Let x be the number of pastries they must sell.
$3.50x≥140
This inequality states that for the number of pastries at 3.50 dollars each must be greater than or equal to 140. Solve for x.
Answer:
n = 18
Step-by-step explanation:
The formula for angle sum of a polygon is S = 180 (n - 2), where S is the sum and n is the sides.
We are given that the sum is 2880, and are trying to find n.
Simply sub in S = 2880,
2880 = 180 (n - 2)
Divide by 180 to get (n - 2) by themselves on the right side,
16 = n - 2
Now add 2 to the other side to get n by itself
18 = n
n = 18

Answer:
0.01596
Step-by-step explanation:
A scientist claims that 8% of the viruses are airborne
Given that:
The population proportion p = 8%
The sample size = 477
We can calculate the standard deviation of the population proportion by using the formula:




The required probability can be calculated as:


= P(Z < -2.41) + P(Z > 2.41)
= P(Z < -2.41) + P(Z < -2.41)
= 2P( Z< - 2.41)
From the Z-tables;
= 2 ( 0.00798
= 0.01596
Thus, the required probability = 0.01596
