The amount of ice cream that can fit into the cone is about 9.24 in³.

Volume is the amount of space occupied by a three dimensional shape and object. The volume of a cone is given by:

Volume (V) = (1/3) * π * radius² * height

From the dimensions of radius = 1.4 in and height = 4.5 in, hence:

V = (1/3) * π * 1.4² * 4.5 = 9.24 in³

The amount of ice cream that can fit into the cone is about 9.24 in³.

Using the volume of the cone, it is found that 9.24 cubic inches of ice cream will fit inside.

The volume of a cone of radius r and height h is given by:

[tex]V = \frac{\pi r^2h}{3}[/tex]

In this problem, the cone has a radius of 1.4 inches and a height of 4.5 inches, hence r = 1.4, h = 4.5, then:

[tex]V = \frac{\pi 1.4^2(4.5)}{3} = 9.24[/tex]

9.24 cubic inches of ice cream will fit inside.

Answer:

Slope intercept form;

y = mx + b

Find the slope first:

y1 - y2          9 - 4             5

______ =  _______ =  ____ = is undefined

x1 - x2           3 - 3             0

so

y = 5/0x

[tex](\stackrel{x_1}{3}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{9}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{9}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{3}}}\implies \cfrac{5}{0}\implies und efined[/tex]

usually there's no hmm slope-intercept form for it per se, the equation will be like the one in the picture below.

Answer:

y = 2/3x + 2

Step-by-step explanation:

Slope intercept form is y=mx+b where m is the slope and b is the y intercept.

Given 2 points you can find the slope using (y-y1)/(x-x1)

m = (-2-4)/(-6-3) = -6/-9 = 2/3

To find b use one of the points and m and plug into the slope intercept form and then solve for b.

y=mx+b

4=2/3(3) + b

4=2 + b

b=2

Now we can write the final equation as : (plug m and b back in)

y = 2/3x + 2

To write in slope-intercept form, we must first find the slope.

  [tex]Slope = \frac{y2-y1}{x2-x1} =\frac{4-(-2)}{3-(-6)} =\frac{6}{9}=\frac{2}{3}[/tex]

Now lets put into the point-slope form which requires the use of any one of the two points given which in this case can be (3,4) and the slope 2/3

 [tex]y - y_{0} =m(x-x_{0} )\\y-4=\frac{2}{3} (x-3)\\[/tex]

Now to put into the slope-intercept form, we must solve for y:

[tex]y - 4 = \frac{2}{3} x -2\\y = \frac{2}{3} x +2[/tex]

[tex]1-P(8.85 < X < 9.15)=0.3173[/tex]

Step-by-step explanation:

We need to first calculate the probability that a unit between the weight of 8.85 and 9.15 ounces is NOT a defect, then subtract it from 1.

It just so happens that 8.85 and 9.15 are both 1 standard deviation from the mean of 9, so by the Empirical Rule, [tex]P(8.85 < X < 9.15)=0.6827[/tex].

Thus, the probability of a unit being a defect is [tex]1-P(8.85 < X < 9.15)=1-0.6827=0.3173[/tex]

Answer:

48

Step-by-step explanation:

remember 1 dozen of something is 12 of that object

so 1 dozen cookies is 12 cookies

two dozen means two times one dozen

or 2-times twelve (because there are twelve of an object in a dozen)

2 times 12 is 24

now you double the recipe that makes 2 dozen cookies

so you have 24 cookies and you multiply that by 2 to double it and you get 48

Complementary angles T and V would add up to 90 degrees

The true statement is sin V = 0.75

The given parameters are:

cos T = 0.75

Angles T and V are complementary angles

The second highlight above means that:

Substitute 0.75 for cos T in cos T = sin V

0.75 = sin V

Rewrite as:

sin V = 0.75

Hence, the true statement is sin V = 0.75

Answer:

(a) 0.0686

(b) 0.9984

(c) 0.0016

Step-by-step explanation:

Given that a machine produces parts that are either defect free (90%), slightly defective (3%), or obviously defective (7%).

Let A, B, and C be the events of defect-free, slightly defective, and the defective parts produced by the machine.

So, from the given data:

P(A)=0.90, P(B)=0.03, and P(C)=0.07.

Let E be the event that the part is disregarded by the inspection machine.

As a part is incorrectly identified as defective and discarded 2% of the time that a defect free part is input.

So, [tex]P\left(\frac{E}{A}\right)=0.02[/tex]

Now, from the conditional probability,

[tex]P\left(\frac{E}{A}\right)=\frac{P(E\cap A)}{P(A)}[/tex]

[tex]\Rightarrow P(E\cap A)=P\left(\frac{E}{A}\right)\times P(A)[/tex]

[tex]\Rightarrow P(E\cap A)=0.02\times 0.90=0.018\cdots(i)[/tex]

This is the probability of disregarding the defect-free parts by inspection machine.

Similarly,

[tex]P\left(\frac{E}{A}\right)=0.40[/tex]

and [tex]\Rightarrow P(E\cap B)=0.40\times 0.03=0.012\cdots(ii)[/tex]

This is the probability of disregarding the partially defective parts by inspection machine.

[tex]P\left(\frac{E}{A}\right)=0.98[/tex]

and [tex]\Rightarrow P(E\cap C)=0.98\times 0.07=0.0686\cdots(iii)[/tex]

This is the probability of disregarding the defective parts by inspection machine.

(a) The total probability that a part is marked as defective and discarded by the automatic inspection machine

[tex]=P(E\cap C)[/tex]

[tex]= 0.0686[/tex] [from equation (iii)]

(b) The total probability that the parts produced get disregarded by the inspection machine,

[tex]P(E)=P(E\cap A)+P(E\cap B)+P(E\cap C)[/tex]

[tex]\Rightarrow P(E)=0.018+0.012+0.0686[/tex]

[tex]\Rightarrow P(E)=0.0986[/tex]

So, the total probability that the part produced get shipped

[tex]=1-P(E)=1-0.0986=0.9014[/tex]

The probability that the part is good (either defect free or slightly defective)

[tex]=\left(P(A)-P(E\cap A)\right)+\left(P(B)-P(E\cap B)\right)[/tex]

[tex]=(0.9-0.018)+(0.03-0.012)[/tex]

[tex]=0.9[/tex]

So, the probability that a part is 'good' (either defect free or slightly defective) given that it makes it through the inspection machine and gets shipped

[tex]=\frac{\text{Probabilily that shipped part is 'good'}}{\text{Probability of total shipped parts}}[/tex]

[tex]=\frac{0.9}{0.9014}[/tex]

[tex]=0.9984[/tex]

(c) The probability that the 'bad' (defective} parts get shipped

=1- the probability that the 'good' parts get shipped

=1-0.9984

Answer:

C, 0;-4

Step-by-step explanation:

y=-4 means that no matter what the x value is, the y value will ALWAYS be -4. It does not change based on what x is, and we can tell that just by looking at it because x isn't even in the equation. I've attached an image of that the graph would look like.

The slope of the graph references how many units the y value increases for each increase in the x value. For example, a slope of 1/2 means that each time the x value increases by 2, the y value would increase by 1. But because y's value never changes, the slope is 0. No matter how much the x value changes, the increase in y values will be 0.

Since the y-axis is at where x=0, the y-intercept basically asks, "What is y's value when x is 0?" But like I mentioned before y's value never changes. It's always -4, no matter what the x value is. Therefore, the y-intercept is at -4.
