You can use a method called unit analysis to solve this problem. You will use it many times in your education later on.
Solve
Now sort out the numbers in the numerator and those in the denominator and multiply them together.
<em><u>Numerator</u></em> 28 * 5280 * 1 * 1 = 147840
<em><u>Denominator:</u></em> 60 * 60 = 3600
Now divide the numerator by denominator
Answer = 147840 / 3600 = 41.1 Feet / second
28 miles per hour = 41.1 feet / second
Answer: number 1
Step-by-step explanation:
number 1
Answer:
- 3/4
- 4/13
- 7/26
- 2/13
- 5.52
Step-by-step explanation:
<u>(a)</u>
- Probability (A heart or a black card) = 13 + 26 / 52
- Probability (A heart or a black card) = 39/52
- Probability (A heart or a black card) = 3/4
<u>(b)</u>
- Probability (A heart or a jack) = 13 + 3 / 52
- Probability (A heart or a jack) = 16/52
- Probability (A heart or a jack) = 4/13
<u>(c)</u>
- Probability (A heart and the ace of clubs) = 13 + 1 / 52
- Probability (A heart and the ace of clubs) = 14/52
- Probability (A heart and the ace of clubs) = 7/26
<u>(d)</u>
- Probability (A 9 or a jack) = 4 + 4 / 52
- Probability (A 9 or a jack) = 8/52
- Probability (A 9 or a jack) = 2/13
<u>(e)</u>
- Probability (The 9 of hearts or a jack) = 1 + 4 / 52
- Probability (The 9 of hearts or a jack) = 5/52
B.
Mean: 208.08
Median: 224.4
Mode: 122.4
Range: 183.6
First, we can make it easier by rearranging them from least to greatest in proper numerical form.
$120, $120, $220, $260, $300
Mean: (120 + 120 + 220+ 260 + 300)(1/5)=1020
1020 x 1.02( tax rate) = 1040.4
1040.4/5= 208.08
Median: %220 x 1.02= 224.4
Mode: 120 x 1.02 = 122.4
Range: (300 x 1.02)-(120 x 1.02)= 306-122.4
306 - 122.4 = 183.6
Answer:
Jenny swam more laps.
Step-by-step explanation:
Lets take this step by step. If Edith swam fewer laps than Shira but more than Gemma, then G < E < S. If Jenny swam more than Shira, then that means Gemma swam the fewest, then Edith, then Shira, and finally Jenny who swam the most laps.
