Answer:
25.5 days
Step-by-step explanation:
Mean number of days (μ) = 22 days
Standard deviation (σ) = 6 days
Z-score for the 72nd percentile (according to tabulated values) = 0.583
The z-score for any number of days, X, is determined by:
The value of X that is greater than 72% of the trial times is:
Therefore, 72% of all of these types of trials are completed within 25.5 days.
X - (-20) = 5
When you subtract a negative, change it to addition:
X + 20 = 5
Subtract 20 from both sides:
X = -15
21 is a rational number because it is an integer, which can be converted into a fraction.
<u>Step-by-step explanation:</u>
When a denominater and numerator are integers and gives a quotient then it is a rational number.
21/1, where 21 is denominator and 1 is numerator the quotient is 21. Therefore 21 is a rational number which can also be considered as a ratio.
Step-by-step explanation:
1. ΔABC=ΔCDE: a) according to the condition BC=CD and AC=CE; b) m∠(BCA)=m∠(DCE).
2. if ΔABC=ΔCDE, then m∠(BAC)=m∠(DEC) and m∠(ABC)=m∠(CDE).
3. if m∠(BAC)=m∠(DEC), then AB || DE (or if m∠(ABC)=m∠(CDE), then AB || DE).
Answer:p=69
Step-by-step explanation:
Let's solve your equation step-by-step.
3666=39(p+25)
Step 1: Simplify both sides of the equation.
3666=39(p+25)
3666=(39)(p)+(39)(25)(Distribute)
3666=39p+975
Step 2: Flip the equation.
39p+975=3666
Step 3: Subtract 975 from both sides.
39p+975−975=3666−975
39p=2691
Step 4: Divide both sides by 39.
39p
/39 = 2691
/39
