For each ordered pair, determine when weather it’s a solution to 7x -6y=19
Solutions:
(7,5)
(1,-2)
(-5,3)
(-4,0)

Answers

Answer:

Options A and B

Solution:In order to determine whether or not an ordered pair is a solution to an equation, plug in the values of x and y:7x-6y=197(7)-6(5)=1949-30=1919=19We have a true statement. Therefore, the ordered pair is a solution to the equation 7x-6y=19.Let's try the other ordered pairs.7(1)-6(-2)=197+12=1919=19Here's another true statement.Let's check the remaining two options:7(-5)-6(3)=19-35-18=19-53≠19Here we have a false statement.7(-4)-6(0)=19-28-6=19-34≠19Therefore, the ordered pairs that make this equation true are (7,5) and (1,-2)

The probability of obtaining a head when a certain coin is flipped is about 0. 65. Which of the following is closest to the probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times?.

Answers

The probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times is 0.370

How to determine the probability?

The given parameters are:

Sample size, n = 25Probability of success, p = 0.65Number of success, x ≤ 15

The probability is represented using the following binomial formula

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

Using the above formula, we have:

[tex]P(x \le 15) = 0.370[/tex]

Hence, the probability is 0.370

If m and n are whole numbers such that m^n = 121, then find the value of (m-1)^n+1.​

Answers

Because m and n are whole numbers, we only have 3 values for m, and 3 values for n :

[tex]1^{121} ; 11^{11} ;121^{1}[/tex] (or you can say because 121 only have the factors of 1 ; 11 ; 121, those are the only possible values for m and n, then conclude the possible values)

Now, we will substitute them in :

If m = 1 ; n = 121

[tex](1-1)^{121+1}[/tex] = 0

If m = 11 ; n = 11

[tex](11-1)^{11+1}[/tex] = 1000000000000

If m = 121 ; n = 1

[tex](121-1)^{1+1}[/tex] = 14400

Yesterday a car rental agency rented 4 convertibles and 30 other vehicles. Considering this data, how many of the first 68 vehicles rented today should you expect to be convertibles?

100 points and brainliest to answer

Answers

Answer:

8

Step-by-step explanation:

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

Given:

number of convertibles = 4total number of vehicles = 30 + 4 = 34

[tex]\implies \sf P(convertible)=\dfrac{4}{34}=\dfrac{2}{17}[/tex]

To find the expected number of convertibles from the first 68 vehicles:

[tex]\begin{aligned}\implies \sf P(convertible) \times 68 & =\sf\dfrac{2}{17} \times 68\\\\ & = \sf8\end{aligned}[/tex]

Answer:

30 other vehicles + 4 convertibles = 34 cars

34 * 2 = 68

30 * 2 other vehicles + 4 * 2 convertibles = 68 cars

60 other vehicles and 8 convertibles

Step-by-step explanation:

13: Count the number of spaces from A to D or B to C, which is 4.

Then, count the number of spaces from A to B or C to D, which is also 4.

After that, multiply the two numbers. You should now have an answer of 16.

14: You want to find the diameter of the circle, which is 2.

Then, multiply 2 by 3.14, aka pi. You should now have an answer of 6.28.

*15: Count the number of spaces from A to C, which is 6.

Then, count the number of spaces from A to B, which is 3.

After that, square both of the numbers. 6 x 6 = 36 and 3 x 3 = 9.

Now, the final step. Add both numbers together. 36 + 9 = 45.

You should now have an answer of √45.

The function f(x)=log2x is transformed 4 units down and vertically compressed by a factor of 0.2 to become g(x).

Which function represents the transformation g(x)?

The answer is: g(x)=15log2(x)−4

Answers

Using translation concepts, it is found that function g(x) is given by:

[tex]g(x) = \frac{1}{5}\log_{2}{x} - 4[/tex]

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent function is given by:

[tex]f(x) = \log_{2}{x}[/tex]

It was shifted 4 units down, hence:

[tex]g(x) = \log_{2}{x} - 4[/tex]

It was vertically compressed by a factor of 0.2, hence:

[tex]g(x) = \frac{1}{5}\log_{2}{x} - 4[/tex]

Answers

Answer:

because It's rounded to the nearest hundred place

Step-by-step explanation:

Given equation:

[tex] \ln(x ) = - 3[/tex]

recall that,

[tex] \ln(a ) = b \iff {e}^{b} = a[/tex]

remember, In is natural logarithm which is actually nothing but common logarithm with the base euler's number (e) . anyway rewriting lnx=-3 yields:

[tex] \ln( x ) = - 3\\ \iff {e}^{ - 3} = \frac{1}{ {e}^{3} } [/tex]

1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .

Of the 1250 students registered at the local high school, 30% of them did not vote during the student body elections. How many students did not vote?
A) 350
B) 425
C) 365
D) 375

Answers

Answer: D) 375

Step-by-step explanation:

    We will find 30% of 1,250 since 30% did not vote. A percent divided by 100 becomes a decimal.

30% / 100 = 0.3

1,250 * 0.3 = 375

In 1918, warring nations made peace after four years of "The Great War," now referred to as World War I. The United States retreated somewhat from global politics. Instead, the country focused on its own economic and technologic growth. The 1920s were a prosperous time for many Americans. The economy was booming, and many people made a lot of money. The decade is commonly known as the Roaring Twenties. People focused on having fun, spending time at cinemas and jazz clubs. Consumerism was on the rise. For the first time, factories built new products like cars and telephones for a wide market. With newfound wealth, people were able to buy these luxury items. Though the economy was doing well, mostly managers and business owners profited. Workers were not always so lucky. The gap between the rich and the poor grew. Those who still could not afford fancy new consumer products bought on credit. They took out loans on the promise that they would pay back the money they borrowed. Many people also borrowed money to invest in the stock market. They bought shares of businesses in order to make a profit if the company had success. All this borrowing meant that people saved very little and spent money that they ultimately did not have.
