Answer:
2520
Step-by-step explanation:
There are 405 deer per 45 tags.
The ranger tagged 280 deer.
No. of deer = 280 × 405/25
No. of deer = 280 × 9
No. of deer = 2520 deer
There are 2520 deer in the forest
Answer: C
Step-by-step explanation:
To get all the constant terms on one side and variable terms on another, all we have to do is to add or subtract them on both sides.
3x+2x=10+5
Now that the like terms are on one side, we can combine them.
5x=15
To get x alone, we divide both sides by 5.
x=3
Now, we notice that x=3 is not an answer choice, but the next option that is equivalent to x=3 is C.
For C, if you divide both sides by -5, you still get x=3.
-15=-5x
x=3
The standardized z-score is calculated as (actual score - mean)/(standard deviation).
A. Idonna's z-score would be (670 - 514)/118 = 1.322
Jonathan's z-score would be (26 - 20.9)/5.3 = 0.962
B. This implies that Idonna's score is higher, since it is more standard deviations above the mean.
I believe 2x - 9 is correct. Correct me if I am wrong
Answer:
A
Step-by-step explanation:
We know a number is an expression when it is:
1) NOT greater/ less than something else
2) NOT equal/ not equal to something else
The only answer choice that satisfies the above is A.
