Find x and y please help

Answer:

x = 40 and y = 70

Step-by-step explanation:

This is an isosceles triangle since the two sides adjacent to the x angle are the same length. The angle opposite the 110 is 70 since these are supplementary angles. Angle y is 70 (isosceles triangle has two sides equal and two angles equal). The sum of the interior angles of a triangle is 180, so x = 180 - 70 - 70 = 40.

Jerome is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability tha

alexira [117]

Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.

Event A - get a green or yellow marble
Event B - get a pink marble

Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
$P(A)= \frac{3+4}{3+4+5+8}= \frac{7}{20} 
\\P(B)= \frac{8}{3+4+5+8}= \frac{8}{20} = \frac{2}{5}$

Probability of combined events is
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$

Which measure of spread is least affected by the long tail in the graph?

trapecia [35]

Answer:

Image result for Which measure of spread is least affected by the long tail in the graph?

IQR

Answer: The IQR is least affected by the long tail on the right of the graph. The IQR is the inter-quartile range. It is the length of the box in the middle of the graph. Having the long tail on the right does not affect the box.
