Step-by-step explanation:
3 girls:7 boys
50 students total
You have to multiply 7 by 5 to get 35
If you already multiplied one side by five, then you have to multiply the other side by five
3 times 5 is 15
15 + 35 = 50
So the
Answer is
35 boys
Answer:
42666 cases
Step-by-step explanation:
P = (Marginal Loss)/ (Marginal Loss + Marginal Profit)
P = (35)/(35+15) = 0.7
Considering a normal distribution we can find the corresponding z value by P = 0.7 (which represented the shaded area under the curve)
z = 0.5244
z = (X - Mean Sales)/Standard Deviation
-0.5244 = (X - 45000)/4450
X = 42666.42 ≅ 42666
Answer:
Phrase : "the product of 19 and a number"
Mathematical expression : 19A
Step-by-step explanation:
Phrase : "the product of 19 and a number"
The product of two numbers a and b can be written as a x b =ab
<u>To find Mathematical expression
</u>
Let A be a number,
The product of number with 19 can be written as
19 x A = 19A
Therefore the given phrase "the product of 19 and a number" as a mathematical expression =19A
