#10. If 5 books cost $20 that means every book is $4. So 4 books would be 4x4= $16
#11 5 in =3 miles. There would be 3 sets of 3 miles in the 9 miles. So 5x3= 15
Answer:
No. The method is not fair.
<span>The
probability of pulling a gold or a silver for the first time is 1/10. The
probability of getting the same color the second time is 1/9. The probability
of getting a different color on the second pullout is still 1/10. Therefore,
the chance that same colors will be
pulled out is higher than that of different colors. Betty has an advantage in the drawing by 1.1%.</span>
Solution:
Probability of same color:
1/10+1/9
9/90+10/90
21.1%
Probability of different colors
1/10+1/10
2/10
20%
<span>21.1%-20%=1.1%</span>
Answer:
<h2> There is no slope.</h2>
Step-by-step explanation:
It means that for a line passing through two points to have the slope, the x-coordinates of these point have to be different.
(-4, 0) and (-4, -10) means x₁ = x₂ = -4, <u>so there is no slope.</u>
{the line is parallel to Y-axis, and has an equation: x=-4}
Answer:
73.3
Step-by-step explanation:
cos(39)= 57/x
x= 57/cos(39)
x=73.3
Answer:
: A semi-circle is half of a circle. Area of semi-circle formula is derived from the formula of a circle. Hence the area of a semi-circle is just the half of the area of a circle. How to Find the Area of a Semicircle To find the area of a semi-circle, you need to know the formula for the
