Answer:

Step-by-step explanation:

we know that 1 lb=16oz

16 oz almonds = costs 8 dollars , we divide the cost to oz

8/16=0.5 dollars / oz

4.10/0.5=8.2 oz

for 4.10 dollars you buy 8.2 oz

Answer:

12

Step-by-step explanation:

This is a fraction equal to

30 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

30 miles ÷ 2.5

2.5 hours ÷ 2.5

=  

12 miles

1 hour

=  

12 miles

hour

= 12 miles per hour

Answer: 1.5x

Step-by-step explanation:

If the figure dilates by 1.5 times it will increasingly do the same with the perimeter. It keeps the same ratio of 1.5x.

Ex: If a side of the figure was originally 10 and the dilation factor is 1.5 the side now with be 15. This goes for all sides.

Answer . m= -1/8

Step-by-step explanation:

The perpendicular slope is the negative reciprocal. Meaning that the numerator and denominator are switched and the sign of the slope becomes the opposite. (if the slope was -8, then the perpendicular slope would be 1/8)

Answer: y=0.5x-6. She forgot the y-intercept

Step-by-step explanation: use the slope formula to get the slope of 0.5 and just add in the y-intercept of -6 since:

y=mx+b

m=slope

b=y-intercept

Answer:

y = 0.5x - 6

Step-by-step explanation:

[tex]since \: there \: are \: two \: points \: \\ m = \frac{y2 - y1}{x2 - x1} [/tex]

[tex]m = \frac{ - 5 - ( - 7.5)}{2 - ( - 3)} = \frac{2.5}{5} = \frac{1}{2} \: or \: 0.5[/tex]

Standard form of slope-intercept:

y = mx + b

wherein m is the slope and b is the y-intercept.

Let's substitute all values into the equation

[tex]y = 0.5x - 6[/tex]

Answer:

16

Step-by-step explanation:

2500/150=16 2/3

but we dont want 2/3 of a person so just ignore that part

im in a hurry sorry

Answer:

16

Step-by-step explanation:

assuming that you can go up to 2500, simply multiple until you reach your target of 2500, i did 150 x 16 to get 2400, 100 less than 2500, meaning it would be safe and one more wouldn't.

Answer: 18

Step-by-step explanation: Add them all together to get the answer to the equation <3

Answer:

a) 0.1558 = 15.58% probability of finding 4 cars with the defect in a random sample of 7000 cars.

b) 0.1557 = 15.57% probability of finding 4 cars with the defect in a random sample of 7000 cars. These probabilities are very close, which means that the approximation works.

Step-by-step explanation:

Binomial distribution:

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

To use the Poisson approximation for the binomial, we have that:

[tex]\mu = np[/tex]

1 in every 2500 automobiles produced has a particular manufacturing defect.

This means that [tex]p = \frac{1}{2500} = 0.0004[/tex]

a) Use a binomial distribution to find the probability of finding 4 cars with the defect in a random sample of 7000 cars.

This is [tex]P(X = 4)[/tex] when [tex]n = 7000[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 4) = C_{7000,4}.(0.0004)^{4}.(0.9996)^{6996} = 0.1558[/tex]

0.1558 = 15.58% probability of finding 4 cars with the defect in a random sample of 7000 cars.

(b) The Poisson distribution can be used to approximate the binomial distribution for large values of n and small values of p.

Using the approximation:

[tex]\mu = np = 7000*0.0004 = 2.8[/tex]. So

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 4) = \frac{e^{-2.8}*(2.8)^{4}}{(4)!} = 0.1557[/tex]

0.1557 = 15.57% probability of finding 4 cars with the defect in a random sample of 7000 cars. These probabilities are very close, which means that the approximation works.

Answer:

1: Yes they are both equivalent because 48/8 is 6 and 24/4 is 6.

2: They would score 750 points because you divide 150 by 3 and get 50, then you multiply 50 by 15 and get 750!

Answer:

1 1/3 gallons of shampoo

Step-by-step explanation:

The above question is calculated as:

5 hairdressers = 6 2/3 gallons of shampoo

1 hairdresser = x gallon

We cross Multiply

5 hair dressers × x gallon = 6 2/3 gallons × 1 hair dresser

x gallon = 6 2/3 gallons × 1 hair dresser/5 hair dressers

x gallons = 6 2/3 gallons ÷ 5

x gallons = 20/3 gallons ÷ 5

= 20/3 × 1/5

= 4/3

= 1 1/3 gallons of shampoo

Therefore, each hair dresser would receive 1 1/3 gallons of shampoo

Answer:

20.5

Step-by-step explanation:

20 + 21 = 41.   Divide 41 by 2 than you get 20.5.

The first quartile of the given data set is 20.

Here,

To find the first quartile of a data set, we first need to arrange the data in ascending order.

Then, we can calculate the position of the first quartile using the formula:

Position of the first quartile (Q1) = (n + 1) / 4

where n is the number of data points in the data set.

Given data set: 15, 18, 20, 21, 23, 24, 26, 29, 34, 37, 40

Arranging the data in ascending order: 15, 18, 20, 21, 23, 24, 26, 29, 34, 37, 40

Now, let's calculate the position of the first quartile:

n = 11 (since there are 11 data points in the data set)

Position of the first quartile (Q1) = (11 + 1) / 4 = 12 / 4 = 3

The first quartile (Q1) is the value at the 3rd position in the ordered data set, which is 20.

So, the first quartile of the given data set is 20.
