A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled.

Which statement shows the meaning of the driver’s equation? Select two options.
Three dollars added to $0.50 is the same as $9.50.
Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents.
The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50.
The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Answer:

Step-by-step explanation:

[tex] \csc \: x = \frac{1}{ \sin \: x } \\ \csc(0) = \frac{1}{ \sin(0) } \\ if \: \sin(0) = 0.788 \: so \\ \csc(0) = \frac{1}{0.788} \\ \\ \csc(0) = 1.27[/tex]

Answer: -0.03

sqrt ((0.12 (0.88) / 200) + (0.15)(0.85)/200)

Step-by-step explanation:

The mean of the sampling distribution of the difference in sample proportions is -0.03, and the standard deviation is 0.0321.

A standard deviation (σ) is a measure of the distribution of the data in reference to the mean.

The proportion of lockout help requests in the summer population is 12% or 0.12, and the proportion in the winter population is 15% or 0.15. The sample sizes are both 200.

Using these values, we can calculate the mean and standard deviation of the sampling distribution of the difference in sample proportions:

Mean = p₁ - p₂ = 0.12 - 0.15 = -0.03

Standard deviation = √[ (p₁ (1 - p₁) / n₁) + (p₂ (1 - p₂) / n₂) ]

= √[ (0.12 (1 - 0.12) / 200) + (0.15 (1 - 0.15) / 200) ]

= √[ (0.000504) + (0.000525) ]

= √[ 0.001029 ]

= 0.0321

Therefore, the mean of the sampling distribution of the difference in sample proportions is -0.03, and the standard deviation is 0.0321.

The weight of the third book is approximately 5.33 grams.

According to the given information:

The average weight of the 3 books is 3 grams.

To find the average weight, we sum up the weights of all the books and divide by the total number of books:

(1/3 + 5/2 + x) / 3 = 3

Now we can solve this equation to find the weight of the third book:

(1/3 + 5/2 + x) = 3 * 3

(1/3 + 5/2 + x) = 9

(1 + 15 + 6x) / 6 = 9

(22 + 6x) / 6 = 9

22 + 6x = 54

6x = 54 - 22

6x = 32

x = 32 / 6

x ≈ 5.33

Therefore, the weight of the third book is approximately 5.33 grams.

Answer:

$120

Step-by-step explanation:

Set the cost of the article pre-tax as x.

x + 0.15x = 138

1.15x = 138

x = 138/1.15

x = $120

Answer: the cost of the article without  taxes is $120.

The required cost of the article without  taxes is $120.

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

Thus, unit price of something is price of 1 thing.

Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

We have been given the cost of an article including 15% for taxes is $138.00.

Lets Set the cost of the article pre-tax as x.

x + 0.15x = 138

1.15x = 138

x = 138/1.15

x = $120

Therefore, the cost of an article including 15% for taxes is $138.00. the cost of the article without  taxes is $120.

Answer:

[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]  

Step-by-step explanation:

It is given that a meteorologist is using a Doppler radar to find out the distance of the storm as it passes using a polar grid.

The origin of the radar screen is its center.

And the distance between each ring is 10 miles from the center.

So let :

r = radius

h and k = be the coordinates of the center.

So the equation of a circle is :

[tex]$(x-h)^2+(y-k)^2= r^2 $[/tex]

Now the equation of the fourth circle when the radius changes by 10 miles is :

[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]  

Answer:

h = 5 ft, which does not make sense since a 5 ft ceiling is kind of small

Step-by-step explanation:

b = 10 ft and h = b / 2, so h = 10/2, h = 5 ft

Binomial approximation to the normal:

Binomial distribution has n trials, with p probability.

If

[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], it can be approximated to the normal distribution.

Assume the probability that a given student will not pass their college placement exam is 98%.

This means that [tex]p = 0.98[/tex]

134 students:

This means that [tex]n = 134[/tex]

Necessary conditions:

[tex]np = 134*0.98 = 131.32 \geq 10[/tex]

[tex]n(1-p) = 134*0.02 = 2.68 < 10[/tex]

Since the necessary condition n(1-p) < 10 is not satisfied, the answer is No, given by option b.
