Probability of having at least 1 boy = 1 - the probability of having ALL girls.
P(5 girls) = (1/2)⁵ = 1/32
P(At least 1 boy) = 1 - 1/32 = 31/32
Answer: 31/32
Answer:
2 feet by 1.25 feet
Step-by-step explanation:
The arcade floor has dimensions 120 ft by 75 ft.
The scale of the drawing on grid paper is 1 in : 5 feet. This is a reduced scale. This means that the size of the arcade floor was reduced in the drawing.
Let us simply the ratio 1 in : 5 feet.
1 foot = 12 inches
=> 5 feet = 5 * 12 = 60 inches
The ratio can be rewritten as 1 in : 60 in = 1 : 60.
Hence, multiply the individual dimensions of the arcade floor by
.
120 feet will be:
120 *
= 2 feet
75 feet will be:
75 *
= 1.25 feet
Therefore, the dimensions of the scale drawing are 2 feet by 1.25 feet.
The length of rectangle is 15 feet and width is 7 feet.
Step-by-step explanation:
Given,
Width of rectangle = w
Length of rectangle = 2w+1
Perimeter = 44 feet
Perimeter = 2(Length+Width)

Dividing both sides by 6

The width of rectangle is 7 feet.
Length of rectangle = 2(7)+1 = 14+1 = 15 feet
The length of rectangle is 15 feet and width is 7 feet.

Answer:
84 ft^2.
Step-by-step explanation:
Use Pythagoras to find the value of h:
25^2 = h^2 + 7^2
h^2 = (25-7)(25+7)
h^2 = 576
h = √576 = 24
Area = 1/2 * 7 * 24
= 84.
The required number line that shows all of the possible

<h3>Inequalities and number line</h3>
From the given question, we have that water freezes when its temperature is no more than 32 °F
The statement no more than 32 °F shows that the temperature cannot be greater than 32 but less than or equal to 32. This is written mathematically as;
t ≤ 32.
We are to select the number line that shows all of the possible temperatures. The required number line that shows all of the possible
temperatures is option A.
