5.A store manager receives a delivery of 1,200light bulbs. The store manager tests all the
lightbulbs and finds that 180 of them are defective.
Based on these results, what can the store
manager predict about the next delivery of 1,800
light bulbs?
Answers
The store manager can predict that there may be approximately 270 defective light bulbs in the next delivery of 1,800 light bulbs.
Based on the given information, we know that 180 out of 1200 light bulbs in the first delivery were defective. We can use this information to estimate the number of defective light bulbs we might expect in the next delivery of 1,800 light bulbs.
To do this, we can use the proportion of defective light bulbs in the first delivery and apply it to the next delivery. The proportion of defective light bulbs in the first delivery is:
180/1200 = 0.15
So, we can expect that approximately 0.15 of the light bulbs in the next delivery will be defective. To find out the actual number of defective bulbs, we can multiply this proportion by the total number of bulbs in the next delivery:
0.15 x 1800 = 270
Therefore, the store manager can predict that there may be approximately 270 defective light bulbs in the next delivery of 1,800 light bulbs. However, this is only an estimate and the actual number of defective bulbs could be higher or lower than this prediction.

have to remember that 'smaller standard deviation' means 'less spread-out'.
First, let's find the mean (average). It's not supposed to change:
1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = 80 and 1/7 .
Now, just pick 7 scores that total 561 and are all bunched up.
The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.
Let's say 77, 78, 79, 80, 81, 82, and 84 .

Answer with explanation:
First Draw ΔG H J, and name the vertices of triangle in same order from G,to H to J.
→→The included angle of sides JG and G H is angle G.
→→Angle H is the opposite angle to side G J.
→→ The side opposite to ∠J is side G H.
If you will interchange the vertices of triangle and write it in any order you will get the same result.There are 6 ways ,
ΔG H J, ΔH G J, ΔH JG, ΔG J H ,ΔJ HG, ΔJ G H.

Answer:
f(17) = 48
Step-by-step explanation:
Since f(x) = 3x-3, to find the value of x when f(x) = 48 can be found by substituting 48 for f(x).
48 = 3x - 3
51 = 3x
17 = x
When x is 17, f(x) is 48.
Answer: x=51/3
Step-by-step explanation:
Make f(x)= 48
48=3x-3
Add 3 on each side
51=3x
Divide by 3
51/3
X=51/3
