Step-by-step explanation:

if the equation was y = -2x + 18 then the graph would look like a staircase and the graph looks linear

The statements about the box plot in Figure A2 are analyzed and determined to be true or false.

The graph in Figure A2 is a box plot. Let's go through each statement and determine if it is true or false.

A. Twenty-five percent of the data are at most five: True. The box extends from the first quartile (Q1) to the third quartile (Q3), which represents the middle 50% of the data. The line inside the box is the median, and the whiskers extend to the minimum and maximum values. In this case, the box goes up to five, indicating that 25% of the data are at most five.

B. There is the same amount of data from 4-5 as there is from 5-7: False. The box plot shows the range of values within the quartiles. In this case, the range from 4-5 is smaller than the range from 5-7, indicating that there is more data in the latter range.

C. There are no data values of three: True. The box plot does not have any outlier points at the value of three, indicating that there are no data values at that point.

D. Fifty percent of the data are four: False. The median value in the box plot is the value that divides the data into two equal halves. In this case, the median is not at four, so 50% of the data are not equal to four.

Answer:

3/20 of the pizza

Step-by-step explanation:

To find how much she eats in one minute, you have to change the fraction into a decimal, which is 0.75, and divide that by 5. Once you've done that, you get 0.15 of the pizza in a minute. this can be simplified into the fraction 3/20.

Answer:

3/20

Step-by-step explanation:

If she can do 3/4 per 5 minutes, the amount in 1 minute is 1 fifth of 3/4, so multiply 3/4 by 1/5 to get 3/20.

Step-by-step explanation:

[tex] \angle JML \:and\:\angle LMN [/tex] Linear pair angles or straight line angles.

[tex] \therefore \: \angle JML + \angle LMN = 180 \degree \\ \therefore \: 3x + 54 \degree = 180 \degree \\ \therefore \: 3x = 180 \degree - 54 \degree \\ \therefore \: 3x = 126 \degree \\ \therefore \: x = \frac{126 \degree}{3} \\ \therefore \: x = 42\degree \\ [/tex]

The minimum value is 19, maximum is 37, median is 28.5, first quartile is 23.5, and third quartile is 33.5. These measures are calculated by organizing the data in ascending order and finding the middle and approximated middle values of the data set and its halves.

First, let's arrange your data in ascending order: 19,20,21,22,23,24,26,27,28,29,30,31,32,33,34,35,36,37. There are 18 data points here.

The minimum value is 19 and the maximum value is 37.

To calculate the median (the middle number), since we have an even number of data points, we take the average of the 9th and 10th numbers. (28+29)/2 = 28.5.

Now, to find the first quartile (lower median), we look at the median of the lower half of the data (excluding the overall median if it's part of the data). The lower half of the data is: 19,20,21,22,23,24,26,27,28. So, we take the average of 23 and 24 which is 23.5.

For the third quartile (upper median), we look at the median of the upper half of the data. Here it is: 29,30,31,32,33,34,35,36,37. So, we take the average of 33 and 34 which is 33.5.

Answer:

162 mL

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

V = \text{2 oz} \times \dfrac{\text{29.57 mL}}{\text{1 oz}} = \text{ 59.14 mL)

(c) Banana flavouring

V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.93 mL}}{\text{1 tsp}} = \textbf{2.46 mL} }

2.Calculate the total volume

Chlorpheniramine = 100      mL

Lidocaine               =   59.14

Banana flavouring =    2.46          

TOTAL                    = 162      mL

Step-by-step explanation:

law of cosines states that

for sides A B C and angle c opposite to side C,

[tex]C = \sqrt{A^2 + B^2-2ABcos(c)} \\cos(c) = \frac{c^2-a^2-b^2}{-2ab}[/tex]

cos-1(23/45) = b

b = 59

Answer:59

Step-by-step explanation:

C2=a2+b2-2ab cosC

13x13=15x15+6x6-2(15)(6)cosC

169=225+36-180cosC

169=261-180cosC

-92=180cosC

Answer:

log 19 + log 42

Step-by-step explanation:

798 = 2* 3 *7*19

= 19 * 42

log 798 = log (19*42)

Now log ab = log a + log b

So:

log 798 = log 19 + log 42  <-- is equivalent to log 798.

r = - [tex]\frac{12}{7}[/tex]

Step-by-step explanation:

Given that r varies inversely as t , then the equation relating them is

r = [tex]\frac{k}{t}[/tex] ← k is the constant of variation

To find k use the condition t = - 6 when r = - 2, then

- 2 = [tex]\frac{k}{-6}[/tex] ( multiply both sides by - 6 )

12 = k, thus

r = [tex]\frac{12}{t}[/tex] ← equation of variation

when t = - 7, then

r = [tex]\frac{12}{-7}[/tex] = - [tex]\frac{12}{7}[/tex]

Answer: 12 because for each number on the die, you get 2 options: one marble or the other. So if it’s a six sided die, you have 12 possible outcomes. (2 times 6)

You roll a die and pick a marble,  12 outcomes are possible.

