Answer:

[tex]P(x<4)=0.0994[/tex]

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

[tex]P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}[/tex]

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

[tex]P(x<4) = P(x\leq3) = P(0) + P(1) + P(2) +P(3)[/tex]

Then:

[tex]P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}[/tex]

[tex]P(x\leq3)=0.0994[/tex]

Probabilities are used to determine the chances of an event

The probability that the number of correct answers is fewer than 4 is 0.0994

The given parameters are:

[tex]n = 9[/tex]

[tex]p =0.6[/tex]

The probability is a binomial probability, and it is calculated using:

[tex]P(x) = ^nC_x p^x (1 - p)^{n -x}[/tex]

Fewer than 4 means: x = 0, 1, 2 and 3

So, we have:

[tex]P(x<4) = ^9C_0 \times 0.6^0 \times (1 - 0.6)^{9 -0} +^9C_1 \times 0.6^1 \times(1 - 0.6)^{9 -1} +^9C_2 \times 0.6^2\times (1 - 0.6)^{9 -2} +^9C_3 \times 0.6^3\times (1 - 0.6)^{9 -3}[/tex]

This gives

[tex]P(x<4) = 1 \times 0.6^0 \times (1 - 0.6)^9 + 9 \times 0.6^1 \times(1 - 0.6)^8 +36 \times 0.6^2 \times (1 - 0.6)^7 +84 \times 0.6^3 \times (1 - 0.6)^6[/tex]

Using a calculator,

[tex]P(x<4) = 0.099352576[/tex]

Approximate

[tex]P(x<4) = 0.0994[/tex]

Hence, the probability that the number of correct answers is fewer than 4 is 0.0994

Hopefully this helps.

Step-by-step explanation:

The total amount of sandwiches on the tray is 4+7+6. This makes 17. This will be the denominator of our fraction which we are going to use for the probability.

There are 7 ham sandwiches on the tray, therefore the probability that he will pick a ham sandwich is 7/17.

Brainliest? :)

Final answer:

The probability that Danny picked a ham sandwich is 7/17, since there are 7 ham sandwiches out of a total of 17 sandwiches on the tray.

Explanation:

The question is about calculating the probability that Danny picked a ham sandwich. To determine this, we count the total number of sandwiches and then count the number of ham sandwiches.

Total number of sandwiches = 4 turkey + 7 ham + 6 tuna = 17 sandwiches.

Since there are 7 ham sandwiches, the probability (P) that Danny picks a ham sandwich is calculated by dividing the number of ham sandwiches by the total number of sandwiches.
P(ham sandwich) = Number of ham sandwiches / Total number of sandwiches
P(ham sandwich) = 7 / 17

Therefore, the probability that Danny picked a ham sandwich is 7/17.

See the attached picture:

The graph is attached.

To graph a parabola we need to know the following:

- If the parabola is open upwards or downwards

- They axis intercepts (if they exist)

- The vertex position (point)

We are given the function:

[tex]f(t)=-16t^{2}+64t+4[/tex]

Where,

[tex]a=-16\\b=64\\c=4[/tex]

For this case, the coefficient of the quadratic term (a) is negative, it means that the parabola opens downwards.

Finding the axis interception points:

Making the function equal to 0, we can find the x-axis (t) intercepts, but since the equation is a function of the time, we will only consider the positive values, so:

[tex]f(t)=-16t^{2}+64t+4\\0=-16t^{2}+64t+4\\-16t^{2}+64t+4=0[/tex]

Using the quadratic equation:

[tex]\frac{-b+-\sqrt{b^{2}-4ac } }{2a}=\frac{-64+-\sqrt{64^{2}-4*-16*4} }{2*-16}\\\\\frac{-64+-\sqrt{64^{2}-4*-16*4} }{2*-16}=\frac{-64+-\sqrt{4096+256} }{-32}\\\\\frac{-64+-\sqrt{4096+256} }{-32}=\frac{-64+-(65.96) }{-32}\\\\t1=\frac{-64+(65.96) }{-32}=-0.06\\\\t2=\frac{-64-(65.96) }{-32}=4.0615[/tex]

So, at t=4.0615 the height of the softball will be 0.

Since we will work only with positive values of "x", since we are working with a function of time:

Let's start from "t" equals to 0 to "t" equals to 4.0615.

