Answer: he must work for at least 26.32 hours
Step-by-step explanation:
Let x represent the number of hours that Hayden works as a life guard.
Hayden earns $9.50 per hour as a lifeguard. This means that the amount that he earns for working for x hours would be
9.5x
He earns a bonus of $50.00 for taking a training course. If he takes this bonus cost, the amount that he would earn for working for x hours is
9.5x + 50
Therefore, the number of hours that he must work to earn at least $300.00 would be
9.5x + 50 ≥ 300
9.5x ≥ 300 - 50
9.5x ≥ 250
x ≥ 250/9.5
x ≥ 26.32
Answer: option 1 is the correct answer
Step-by-step explanation:
Number of times for which the die was rolled is 360. It means that our sample size, n is 360.
The probability of rolling a 5 or a 6 is 1/3. It means that probability of success,p = 1/3. The probability of failure,q is
1 - probability of success. It becomes
1 - 1/3 = 2/3
The formula for standard deviation is expressed as
√npq. Therefore
Standard deviation = √360 × 1/3 × 2/3
= √80 = 8.9443
Standard deviation is approximately 8.9
You multiply 0.4 by 4.2 and that equals 1.68 so sumeet uses 1.68 gallons of gas in 4.2 hours.
5280 feet in 1 mile
3600 seconds in an hour
58(5280) / 3600 = 306240/3600 = 85.06 ft per sec or if u need it rounded, it is 85.1
Answer:
46.2 square inches
Step-by-step explanation:
A parallelogram is a quadrilateral (4 sided closed figure) with 2 pair of parallel sides.
The diagram shown is a parallelogram.
Top and Bottom are parallel lines,
both sides are parallel lines (left and right).
The area for a parallelogram is given by:
Area = Base * Height
In the given figure, the base is clearly given as 4.2 inches
The height (perpendicular distance from base) is given as 11 inches.
<em><u /></em>
<em><u>So, basically we do not need the 11.7 inches length of side given.</u></em>
<em><u /></em>
Now, lets compute the area:
Area = base * height = 4.2 * 11 = 46.2 square inches
