Answer:
The value of P(z<1.00)=0.8413
Step-by-step explanation:
Using a standard normal table, the area under the standard normal curve below the given value of z=1 is:
z <u> .00</u> .01
0.9 0.81594 0.81859
<u>1.0</u> <u>0.84134</u> 0.84375
1.1 0.86433 0.86650
P(z<1.00)=0.84134
Rounded to 4 decimal paces
P(z<1.00)=0.8413

Answer:
Step-by-step explanation:
Let a and c represent the costs of adult and child tickets, respectively. Then the two purchases can be described by ...
2a +4c = 46 . . . . . . Sue's purchase
4a +7c = 86 . . . . . . Karen's purchase
__
The system can be solved by subtracting the second equation from twice the first:
2(2a +4c) -(4a +7c) = 2(46) -(86)
c = 6 . . . . . . . simplify
We can substitute this value into half the first equation to find "a".
a +2(6) = 23
a = 23 -12 = 11
The cost of 1 adult ticket is $11; the cost of one child ticket is $6.
Answer:
The expression that represents Capri’s age is a + 4.
The expression that represents Portia’s age is a – 5.
Step-by-step explanation:
The expression that represents Capri's age is a + 4.
The expression that represents Portia's age is a -5.
To write an equation for this scenario, Capri's age needs to be equal to Portia’s age
The equation used to represent this scenario is a + a + 5 + 2 - 4 = 38.
Solving this equation will give Aziza's age.
Aziza'a age = a
Portia age = a - 5
Capri's age = 4 + a
a + a - 5 + 4 + a = 38
Answer:
The sum of 29 and the number the friend collect (a) is 56.
