Answer:

x < - 4/5

Step-by-step explanation:

Given the inequality:

4x +4< 9x +8

Collect like terms :

4x - 9x < 8 - 4

-5x < 4

Divide both sides by - 5

-5x / - 5 < 4 / - 5

x < - 4/5

Answer:

(7,5)

Step-by-step explanation:

{2x + 4y = 34

{4y = 27 - x

2x + 27 - x = 34

x=7

4y = 27 - 7

y = 5 so the answer is ( 7,5)

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.

Answer:

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.

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

m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.

If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.

A. 1

B. 154

C. 77

D. 26

Answer: B. m∠K = 154

Step-by-step explanation: Isosceles trapezoid is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.

Related to internal angles, angles of the base are equal and opposite angles are supplementary.

In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:

18x + 8 = 11x + 15

7x = 7

x = 1

Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:

m∠J = 18(1) + 8

m∠J = 26

m∠K + m∠J = 180

m∠K + 26 = 180

m∠K = 154

The angle m∠K is 154°

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.

Time= 5hours

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]

Answer:

The value of x = 11

Step-by-step explanation:

Given

Determining the value of x

As B is between A and C, so

[tex]{\displaystyle {\overline {AB}[/tex] ≅ [tex]{\displaystyle {\overline {BC}[/tex]

as

so

x + 5 = 2(x-3)

x+5 = 2x-6

2x-x = 5+6

x = 11

Therefore, the value of x = 11

Answer:

Example:

X = the first point, so say the point was 2, and the equation for y was, Y=2x +1, you would do 2x2=4 and then 4+1+5 so, for point y it would be, Y=5.

I don't know if that makes sense but yeah.

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

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.

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
