Answer:
375
Step-by-step explanation:
"817 tickets were sold"
a and s are the number of adults and students, respectively.
a+s = 817
s = 817-a
"67 more student tickets sold than adults"
s = a+67
817-a = a+67
750 = 2a
a = 375
375.
817 minus 67 = 750÷2=375

Solve the system of equations.
-5x + 4y = 3
X = 2y - 15
Answer:
x=9
y=12
Step-by-step explanation:
. Substitute the given value of x into the equation so... -5(2y-15)+4y=3
. y=12
. Substitute the given value of y into the equation x=2y-15 so... x=2 x 12-5
. x=9
.The possible solution of the system is the ordered pair (x,y) so... (x,y)=(9,12)

You want to estimate the mean number of sentences in a magazine advertisement.How many magazines advertisements must be included in the sample if you want to be 95% confident that the sample mean is within one sentence of the population mean
Complete question:
You want to estimate the mean number of sentences in a magazineadvertisement. How many magazine advertisements must beincluded in the sample if you want to be 95% confident that thesample mean is within 1 sentence of the population mean ? (sigma =5)
Answer:
96
Step-by-step explanation:
We have level of confidence = 95%
Alpha = 1-0.95
= 0.05
Alpha/2 = 0.025
Z-alpha/2 = 1.96
E = margin of error = 1
For this question the formula to derthe sample size is given as:
n = [(Za/2 x sigma)/E]²
n = (1.96 x 5/1)²
n = 9.8²
= 96.04
So 96 magazines advertisement must be included in the sample to be 95% confident.
Estimate 43,059 ÷ 62 = 2. Estimate 11,117 ÷ 96 = 3. Estima.24,743 ÷ 54 =

. The length of the long-distance calls made by the employees of a company followed a normal distribution with a mean of 6.5 minutes and a standard deviation of 2 minutes. a. What is the probability that a call lasts less than 4 minutes
Answer:
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25) = 0.1056
Step-by-step explanation:
Step(i):-
Given mean of the population = 6.5 minutes
Given standard deviation of the Population = 2 minutes
Let 'X' be the random variable in normal distribution
Given X = 4
[tex]Z= \frac{x-mean}{S.D} = \frac{4-6.5}{2} = -1.25[/tex]
Step(ii):-
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25)
= 1-P(z>1.25)
= 1 - ( 0.5 +A(1.25)
= 1-0.5 - A(1.25)
= 0.5 - 0.3944 ( from normal table)
= 0.1056
Final answer:-
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25) = 0.1056

Answer:
3 cm
Step-by-step explanation:
First, we have to understand what happens if two shapes are similar. When two shapes are similar, the angles are equal in both. This means the sides will be in the same ratio from one shape to another.
[tex]\frac{7.2}{t}=\frac{9.6}{4}[/tex]
Using the equation above, we can find t. We use cross multiplication (ad = bc)
7.2 * 4 = 9.6t
9.6t = 28.8
t = 3 cm