So, evaluating we have:

[tex]f(0)=-16(0)^{2}+64(0)+4=4\\\\f(1)=-16(1)^{2}+64(1)+4=52\\\\f(2)=-16(2)^{2}+64(2)+4=68\\\\f(3)=-16(3)^{2}+64(3)+4=52\\\\f(4.061)=-16(4.0615)^{2}+64(4.0615)+4=0.0034=0[/tex]

Finally, we can conclude that:

- The softball reach its maximum height at t equals to 2. (68 feet)

- The softball hits the ground at t equals to 4.0615 (0 feet)

- At t equals to 0, the height of the softball is equal to 4 feet.

Part b) What is the slant height of the outside edge?

we have that

The diameter of the base of the cone is 12 in

so

[tex]r=12/2=6\ in[/tex] ----> the radius is half the diameter

[tex]h=8\ in[/tex]

Applying the Pythagoras Theorem find the slant height x

The first alternative is correct

Step-by-step explanation:

We move all the expressions to the left hand side of the inequality then combine like terms using lcm;

Answer:

the first one

Step-by-step explanation:

Express the left side as a single fraction

3 + [tex]\frac{4}{x}[/tex]

= [tex]\frac{3x+4}{x}[/tex], hence

[tex]\frac{3x+4}{x}[/tex] ≥ [tex]\frac{x+2}{x}[/tex]

Subtract [tex]\frac{3x+4}{x}[/tex] from both sides

0 ≥ [tex]\frac{x+2}{x}[/tex] - [tex]\frac{3x+4}{x}[/tex]

0 ≥ [tex]\frac{-2x-2}{x}[/tex]

Multiply both sides by - 1, remembering to reverse the inequality symbol as a consequence

0 ≤ [tex]\frac{2x+2}{x}[/tex], hence

Kelly's estimated monthly payroll tax is $475.94, which is found by adding together all of her weekly taxes and then multiplying by the average number of weeks in a month.

To estimate the amount of payroll tax Kelly pays each month, we first need to find out how much she pays weekly and then multiply it by the number of weeks in a month on average.

Firstly, we add together all of the weekly taxes she pays, which includes federal income tax ($68.45), state income tax ($22.81), and other taxes ($18.75). The sum equals $110.01.

Then, to convert this weekly tax to a monthly estimation, we multiply by an average of 4.33 weeks in a month (since not every month is precisely 4 weeks). Therefore, $110.01 * 4.33 is approximately $475.94.

Therefore, the best estimation for the monthly payroll tax that Kelly pays is $475.94.

Answer:

P =  8.5 x + 3  ft

Step-by-step explanation:

To find the perimeter, we use the formula

P =2(l+w) where l is the length and w is the width

P =2 (1.25x+3 + 3x-1.5)

Combine like terms

P = 2( 4.25x +1.5)

Distribute the 2

P =  8.5 x + 3  ft

The perimeter of the rectangle in terms of x is [tex]\( {\frac{17}{2}x + 3} \)[/tex].

Given the width of the rectangle is (3x - 1.5) feet and the length is  (1.25x + 3) feet, we can substitute these expressions into the perimeter formula.

First, let's express the width and length in terms of xwith rational numbers to avoid dealing with decimals:

 Width [tex]\( w = 3x - \frac{3}{2} \)[/tex]

Length [tex]\( l = \frac{5}{4}x + 3 \)[/tex]

Now, we can calculate the perimeter:

[tex]\( P = 2(l + w) \)\\ \( P = 2 \left( \left( \frac{5}{4}x + 3 \right) + (3x - \frac{3}{2}) \right) \)\\ \( P = 2 \left( \frac{5}{4}x + 3 + 3x - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{5}{4}x + 3x + 3 - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{5}{4}x + \frac{12}{4}x + \frac{6}{2} - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{17}{4}x + \frac{3}{2} \right) \)\\ \( P = 2 \times \frac{17}{4}x + 2 \times \frac{3}{2} \)\\ \( P = \frac{34}{4}x + 3 \)\\ \( P = \frac{17}{2}x + 3 \)[/tex]

perimeter =  [tex]\( {\frac{17}{2}x + 3} \)[/tex].

Step-by-step explanation:

The exact volume email of the cylinder in the image is 324π in³.

This is calculated using the formula for the volume of a cylinder:

Volume = πr²h

where:

π is a mathematical constant with the approximate value of 3.14

r is the radius of the cylinder

h is the height of the cylinder

In the image, the radius of the cylinder is 3 in and the height is 6 in. Therefore, the volume of the cylinder is:

Volume = π(3 in)²(6 in)

Volume = π(9 in²)(6 in)

Volume = 54π in³

However, the image also contains the text 324π in³.

This is the correct volume of the cylinder, as it takes into account the fact that the cylinder is hollow.

Therefore, the exact volume email of the cylinder in the image is 324π in³.
