A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 15 bulbs?

Answers

Answer 1

Answer:

2

Step-by-step explanation:

Given that:

Flawed bulbs = 4

Not flawed = 26

Total examined = (flawed + not flawed)

Total examined = (4 + 26) = 30

P(flawed) = flawed / total

P(flawed) = 4 / 30 = 0.1333333

If 15 is examined :

Expected number of flawed bulbs :

(4/30) * 15 = 2

Which expressions are equivalent to − 90 − 60 w?

Answers

Answer:

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Using distributive property:

A : -30(3+2w)  =  -90 - 60w          : equivalent to -90 - 60w

B : (-9-6w) ⋅ 10  = -90 - 60w          : equivalent to -90 - 60w

C : -3(30 - 20w)  = -90 + 60w       : NOT equivalent to -90 - 60w

D : (6 + 4w)×15  = 90 + 60w          : NOT equivalent to -90 - 60w

E : −20(4.5 + 3w) = - 90 - 60w     : equivalent to -90 - 60w

SO THAT MEANS

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Bryan’s hockey team is purchasing jerseys. The company charges $250 for a one-time set-up fee and$23 for each printed jersey. Which expression represents the total cost of x number of jerseys for the team?
1) 23x
(2) 23x + 250
(3) 23 + 250x
(4) 23(x + 250)

Answers

Answer:

(2) 23x + 250

Step-by-step explanation:

We are given that

Company charges  for one-time set up=$250

Charge for each printed jersey=$23

x=Number of jerseys for team

We have to find the expression which represents the total cost of x number of jerseys for the team.

Total cost of x jerseys printing=[tex]23\times x[/tex]

Total cost of x jerseys printing[tex]=23x[/tex]

Therefore,

Total cost of x number of jerseys for the team=250+23x

Hence, option (2) is true.

(2) 23x + 250

Find the value of y = 500 -25x
for x = { -3, 2, 5}

Answers

Answer:

575, 450 and 375

Step-by-step explanation:

Find the value of y = 500 -25x

for x = { -3, 2, 5}

Given the function y = 500-25x

When x = -3.

y = 500-25(-3)

y = 500+75

y = 575

When x = 2

y = 500-25(2)

y = 500-50

y = 450

When x = 5

y = 500-25(5)

y = 500-125

y = 375

Hence the required values are 575, 450 and 375


The diagram below models the diameter of the bicycle wheel
21.75
Which of the following is closest to the distance of the length when the bicycle wheel
makes 1 revolution?
A7 inches
B 25 inches
C34 inches
D69 inches


Can anyone help me!!

Answers

Answer: (21.75 / 2) * 2 * pi = 68.42...in, answer D.

Explanation: one revolution from a wheel will be a 360 degree rotation, meaning that if you had laid your finger on the outside of the wheel as it made its full rotation, your finger would have touched the entire circumference of the wheel. Thus, we can represent the length of 1 revolution as the circumference. Thus we take the diameter, and divide it by 2 to get the radius. Then we simply multiply by 2 * pi * r (r = radius). This is the formula for the circumference of a circle.

A surfboard has an original price of $259. It is on sale for 55% off the original price.

Answers

I'm not sure what answer you need for this question?
original price: 259
sale: 55% off
55%=0.55
so 259×0.55=142.45
142.45 is the 55% of the original price
259－142.45=116.55
116.55 is the price after sale.
hope this would help. (*^ω^*)/

Answer:

$116.55

Step-by-step explanation:

If original price= $259

And sale= 55% off original price

Then price after sale=(100%-55%) of $259

Working:

100%-55%=45% or [tex]\frac{45}{100}[/tex]

45% of $259 or [tex]\frac{45}{100}[/tex] x [tex]\frac{259}{1}[/tex]= $116.55
