Answer:

Dependent events depends on earlier events to decide if it is used or not.

An example of a dependent event can be the choice of ice cream. Before the person is asked what ice cream they want, they may have been asked what dessert they want. The event of "asking for a choice of ice cream", is dependent on the person stating that they wanted ice cream in the beginning. If they said anything else, they would not get to that question.

Answer:

(3,-3)

y= -3

x= 3

Step-by-step explanation:

5x+2y=9

2x-3y=15

solve the equation

x=9/5-2/5y

2x-3y=15

substitute the value of x into an equation

2(9/5-2/5y)-3y=15

distribute

18/5-4/5y-3y=15

subtract -4/5 to -3

18/5-19/5y=15

subtract 18/5 from both sides

-19/5=57/5

divide both sides by -19/5

y= -3

substitute the value of y into an equation

x=9/5-2/5(-3)

distribute

x=9/5+6/5

add 9/5 to 6/5

x=3

The correct mathematical sentence to represent the situation where the temperature at 10:00 pm (T), if reduced by 5 degrees, would break the record-low of 26 degrees, is T - 5 < 26, which is Option A.

The mathematical expression that represents the situation where Austin checks the temperature at 10:00 pm, and if it falls by 5 more degrees it will break the record-low temperature for that date, which is 26 degrees. The correct mathematical sentence that expresses this information is:

T - 5 < 26

This is because if the temperature at 10:00 p.m., represented by T, falls by 5 degrees and becomes less (<) than 26 degrees, it would break the record-low temperature.

Therefore, the answer is Option A.

Final answer:

Option C is correct as it uses the present participle 'hearing' in a participial phrase, which acts as an adjective.

To find the probability of selecting a brown marble, sum the total probability for all marble colors, solve for x, and then use the value of x to get the probability for brown which is 1/13.

The question involves calculating the probability of selecting a marble of a certain color from a bag containing marbles of different colors, each with a different probability of being chosen. In this particular problem, we are given that the probabilities of selecting red, green, brown, and yellow marbles are 6x, 2x, x, and 4x, respectively.

Since these are the only colors in the bag, their probabilities must add up to 1 (the total probability), so:

6x + 2x + x + 4x = 1

Summing the multiples of x, we get:

13x = 1

Solving for x gives:

x = 1/13

We can now find the probability of selecting a brown marble, which is just x:

Probability of brown = x = 1/13.

The probability of selecting a brown marble from the bag can be found by dividing the number of brown marbles by the total number of marbles in the bag, which is 1/13.

The probability of selecting a brown marble can be found by dividing the number of brown marbles by the total number of marbles in the bag. Since the bag contains four different colors of marbles, the total number of marbles is 6x + 2x + x + 4x = 13x. The number of brown marbles is x. So, the probability of selecting a brown marble is:

P(Brown) = x / (6x + 2x + x + 4x) = x / 13x = 1/13

Answer:

C= 2M + 10

Step-by-step explanation:

In this equation, we will calculate the total cost. So, we'll start off with "C =" Then, we know tat the charge is $2 per mile so we'll add it and make C = 2M. Then, it states that the flat fee is 10 dollars which makes the equation

C = 2M +10.

Answer:

C = 2M + 10

Step-by-step explanation:

To write this equation, we will use slope-intercept form: y = mx+b

In this problem, C is y and M is x, so: C = mM + b

m is the slope, or the rate of change, and b is the y-intercept.

The y-intercept in this problem is the $10 flat fee.

The rate of change is the additional $2 per mile.

Let's input these values into our equation:

C = 2M + 10

Your Answer is :

Answer:

a=68 degrees

Step-by-step explanation:

using the inscribed angle theorem, you know that arc a=2*34=68 degrees.

The measure of the value of a is 64 degrees

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

We have to find the value of a

The measure of arc opposite to the central angle is twice

1/2a=34 degrees

Apply cross multiplication

a=2×34

=64 degrees

Hence, the measure of the value of a is 64 degrees

a) [tex]X<67.1[/tex]

b) 0.1539

c) 0.1539

d) 0.6922

Step-by-step explanation:

a)

In this problem, the score on the exam is normally distributed with the following parameters:

[tex]\mu=78.1[/tex] (mean)

[tex]\sigma = 10.8[/tex] (standard deviation)

We call X the name of the variable (the score obtained in the exam).

Therefore, the event "a student obtains a score less than 67.1) means that the variable X has a value less than 67.1. Mathematically, this means that we are asking for:

[tex]X<67.1[/tex]

And the probability for this to occur can be written as:

[tex]p(X<67.1)[/tex]

b)

To find the probability of X to be less than 67.1, we have to calculate the area under the standardized normal distribution (so, with mean 0 and standard deviation 1) between [tex]z=-\infty[/tex] and [tex]z=Z[/tex], where Z is the z-score corresponding to X = 67.1 on the s tandardized normal distribution.

The z-score corresponding to 67.1 is:

[tex]Z=\frac{67.1-\mu}{\sigma}=\frac{67.1-78.1}{10.8}=-1.02[/tex]

Therefore, the probability that X < 67.1 is equal to the probability that z < -1.02 on the standardized normal distribution:

[tex]p(X<67.1)=p(z<-1.02)[/tex]

And by looking at the z-score tables, we find that this probability is:

[tex]p(z<-1.02)=0.1539[/tex]

And so,

[tex]p(X<67.1)=0.1539[/tex]

c)

Here we want to find the probability that a randomly chosen score is greater than 89.1, so

[tex]p(X>89.1)[/tex]

First of all, we have to calculate the z-score corresponding to this value of X, which is:

[tex]Z=\frac{89.1-\mu}{\sigma}=\frac{89.1-78.1}{10.8}=1.02[/tex]

Then we notice that the z-score tables give only the area on the left of the values on the left of the mean (0), so we have to use the following symmetry property:

[tex]p(z>1.02) =p(z<-1.02)[/tex]

Because the normal distribution is symmetric.

But from part b) we know that

[tex]p(z<-1.02)=0.1539[/tex]

Therefore:

[tex]p(X>89.1)=p(z>1.02)=0.1539[/tex]

d)

Here we want to find the probability that the randomly chosen score is between 67.1 and 89.1, which can be written as

[tex]p(67.1<X<89.1)[/tex]

Or also as

[tex]p(67.1<X<89.1)=1-p(X<67.1)-p(X>89.1)[/tex]

Since the overall probability under the whole distribution must be 1.

From part b) and c) we know that:

[tex]p(X<67.1)=0.1539[/tex]

[tex]p(X>89.1)=0.1539[/tex]

Therefore, here we find immediately than:

[tex]p(67.1<X<89.1)=1-0.1539-0.1539=0.6922[/tex]

Answer:

? = 24, AB = 8.66 (square root of 75, 5 times the square root of 3)

Step-by-step explanation:

Since the whole length equals 27, we can subtract 3 to get 24. The proportion is a setup for geometric mean. This means cross-multiplying. X x X = X^2, 3 x 24 = 72. Square root both sides to get X by itself. [tex]3\sqrt{8} \\[/tex]. Use Pythagoreans to solve the rest. You are left with the square root of 75, or 5 times the square root of 3.

The volume of the part of silo filled with corn is 3391.2 cubic foot.

Step-by-step explanation:

Diameter of the silo = 12ft.

Radius = 6 ft.

Height = 60ft.

Volume = π(r x r) h

= (3.14) (36) 60

= 6782.4 cubic foot

The corn is 50% filled. So,

Volume of corn filled = (50/100) (6782.4)

= 3391.2 cubic foot

The volume of the part of silo filled with corn is 3391.2 cubic foot.
