Answer:
y=-11/2-1/2x
Step-by-step explanation:
2x + 4y = -22
4y = -22 - 2x
y=-11/2-1/2x
Answer:
6th week.
Step-by-step explanation:
Each week he is selling 1/2 of the week before so
In the 3rd week he sells 400
- in the 4th week it will be 200
- in 5th week 100
- in 6th seek 50.
Answer:
.64 < 65 % < 2/3 < 7/10
Step-by-step explanation:
To order all the numbers from least to greatest, but all the numbers in the same form (fraction, decimal, or percent). I will put them all in decimal form so that I can compare them.
0.64, .64
2/3 , =.666666repeating
65% = 65/100 = .65
7/10 = .7
.64< .65<.6666repeating<.7
but we need to put them in their original form
.64 < 65 % < 2/3 < 7/10
Answer:
The volume and the curved surface area of the solid formed is and respectively.
Step-by-step explanation:
Given that,
A right triangle with sides 6 cm, 8 cm and 10 cm is revolved about the side 8 cm.
As the triangle is revolved at 8 cm it forms a cone of height 8 cm and radius 6cm.
Height, h = 8 cm
Radius, r = 6 cm
The volume of the solid formed is given by :
The curved surface of the solid formed is :
l is slant height
Hence, the volume and the curved surface area of the solid formed is and respectively.
Answer:
The probability is 0.5438
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:
a. If 1 candy is randomly selected, find the probability that it weighs more than 0.8542g.
This is 1 subtracted by the pvalue of Z when X = 0.8542. So
has a pvalue of 0.4562
1 - 0.4562 = 0.5438
The probability is 0.5438
