Answers
Answer: $25.41
Convert the percentage into a decimal, and then multiply that decimal by the total price to find the tip. Subtract the tip amount from the total price to find the price before the tip.
15 ÷ 100 = 0.15
15% of 29.90 = 0.15 · 29.90 = 4.48500 ≅ $4.49
$29.90 - $4.49 = $25.41
∴ the price before tip, b, of Mr. Johnson's lunch is $25.41.

Answers
Answer:
[tex]x=\dfrac{d}{(5+10f)}[/tex]
Step-by-step explanation:
The given equation is :
d = 5x + 10xf
We need to solve the above equation for x.
Taking x common from RHS,
d=x(5+10f)
Dividing both sides by (5+10f),
[tex]x=\dfrac{d}{(5+10f)}[/tex]
Hence, this is the required value of x.

What are the y-intercept and the x-intercept:
y=4x-4
Answers
Answer:
X=1
Step-by-step explanation:
0=4x-4
-4x=-4
-4x/-4=-4/-4
x=1
y = 4(0)-4
y = 0-4
y = -4
the y intercept is -4
to find the x intercept, do the same thing but with y (set y to 0)to get:
0 = 4x - 4
4x = 4
x = 1
the x intercept is 1
Ally works in a shop for $18 per hour. She is not allowed to work more than 40 hours a week but has to work at least 20 hours. State a reasonable domain for this problem.
Answers
Answer:
Hi there!
The domain is:
20<=x<=40
Step-by-step explanation:
This states that:
x>=20
x<=40
Which fits the problem!
Hope this helps
For a given function f(x) we define the domain as the set of possible values of x that we can use in the function.
Here we will find that the domain is D: [20h, 40h]
We know that Ally wins $18 per hour, and she has two restrictions:
She cant' work more than 40 hours.
She needs to work at least 20 hours.
Then her weekly salary can be written as:
s(x) = $18*x
Where x is the number of hours that she works each week.
With the above restrictions we have:
20h ≤ x ≤ 40h
Then the domain is:
D: [20h, 40h]

Help please
Answers
Answer:
-44
Step-by-step explanation:
So you want to plug 2 in for t, so the equation should now look like:
[tex]2^{2}[/tex] - 44 - 4
No all you have to do is solve
[tex]2^{2}[/tex] = 4
4 - 44 = -40
-40 - 4 = -44
Answer:
-44
Step-by-step explanation:
t=2, t² - 44 - 4
1. substitute in the value to the variable: 2² - 44 - 4
2. using PEMDAS, solve the equation: 2² - 44 - 4 = 4-44-4 = -40-4= -44
(evaluate the exponent, then subtract)

Mario is walking away from a motion detector at a rate of 1.5 feet per second. He started recording his distance from the motion detector when he was 2 feet in front of the motion detector. Fill in the blank in the sentence below. Mario is 11 feet from the motion detector at ____ a seconds
Answers
Answer:
6 seconds
Step-by-step explanation:
Initial distance of Mario from motion detector = 2 ft
Speed of Mario = 1.5 ft/sec
Total distance of Mario from motion detector = 11 ft
Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft
Given that:
Distance = 9 ft
Speed = 1.5 ft/sec
Formula:
[tex]Distance = Speed \times Time[/tex]
[tex]\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}[/tex]
So, at 6 seconds, Mario will be 11 ft from the motion detector.

5.2.36-T
When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan: Randomly select and test 41 batteries and determine whether each is within specifications. The entire shipment is
accepted if at most 3 batteries do not meet specifications. A shipment contains 7000 batteries, and 3% of them do not meet specifications. What is the probability that this whole shipment will be accepted? Will almost
all such shipments be accepted, or will many be rejected?
The probability that this whole shipment will be accepted is 0.9660
(Round to four decimal places as needed)
The company will accept 96.6 % of the shipments and will reject 34% of the shipments, so almost all of the shipments will be accepted
(Round to two decimal places as needed.)
Answers
Answer:
Probability that the whole shipment will be accepted = 0.9660
96.60% of the shipment will be accepted
Almost all the shipments will be accepted
Step-by-step explanation:
We are given;
n = 41
p = 3% = 0.03
x = 3
This is a binomial probability question and we will use the formula;
P(X = x) = [n!/(x!(n - x)!)] × p^(x) × (1 - p)^(n - x)
The probability that the whole shipment will be accepted is given by the form;
P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)
P(3) = [41!/(3!(41 - 3)!)] × 0.03³ × (1 - 0.03)^(41 - 3)
P(3) = 0.09046
P(2) = [41!/(2!(41 - 2)!)] × 0.03² × (1 - 0.03)^(41 - 2)
P(2) = 0.22496
P(1) = [41!/(1!(41 - 1)!)] × 0.03¹ × (1 - 0.03)^(41 - 1)
P(1) = 0.36373
P(0) = [41!/(1!(41 - 0)!)] × 0.03^(0) × (1 - 0.03)^(41 - 0)
P(0) = 0.28684
Thus;
P(X ≤ 3) = 0.28684 + 0.36373 + 0.22496 + 0.09046
P(X ≤ 3) = 0.96599 ≈ 0.9660
It means that 96.60% will be accepted
