -3), (8, -6), (10, -4), (9, -3), (8, -4), (5, -1)
a) If the scale factor is 3, then the coordinate of the polygon JKLMNOPQ is given as,
⇒ 3 [(3, -3), (4, -4), (5, -3), (8, -6), (10, -4), (9, -3), (8, -4), (5, -1)]
⇒ (9, -9), (12, -12), (15, -9), (24, -18), (30, -12), (27, -9), (24, -12), (15, -3)
b) If the scale factor is 1/3, then the coordinate of the polygon STUVWXYZ is given as,
⇒ 1/3 x [(3, -3), (4, -4), (5, -3), (8, -6), (10, -4), (9, -3), (8, -4), (5, -1)]
⇒ (1, -1), (4/3, -4/3), (5/3, -1), (8/3, -2), (10/3, -4/3), (3, -1), (8/3, -4/3), (5/3, -1/3)
c) The polygon JKLMNOPQ and STUVWXYZ are similar. Then the scale factor is given as,
Scale factor = 9/1
Scale factor = 9
The diagram is given below.

Answer:
Ordinal
Step-by-step explanation:
Level of measurement used in statistics summarizes what statistical analysis that is possible. There exist three types of level of measurement. The nominal, ordinal and Interval/Ratio level of measurement. Here, our primary focus will be the Ordinal level of measurement.
Ordinal level of measurement indicates the position in a sequence. In the military sector, the officer's rank is said to be Ordinal. This implies that the ordinal level of measurement categorizes variables according to hierarchy or ranks with a meaningful order. Still, the intervals and differences between the variables may not be equal.
The level of measurement for an officer's rank in the military, is classified as ordinal because there's a distinct order but not a measurable difference between ranks.
The level of measurement for an officer's rank in the military is ordinal. This is because it contains a set order or ranking, without a measurable difference between each rank. For instance, a Colonel is above a Captain, but there's no defined 'numeric difference' you can attribute between the two ranks since it's not a sequence of numbers. This is distinct from levels like interval or ratio, where a specific measurable difference could be discerned between the ranks.

Answer: The sum of a rational number and an irrational number is irrational.
Step-by-step explanation:An irrational number in decimal form goes forever without repeating.
y = -4x + 5
y = 1/4x + 5
y = 4x - 5
Answer:
y=-4x + 3