The possibility of an event in time is known as probability in mathematics. How frequently does the incidence occur over the course of a specific time period, in plain English?

Given:

You roll a die and pick a marble.

When you roll a die,

you'll get either one marble or another.

So, there are 2 possibilities.

When you roll a die, there 6 possible outcomes.

And the total number of possible outcomes,

= 2 times 6

= 2x 6

= 12

Therefore, 12 outcomes are possible.

Answer:

9x2 – 25 = (3x – 5)(3x + 5)

Step-by-step explanation:

(3x – 5)(3x + 5)

= 9x² + 15x - 15x - 25

= 9x² - 25

Final answer:

The correct equation is 9x² – 25 = (3x – 5)(3x + 5), as it is the factored form of the difference of squares, where 9x² is the square of 3x and 25 is the square of 5.

Explanation:

The equation we are considering is 9x² – 25. We need to determine which of the provided options is a true equality. The equation 9x² – 25 is a difference of squares, which factors as (a² – b²) = (a – b)(a + b). In this case, a is 3x and b is 5 because (3x)² = 9x² and 5² = 25.

Thus, the factored form of the equation 9x² – 25 is (3x – 5)(3x + 5). So, the correct equation from the given options is 9x² – 25 = (3x – 5)(3x + 5).

Answer:

A =153.86 yd^2

Step-by-step explanation:

The area of a circle is given by

A = pir^2

We need to get the radius.  We are given the diameter

r = d/2 = 14/2 =7

A = pi (7)^2

A =49pi

Using 3.14 for pi

A = 49 (3.14)

A =153.86 yd^2

Answer:

a) 95% Confidence interval = (0.026%, 0.037%) to 3 d.p

b) The result of the 95% confidence interval does not agree with the previous rate of such cancer because the value 0.0224% does not lie within this confidence interval obtained.

Step-by-step explanation:

Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample proportion) ± (Margin of error)

Sample proportion = (131/420076) = 0.0003118483 = 0.0312%

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error)

Critical value at 95% confidence interval for sample size of 420,076 is obtained from the z-tables because the sample size is large enough for the properties of the sample to approximate the population properties.

Critical value = 1.960 (from the z-tables)

Standard error = σₓ = √[p(1-p)/n]

n = sample size = 420,076

σₓ = √(0.0003118×0.999688/420076) = 0.0000272421 = 0.0000272

95% Confidence Interval = (Sample proportion) ± [(Critical value) × (standard Error)]

CI = 0.000312 ± (1.96 × 0.0000272)

CI = 0.000312 ± 0.0000534

95% CI = (0.0002586055, 0.0003653945)

95% Confidence interval = (0.000259, 0.000365)

95% Confidence interval = (0.0259%, 0.0365%) = (0.026%, 0.037%) to 3 d.p

b) The result of the 95% confidence interval does not agree with the previous rate of such cancer because the value 0.0224% does not lie within this confidence interval obtained.

Answer:

Step-by-step explanation:

Answer:

x = [tex]\frac{-3+\sqrt{19} }{2}[/tex] or x = [tex]\frac{-3-\sqrt{19} }{2}[/tex]

Step-by-step explanation:

We want to factor this. In order to factor it, we need to use the quadratic formula:

[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] or [tex]x=\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

Here, a = 2, b = 6, and c = -5, so plug these in:

[tex]x=\frac{-6+\sqrt{6^2-4*2*(-5)} }{2*2}=\frac{-6+\sqrt{76} }{4} =\frac{-6+2\sqrt{19} }{4} =\frac{-3+\sqrt{19} }{2}[/tex]

AND

[tex]x=\frac{-6-\sqrt{6^2-4*2*(-5)} }{2*2}=\frac{-6-\sqrt{76} }{4} =\frac{-6-2\sqrt{19} }{4} =\frac{-3-\sqrt{19} }{2}[/tex]

Thus, the answers are x = [tex]\frac{-3+\sqrt{19} }{2}[/tex] or x = [tex]\frac{-3-\sqrt{19} }{2}[/tex].

Hope this helps!
