The English measurement system is primarily used by what country? A. Italy
B. England
C. United States
D. Ireland

Answers

Well unfortunately "english" isn't a measurement system, however there are two measurement systems - we call them "imperial" and "metric". This question is most likely reffering to the imperial system, as that is the system used to some extent in England and in its entirety in the United States. All other countries in the world ise the metric system. The imperial system uses miles, feet, inches, degrees farhenheit, pounds and stone, while the metric system uses kilometres, metres, kilograms and degrees celcius. It has absolutely nothing to do with the language that the country speaks, as countries B, C and D all speak English, along with many other countries. The answer to your question would be C, as the United States is the only country that uses the imperial system to its full extent :))

The English measurement system is primarily used by United States.

Hence the correct option is C. United States.

The English measurement system, also known as the Imperial system, is primarily used by the United States (option C) and to a lesser extent by some other countries that have historical ties to the British Empire.

While England (option B) does use the Imperial system, it is most commonly associated with the United States.

Italy (option A) primarily uses the metric system, and Ireland (option D) officially adopted the metric system in the late 19th century, although some remnants of the Imperial system are still in use in everyday life.

Hence the correct option is C. United States.

What value of c makes x^2 +5x+c a perfect square.

Answers

$Perfect\ square:a^2+2ab+b^2=(a+b)^2\n\nx^2+5x+c=x^2+2x\cdot2.5+c\n\nTh\e coclusion:c=2.5^2=6.25\n\nthen\ x^2+5x+6.25=x^2+2x\cdot2.5+2.5^2=(x+2.5)^2$

To find a perfect square, all you need to do is divide the second coefficient by 2 (5 in this case) and then square it. In other words:

5/2=2.52. 5^2=6.25. Thus, x^2+5+6.25, and in factored form, (x+2.5)(x+2.5)

A student randomly draws a card from a standard deck and checks to see if it is his favorite suit. He then returns the card to the deck, shuffles, and repeats the experiment. He performs the experiments 30 times. Can the probability of drawing his favorite suit be found by using the binomial probability formula? Why or why not?Yes. The events are dependent; however, the 5% guideline can be applied to this situation.
No. The trials are fixed, but the probability of success changes for every trial.
No. The probability of success remains the same for every trial, but the trials are not fixed.
Yes. The outcomes can be classified into two categories, the trials are fixed, and the events are independent.

Rebecca sold 11 more magazine subscriptions than Chad.Laura sold 4 more than Rebecca.Laura sold 45 magazine subscriptions.How many magazine subscriptions did Chad sell?

Answers

Since Laura sold 4 more than Rebecca, you subtract 4 from 45 which is 41, and Rebecca sold 11 more than Chad, you subtract 11 from 41 which is 30.
Laura sold 45 magazine.
Rebecca sold 41 magazine.
Chad sold 30 magzine.

$45-4 = 41 \ (Rebecca) \n\ 41-11 = 30 \ (Chad)$

An initial investment of $60.00 increases in value by 15% each year. Which of the following statements are true? Select all that apply.Select answers;
This function can be represented by the quadratic equation f(x)=0.15(x+60)^2
This situation can be represented by the exponential function f(x)=60 x 1.15^x
This function has no x-intercept
After 4 years the value of the investment will be $120.00
After 6 years the value of the investment will be $653.00
After 7.86 years the value of the investment will be 3 times the initial value
After 8 years the value of the investment will be $184.00

Answers

Answer: The function can be represented by the exponential function :

$f(x)=60(1+0.15)^x=60(1.15)^x$

This function has no x-intercept .

After 7.86 years the value of the investment will be 3 times the initial value .

After 8 years the value of the investment will be $184.00.

Step-by-step explanation:

The exponential growth function is given by :-

$f(x)=A(1+r)^x$ , where A is the initial value , r is the rate of growth and x is the time period.

Given: A = $60

r=15%=0.15

Now, the function can be represented by the exponential function :

$f(x)=60(1+0.15)^x=60(1.15)^x$

We know that exponential function has no intercept , thus this function has no intercept.

∴

Now, at x=4

$f(4)=60(1.15)^4\approx104.94$

Now, at x=6

$f(6)=60(1.15)^6=138.78\approx139$

Now, at x=7.86

$f(7.86)=60(1.15)^(7.86)=179.98180=3(60)$

∴ After 7.86 years the value of the investment will be 3 times the initial value

Now, at x=8

$f(8)=60(1.15)^8=183.54\approx184$

The situations can be represented by the exponential function f(x)=60x1.15^x
After 7.86 years the value of the investment will be three times the initial value (If you round to the nearest dollar)
After 8 years the value of the investment will be $184.00 (If you round to the nearest dollar)
