Answer:
x = 16 treata
Step-by-step explanation:
Let us represent x = Number of treats that Tim can buy
We are told that: Tim does not want to spend more than $62.00 in all.
= Time wants to spend less than or equal to $62.00
Tim is going to an amusement park that cost $30.00 to get into.Treats like cotton candy carmel apples and funnel cakes cost 2.00 dollars each .
Therefore, our inequality equation =
$30.00 + $2.00 × x ≤ $62.00
30 + 2x ≤ 62
Solving for x
30 + 2x ≤ 62
2x ≤ 62 - 30
2x ≤ 32
x ≤ 32/2
x ≤ 16
Hence, Tim can buy no more than(less than or equal to ) 16 treats
Answer:
Option C
Step-by-step explanation:
Given
Mean= μ=60
and
Standard Deviation= σ=5
In order to calculate the percentage of students between 55 and 65, we have to calculate z-score for both
z-score for 55=(55-60)/5
=(-5)/5
=-1
The area to the left of z-score -1 is 0.1587
z-score for 65=(65-60)/5
=5/5
=1
The area to the left of z-score 1 is 0.8413
Area between z-scores of 55 and 65=0.8413-0.1587
=0.6826
Converting into percentage
=0.6826*100
=68.26%
Option C is the correct answer ..
Answer:
1.
Step-by-step explanation:
I am assuming you want to simplify this.
cos^2 x + sin^2 x = 1 and
csc^2 x = 1 + cot^2 x so csc^2x - cot^2 x = 1
So the answer is 1/1 = 1.
3x - 45 = 2x + 5
3x - 2x = 5 + 45
x = 50
4y - 1 + 2x + 5 = 180
4y + 2(50) + 4 = 180
4y = 180 - 4 - 100 = 76
y = 76/4 = 19.
y = 19
