This is basically saying how much of the pizza did Tashia and Jay both ate, thus combining their portions together.
1/3 + 3/8 = fraction of pizza eaten
To add fractions, you must have a common denominator. Which is 24 in this case because 3*8 = 24.
So you multiply 1/3 with 8 and multiply 3/8 with 3.
1/3*8= 8/24
3/8*3= 9/24
Now you add the fractions.
8/24+9/24= 17/24. You add the numerator, the denominator stays the same.
17/24 of the pizza was eaten.
Given (-4,9) (-8,9),(-9,7,(-9,4)
...
To Find : plot the point and draw quadrilateral
Solution:
(-4,9)
go 4 left of origin and then go 9 up
(-8,9)
go 8 left of origin and then go 8 up
(-9,7)
go 9 left of origin and then go 7 up
(-9,4)
go 9 left of origin and then go join (-4,9) with (-8,9) and (-9,4) 4 up
join (-9,7) with (-8,9) and (-9,4)
Quadrilateral is constructed
84 cm because you HAVE to add them together.
Answer:
<u>The probability that a randomly selected boy in school can run the mile in less than 348 seconds is 1.1%.</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
μ of the time a group of boys run the mile in its secondary- school fitness test = 440 seconds
σ of the time a group of boys run the mile in its secondary- school fitness test = 40 seconds
2. Find the probability that a randomly selected boy in school can run the mile in less than 348 seconds.
Let's find out the z-score, this way:
z-score = (348 - 440)/40
z-score = -92/40 = -2.3
Now let's find out the probability of z-score = -2.3, using the table:
p (-2.3) = 0.0107
p (-2.3) = 0.0107 * 100
p (-2.3) = 1.1% (rounding to the next tenth)
<u>The probability that a randomly selected boy in school can run the mile in less than 348 seconds is 1.1%.</u>
