1. Subtract 0.207 from 0.61

The correct value of probability of selecting a 2 both times is 1/200.

Let's calculate the correct probability.When randomly selecting an integer from 0 to 39, there is 1 favorable outcome (selecting a 2) out of 40 possible outcomes. Therefore, the probability of selecting a 2 in the first selection is 1/40.

Similarly, when randomly selecting an integer from 0 to 4, there is 1 favorable outcome (selecting a 2) out of 5 possible outcomes. Therefore, the probability of selecting a 2 in the second selection is 1/5.

To find the probability of both events happening (selecting a 2 in both selections), we multiply the individual probabilities:

P(Selecting a 2 both times) = (1/40) * (1/5) = 1/200

Therefore, the probability of selecting a 2 both times is 1/200.We are given two independent events:

Randomly selecting an integer from 0 to 39 (inclusive).

Randomly selecting an integer from 0 to 4 (inclusive).

We want to calculate the probability of selecting a 2 in both selections.

In the first selection, there is only one favorable outcome (selecting a 2)out of 40 possible outcomes (numbers from 0 to 39). Therefore, the probability of selecting a 2 in the first selection is 1/40.

In the second selection, there is again only one favorable outcome (selecting a 2) out of 5 possible outcomes (numbers from 0 to 4). So, the probability of selecting a 2 in the second selection is 1/5.

Since the two events are independent, we can multiply their individual probabilities to find the probability of both events happening.

Probability of selecting a 2 in both selections = (1/40) * (1/5) = 1/200Therefore, the probability of randomly selecting a 2 in both selections is 1/200. This means that out of all possible outcomes, there is a 1 in 200 chance of selecting a 2 in both selections.

Given:

The sides of a triangle are 3 cm, 5 cm, 7 cm.

To find:

The angle classification of the given triangle.

Solution:

Let a,b,c are the three sides of a triangle ABC, where c is the longest side.

1. Triangle ABC is acute, if [tex]c^2<a^2+b^2[/tex].

2. Triangle ABC is acute, if [tex]c^2=a^2+b^2[/tex].

3. Triangle ABC is acute, if [tex]c^2>a^2+b^2[/tex].

The sum of square of two smaller sides is

[tex]3^2+5^2=9+25[/tex]

[tex]3^2+5^2=34[/tex]

In the given triangle 7 cm is the longest sides. So,

[tex]7^2=49[/tex]

It means,

[tex]7^2>3^2+5^2[/tex]

Since [tex]c^2>a^2+b^2[/tex], therefore, the triangle ABC is an acute triangle.

Answer:

A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.

Step-by-step explanation:

Given

[tex]3x - 3y = 1[/tex]

[tex]-2x+ 4y = 2[/tex]

Required

A good first step

A good first step is to eliminate x and this is done as follows:

Multiply [tex]3x - 3y = 1[/tex] by 2 (gotten from coefficient of x in the second equation)

Multiply [tex]-2x+ 4y = 2[/tex] by 3 (gotten from coefficient of x in the first equation)

This gives:

[tex]6x - 6y = 2[/tex]

[tex]-6x + 12y = 6[/tex]

Add both equations

[tex]6x - 6x - 6y + 12y = 2 + 6[/tex]

[tex]6y = 8[/tex]

[tex]y = \frac{4}{3}[/tex]

Hence (a), is true

Answer:

There are no solutions

Step-by-step explanation:

9x+18−5x=2+4x

Step 1: Simplify both sides of the equation.

9x+18−5x=2+4x

9x+18+−5x=2+4x

(9x+−5x)+(18)=4x+2(Combine Like Terms)

4x+18=4x+2

4x+18=4x+2

Step 2: Subtract 4x from both sides.

4x+18−4x=4x+2−4x

18=2

Step 3: Subtract 18 from both sides.

18−18=2−18

0=−16

There aren't any values of x that would make the equation true.

Answer:

This expression can be simplified to 1

Step-by-step explanation:

[tex]\frac{7^{4n + 19}}{7^{3n - 1}\times{7^{n + 20}}}\\\\= \frac{7^{4n + 19}}{7^{3n - 1 + n + 20}}\\\\= \frac{7^{4n + 19}}{7^{(3n + n) + (20 - 1)}}\\\\= \frac{7^{4n + 19}}{7^{4n + 19}}\\\\= 1[/tex]

Multiply the numerator and denominator by 7×2 = 14 to eliminate the denominators of those fractions:

[tex]\dfrac{\dfrac37}{\dfrac{7\sqrt{10}}2}\times\dfrac{14}{14}=\dfrac{3\times2}{7\sqrt{10}\times7}=\dfrac6{49\sqrt{10}}[/tex]

Rationalize the denominator by multiplying both numerator and denominator by √10:

[tex]\dfrac6{49\sqrt{10}}\times\dfrac{\sqrt{10}}{\sqrt{10}}=\dfrac{6\sqrt{10}}{49(\sqrt{10})^2}=\dfrac{6\sqrt{10}}{49\times10}=\dfrac{6\sqrt{10}}{490}[/tex]

Lastly, cancel the common factor of 2 in both the numerator and denominator (which comes from 6 = 2×3 and 490 = 2×245):

[tex]\dfrac{6\sqrt{10}}{490}=\dfrac{3\sqrt{10}}{245}}[/tex]

Answer:

The period of function h is half the period of the parent function

vertically shifted up 4 units

vertically compressed by a factor of -3

Step-by-step explanation:

The steps involved in plotting the graph  [tex]h = 3cos 2x +4[/tex] were thoroughly discussed.

Given function is:

[tex]h(x) = -3cos(2x-\pi )+4\\[/tex]

The function is a rule that relates two variables.

As we know that

cos(-α) =cos α

So, [tex]h(x) = -3cos(\pi -2x)+4[/tex]

Again, we know that

cos(π-2x) = -cos 2x

So, [tex]h = 3cos 2x +4[/tex]

So, we have to plot the graph [tex]h = 3cos 2x +4[/tex].

Step1: Plot the graph for cos x

Step2: Plot the graph for cos2x, for this replace each x on the graph of cos x by x/2.

Step3: For 3cos2x, replace the range [-1, 1] by [-3,3].

Step4: For 3cos2x + 4, shift the graph 4 units up.

Find the attached graph to understand better.

Hence, The steps involved in plotting the graph  [tex]h = 3cos 2x +4[/tex] were thoroughly discussed.
