Answer:
x = 11
Step-by-step explanation:
Median = The middle value of the set
There are 8 data values in the data set. You can split it up by 2 in order to get 4 and 4. There are two middle numbers that make up the median
3 4 7 9 x 12 14 18
We know that in order to find the median, we have to divide the two numbers by 2. If the median is 10, 10 by 2 equals 20. 9 plus 11 equals 20,
3 4 7 9 11 12 14 18
x = 11
Answer:
22
Step-by-step explanation:
Given
2t + 4s ( substitute t = 5, s = 3 into the expression )
= 2(5) + 4(3)
= 10 + 12
= 22
Answer:

Step-by-step explanation:
We will use the co-function identity for sine, where:

Since sin(21)=0.358=cos(x). This means that:

Solve for x. Add x to both sides:

Subtract 21 from both sides:

Hence:
