Answer:
Student 2 used the correct steps to construct parallelogram PQRS.
Step-by-step explanation:
Out of all the students, student 2 got all the steps correct.
Fix the compass at Q and draw an arc that intersects side QP.
Without changing the width of the compass, move the compass to R and draw an arc.
Draw a line segment from R that passes through T and intersects the second arc at S.
Answer:
99.7%
Step-by-step explanation:
Using the z score formula
z-score is z = (x-μ)/σ
where:
x = raw score
μ = population mean
σ = population standard deviation.
a) for x = raw score = 35
μ = population mean = 44
σ = population standard deviation =3
z = (35 - 44)/3
z = -9/3
z = -3
b) for x = raw score = 53
μ = population mean = 44
σ = population standard deviation =3
z = (53 - 44)/3
z = 9/3
z = 3
We would use the standard normal distribution table to find their probabilities
P(Z<=-3)=0.0013499
P(Z<=+3)=0.99865
So P(-3<=Z<=3)=0.99865 - 0.0013499 = 0.9973
Converting to percentage = 0.9973 × 100 = 99.73%
Therefore, the percentage of auto batteries of this brand that have a life of 35 to 53 months to one decimal place is 99.7%
Answer:
x=2 and y=3
Step-by-step explanation:
3x+2y=12
3(2) + 2(3)
6 + 6 = 12
12x+8y=48
12(2) + 8(3)
24+24=48
