Answer:

  (b)  10.5 in

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = 1/3πr²h . . . . . . for radius r and height h

Then the height is ...

  h = 3V/(πr²)

Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...

  h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in

The height of the cone is about 10.5 inches.

Answer:

y=92

z=57

TWO METHODS:

1) z=180-31-92 (small triangle)

2) z=180-60-63 (big triangle)

Step-by-step explanation:

63+29+x=180

x=180-92

x=88

y=180-88

y=92

z=180-31-92

z=57

Step-by-step explanation:

Answer:

16 units²

Step-by-step explanation:

Area of the right triangle = ½ × base × height

base = 8

height = 4

Substitute

Area = ½ × 8 × 4

Area = ½ × 32

Area = 16 units²

Answer:

4 1/2

Step-by-step explanation:

.

Answer:

4 1/2

Step-by-step explanation:

9/2 as a mixed fraction.

= 9 ÷ 2

= 4 which leaves a remainder of 1

▪Take the 4 as the whole number, take the remainder 1 and place it over the denominator which is 2

You then get your answer.

4 1/2

Step-by-step explanation:

Answer:

120

Step-by-step explanation:

Answer:

a) Trials are independent, and there is a fixed number of trials, which means that the binomial probability distribution can be used.

b) 0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking

Step-by-step explanation:

Binomial probability 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.

a)

For each senior, there are only two possible outcomes. Either they disapprove daily pot smoking, or they do not. The seniors are selected at random, which means that the probability of one disapproving daily pot smoking is independent of other seniors, that is, the trials are independent. There is also a fixed number of trials.

b)

70% disapprove of daily pot smoking, according to a report in Parade, which means that [tex]p = 0.7[/tex]

12 seniors means that [tex]n = 12[/tex]

The probability is P(X = 1).

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

[tex]P(X = 1) = C_{12,1}.(0.7)^{1}.(0.3)^{11} = 0.000015[/tex]

0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking

Answer:

Option C, [tex]y = -2x + 7[/tex]  

Step-by-step explanation:

1) Slope-intercept format is represented by the formula [tex]y = mx + b[/tex]. By looking at the options, we can see that all of them follow this format.  

So, first, we can identify which equations have a slope of -2 to narrow down our options. In slope-intercept form, the coefficient of the x-term, or [tex]m[/tex], represents the slope. So, this narrows the answer down to options b and c because they are the only ones that have [tex]m[/tex] as -2.  

2) Next, in order to find which equation is the right answer, we can substitute the x and y values of the given point (4, -1) into both equations, then simplify. Whichever equation results in a true statement must be the answer. Let's try option c first. Substitute 4 for x and -1 for y:

[tex]-1=4(-2)+7\\-1 = -8+7\\-1=-1[/tex]

-1 does equal -1, so this statement is true. Thus, option c must be the answer.

The equation of the straight line will be -

y = -2x + 7

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have an equation of the line that passes through the point (4,-1) and has a slope of -2.

Assume the equation of the line to be -

y = -2x + c

The line passes through the point (4,-1), so we can write -

-1 = -2 x 4 + c

-1 = -8 + c

c = -1 + 8

c = 7

Therefore, the equation of the straight line will be -

y = -2x + 7

Answer:

B

Step-by-step explanation:

Anything times zero is zero, so any whole number can be the second one so long as the first is 0.

The sum doesnt have to equal zero because non zero numbers multiplied by zero still equal zero.

Answer:

Standard deviation = 0.59

Step-by-step explanation:

Given data → 5.6, 5.2, 4.6, 4.9, 5.7, 6.4

Mean of the given data = [tex]\frac{5.6+5.2+4.6+4.9+5.7+6.4}{6}[/tex]

                                       = 5.4

   Data (x)              (x - mean)            (x - mean)²

     5.6             5.6 - 5.4 = 0.2             (0.2)² = 0.04

     5.2             5.2 - 5.4 = -0.2            (-0.2)² = 0.04

     4.6             4.6 - 5.4 = -0.8            (-0.8)² = 0.64

     4.9             4.9 - 5.4 = -0.5            (-0.5)² = 0.25

     5.7             5.7 - 5.4 = -0.3             (-0.3)² = 0.09

     6.4             6.4 - 5.4 = 1                  (1)² = 1

  N = 6                                                [tex]\sum (x-mean)^2[/tex] = 2.06

Since, Standard deviation = [tex]\sqrt{\frac{\sum (x-mean)^2}{N}}[/tex]

                                           = [tex]\sqrt{\frac{2.06}{6} }[/tex]

                                           = 0.5859

                                           ≈ 0.59
