Answer:
Equation: 3(1.25) + 3(2.00)=M
answer:9.75
Step-by-step explanation:
Given:Price of one taco = x; price of 2 tacos = 2xPrice of salad = $2.50Sales tax = 8% of the combined price of two tacos and a salad, namely .08(2x + 2.50)Tip = constant fee = $3.00Total bill = $13.80 Therefore the equation becomes
2x + 2.50 + .08(2x + 2.50) + 3 = 13.80 Solutions: 2x + 2.50 + .16x + .20 + 3 = 13.80 (using the distributive property to multiply 2x and 2.5 by .08).2.16x + 2.70 + 3 = 13.80 (combining like terms)2.16x + 5.70 = 13.80 (combining like terms)2.16x + 5.70 = 13.80 - 5.70 (subtraction property of equality)2.16x = 8.10x = 8.10/2.16 = 3.75 (division property of equality)
The cost of a single taco is $3.75
Answer:
Step-by-step explanation:
Given that X - the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.
Height of male pilot = 74.2 inches
We have to find the percentile
X = 74.2
Corresponding Z score = 74.2-72.6 = 1.6
P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%
i.e. only 5% are below him in height.
Thus the malepilot is in 5th percentile.
Answer: 22% of the pages are filled up
Step-by-step explanation: 900/9= 100 78% of 100 is 78
22+78=100 therefore reaching 100 percent. since 78% is empty that means 22% is being used.
Answer:
The probability is 5/11
Step-by-step explanation:
Let's call V the event that the letter taken at random is a vowel.
Let's call E the event that the man is English and A to the event that the man is American.
If 40 percent of the English-speaking men at the hotel are English means P(E)=0.40 and 60 percent are Americans means P(A)=0.60
In ''color'' we have 2 vowels out of 5 letters so P(V/A)=2/5
In ''colour'' we have 3 vowels out of 6 letters so P(V/E)=3/6=1/2
P(E/V)=P(E∩ V)/P(V)
P(V)=P(V|E)P(E) +P(V|A)P(A)
P(V)=(1/2)0.40+(2/5)0.60=0.44
P(E∩V)=P(V|E)P(E)=(1/2)0.40=0.20
P(E/V)=0.20/0.44=0.45454545=5/11
