Answer:
y = 120
x = 10.6
Step-by-step explanation:
Given polygons are parallelograms.
In parallelograms, consecutive angles are supplementary which means their sum is equal to 180.
Since two parallelograms are similar:
60 + y = 180 subtract 60 from both sides
y = 120
To find the value of x:
side lengths are proportional because these are similar polygons
cross multiply fractions
18x + 72 = 264 subtract 72 from both sides
18x = 192 divide both sides by 18
x = 10.6 approximately
Answer:
<h3>Option c)Step-by-step explanation:
The alternate hypothesis use the sumbol for the population value
Let p be the proportion , Mean be and stadard deviation be
The null hypothesis states that population value is equal to the value mentioned in the given claim.
(by given).
The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )
∴
The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.
<h3>∴ option c)
