Answer:

Step-by-step explanation:

It is assumed the question is about finding the minimum value as the given function has no maximum value, it is + ∞ as the coefficient of x² is positive

The minimum/maximum value of a quadratic function is the vertex, which is at:

For the given function y = x² -10x + 31, the vertex is:

The value of y at this point is:

The point is

The conditional probability P(Cow | 2 legs) is 0.

We have,

To find the conditional probability of selecting a cow given that the animal has 2 legs, we need to determine the number of 2-legged animals and the number of cows with 2 legs.

From the given information, we know that cows have 4 legs.

The probability of selecting a cow with 2 legs is 0, since cows do not have 2 legs.

Thus,

The conditional probability P(Cow | 2 legs) is 0.

Answer:

0.0058

Step-by-step explanation:

Probability is defined as the ratio of the possible outcome to the total outcome. The number of single-digit numbers between 1 and 50 is 9 ( from 1 to 9). As such, the probability of generating a single digit integer is

P(single) = 9/50

The probability that the first 3 integers generated are single-digit numbers

= 9/50 * 9/50 * 9/50

= 0.18 * 0.18 * 0.18

= 0.005832

This may be approximated to 0.0058

Answer:

Each friend will receive 210.5 dollars.

Step-by-step explanation:

Total Amount Tyion has = 4,000 dollars

He wants to share evenly with 19 friends.

We need to find How much would amount each friend will receive.

We can found it by using formula:

Amount each friend received = Total Amount / Number of friends

Putting values in the formula and finding results:

Amount each friend received = 4000/19

Amount each friend received = 210.5 dollars

So, each friend will receive 210.5 dollars.

The value that would result in a system of equations with infinitely many solutions is -10

The system of equations is given as:

y = 2x – 5

2y – 4x =

Complete the blank using h.

So, we have:

2y – 4x = h

Make y the subject

2y = 4x + h

Divide through by 2

y = 2x + h/2

By comparing y = 2x + h/2 and y = 2x – 5, we have:

h/2 = -5

Multiply by 2

h = -10

Hence, the value is -10

This sampling technique is called cluster

Step-by-step explanation:

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this question:

The population is divided into groups(by stores), and all elements of the groups(all customers at the stores are sampled), which is the characteristic of a cluster sampling.

Answer

C. x=2

Step-by-step explanation:

This is due to 2(2) = 4

then 3^4=81

81*4=324

The solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.

An exponential function is a mathematical function of the following form:

[tex]f(x) = a^{x}[/tex]. where x is a variable, and a is a constant called the base of the function.

Given exponential equation

[tex]324=4(3)^{2x}[/tex]

[tex]4(3)^{2x}=324[/tex]

[tex]3^{2x} =\frac{324}{4}[/tex]

[tex]3^{2x}=81[/tex]

[tex]3^{2x}=3^{4}[/tex]

When bases are equal, power should be equal.

2x = 4

x = 2

Hence, the solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.

Option C is correct.

Step-by-step explanation:

Answer:

This line intersects the y-axis at [tex]y = 14[/tex]

Step-by-step explanation:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(point where the line intersects the y-axis).

To find the slope, we take two points, and the slope is given by the change in y divided by the change in x.

In this question:

Points (-2,6) and (-4,-2). So

Change in y: -2 - 6 = -8

Change in x: -4 -(-2) = -4 + 2 = -2

Slope: [tex]m = \frac{-8}{-2} = 4[/tex]

So [tex]y = 4x + b[/tex]

Now, we take a point, and find b.

Point (-2,6), which means that when [tex]x = -2, y = 6[/tex]. So

[tex]y = 4x + b[/tex]

[tex]6 = 4(-2) + b[/tex]

[tex]b = 14[/tex]

So this line intersects the y-axis at [tex]y = 14[/tex]

Answer: See explanation

Step-by-step explanation:.

From the question, the equation to illustrate the above question will be:

4(x + 89) = 1952

We can then solve further to get the value of x which will be:

4x + 356 = 1952

4x = 1952 - 356

4x = 1596

x = 1596/4

x = 399

Answer:

Step-by-step explanation:

Since the trapezoid is isosceles, the angles J and M are supplementary and angles M and L are congruent, therefore:

∠M = ∠L = 25*6 - 14° = 150° - 14° = 136°

Answer:

From the given figure we can see that :---

JK||ML, JK=ML and JM=KL

Therefore,

angle J+ angle L = 180°

[tex](7x + 2) + (25x - 14) = 180 \\ 32x - 12 = 180 \\ 32x = 192 \\ \boxed{x = 6}[/tex]

Now, we know that, angle M = angle L

Hence,

[tex]25x - 14 \\ =( 25 \times 6) - 14 \\ =150 - 14 \\ = \boxed{136}[/tex]
