Answer:
18 stickers.
Step-by-step explanation:
Cindy buys 18 more stickers in the start. This results in 13+18= 31 stickers. She then gets five for her birthday. 31+5=36 so she now has 36 stickers but she then gives eight away which means she has 36-8=28 stickers. She uses ten stickers to decorate so Cindy has 28-10=18 stickers left
Answer:
15.87% probability that the car travels more than 53 miles per gallon.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

Find the probability of the following events: A. The car travels more than 53 miles per gallon. Probability
This is the pvalue of Z when X = 53. So



has a pvalue of 0.8413
1 - 0.8413 = 0.1587
15.87% probability that the car travels more than 53 miles per gallon.
Answer:
see below
Step-by-step explanation:
27) y = kx
18 = k(20)
18 = 20k
k = 0.9
28) y = kx
-9 = k(3)
-9 = 3k
k = -3
y = -3x
29a) y = kx
5 = k(1/3)
5 = 1/3k
k = 15
y = 15x
29b) y = 15x
y = 15(-2)
y = -30
Answer:
We are talking about a cyclic quadrilateral, where the opposite angles are supplementary. Once the consecutive angles of a parallelogram are supplementary (sum = 180º) a rectangle is the only parallelogram that can be inscribed in a circle.
