Answer:
(0,3)
Step-by-step explanation:
Step 1: 7x-2y=-6 Step 2: 7x-2y=-6 solve by elimination of the y value
2(8x+y=3)2 +(16x+2y=6)
Step 3: 23x=0, which means <u>x=0</u>
Step 4: subtitute 0 into the equation 8x+y=3
you get 8(0)+y=3, which comes to 0+y=3
you get <u>y=3</u>
therefore the solution to this system is (0,3)
Using polynomial concepts, it is found that the sorting of the polynomial expressions from least to greatest based on their degree is given by: I, III, II, IV.
<h3>What is the degree of a polynomial?</h3>
The degree of a polynomial is given by it's largest exponent.
In this problem, the <em>polynomials </em>are given by:
- IV:

Hence, the respective degrees are: 1, 3, 2, 4, and the ordering from least to greatest is: I, III, II, IV.

Answer:
Reflection of point 0(x, y) about y-axis = (-x, y)
Step-by-step explanation:
Following are the rules for a counter clockwise rotation of 90 degrees about the origin for a point O(x,y):
1. Invert the sign of the value of x.
2. The value of y-coordinate remains the same.
For example, a point M(h,k) after reflection gives a point M'(-h,k) using the rules given above. The points on the x-y plane are shown in the image attached.
Answer:
The probability that 34 randomly selected laptops would have a mean replacement time of 3.2 years or less is 0.0018.
Step-by-step explanation:
Test statistic (z) = (sample mean - population mean) ÷ (population sd/√n)
sample mean = 3.2 years
population mean = 3.4 years
population sd = 0.4 year
n = 34
z = (3.2 - 3.4) ÷ (0.4/√34) = -0.2 ÷ 0.0686 = -2.92
The cumulative area of the test statistic is subtracted from 1 to obtain the probability that 34 randomly selected laptops would have a mean replacement time of 3.2 years or less. The cumulative area is 0.9982. Therefore, the probability is (1 - 0.9982 = 0.0018)
