Answer:
The answer is B
Step-by-step explanation:
12y is the amount of money per yard and 40 is the amount already earned. Those two have to be equal to or more than the amount needed.
Answer:
P(a junior or a senior)=1
Step-by-step explanation:
The formula of the probability is given by:
P (AB) = P(A)
Where P(A) is the probability of occurring an event A, n(A) is the number of favorable outcomes and N is the total number of outcomes.
In this case, N is the total number of the students of statistics class.
N=18+10=28
The probability of the union of two mutually exclusive events is given by:
Therefore:
P(a junior or a senior) =P(a junior)+P(a senior)
Because a student is a junior or a senior, not both.
n(a junior)=18
n(a senior)=10
P(a junior)=18/28
P(a senior) = 10/28
P(a junior or a senior) = 18/28 + 10/28
Solving the sum of the fractions:
P(a junior or a senior) = 28/28 = 1
Answer:
Sum of 100 terms of the sequence = 15050
Step-by-step explanation:
Given expression which represents a sequence is,
So the sequence will be,
2, 5, 8, 11, 14..........
So, the given sequence is an arithmetic sequence with,
First term of the sequence 'a' = 2
Common difference 'd' = 5 - 2 = 3
Sum of 'n' terms of an arithmetic sequence is given by,
![S_n=\frac{n}{2}[2a+(n-1)d]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D)
Here, n = number of terms
a = first term
d = common difference
= ![\frac{100}{2}[2(2)+(100-1)(3)]](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7B2%7D%5B2%282%29%2B%28100-1%29%283%29%5D)
= 50[4 + 297]
= 15050
Therefore, sum of 100 terms of the sequence = 15050
Answer:
1: 6
2: 1,2,3
3: 4m-1>5m-4
4: Not enough data
5: n = 11
6: The ceiling is lower than 3m
7: G = 7
8: C = 18
9: p + 18 = 41; p = 23
10: D = 100t
Step-by-step explanation:
Question 1:
5*2+x/2-7
5*2+6/2-7
10+6/2-7
10+3-7
13-7
6
Question 2:
4*2<16
8<16 True
4*1<16
4<16 True
4*3<16
12<16 True
4*4<16
16<16 False
Question 3:
Let's plug in 1 for m
4*1-1____5*1-4
4-1_____5-4
3_____1
3>1
Question 4:
You did not give an equation, so I cannot answer.
Question 5:
2*11 + 5 =27
22 + 5 = 27
27 = 27
So n = 11
Question 6:
x<3
The ceiling is lower than 3m because x<3
Question 7:
5.1g = 35.7
5.1g/5.1=35.7/5.1
g = 7
Check: 5.1 * 7 = 35.7
Question 8:
36 + c = 54
36 + c -36 = 54 - 36
c = 18
Check: 36 + 18 = 54
Question 9:
p + 18 = 41; p = 23 is correct because the number of paperback books plus the number of hardcover books would equal the total number of books sold. Check: 23 + 18 = 41
Question 10:
d=100t is correct because each time t goes up one it goes up 100. Example: if it is at one hour, than it is 100, if it is at 3 hours, than d = 100*3 = 300, which is the same pattern as the table.
Hope this helps!
