Step-by-step explanation:

a) unsuitable - the precision should have been about 0.030 kg (about an ounce)

b) unsuitable - the stopwatch should have a precision of 0.001 s

c) just about right, although I wouldn't mind it if its precision is of 0.05 mm

d) unsuitable - color matching requires much finer control so I would go with 1/8 cup precision.

If f(x) = 7 + 4x and g(x)= 7x, what is the value of (f/g)(5)

andrew-mc [135]

The value of $(\frac{f}{g})(5)$ is $\frac{27}{35}$

Explanation:

Given that $f(x)=7+4x$ and $g(x)=7x$

The value of $(\frac{f}{g})(5)$ :

The value of $(\frac{f}{g})(5)$ can be determined by substituting x = 5 in the functions f(x) and g(x) and then dividing the terms, we get, the value of $(\frac{f}{g})(5)$

Thus, we have,

$(\frac{f}{g})(5)=\frac{f(5)}{g(5)}$

Substituting the value of x = 5 in the functions f(x) and g(x), we get,

$(\frac{f}{g})(5)=\frac{7+4(5)}{7(5)}$

Simplifying the terms, we have,

$(\frac{f}{g})(5)=\frac{7+20}{35}$

Adding the terms in numerator, we have,

$(\frac{f}{g})(5)=\frac{27}{35}$

Thus, the value of $(\frac{f}{g})(5)$ is $\frac{27}{35}$

At the school carnival, students are asked to guess the number of marbles in a jar to win a prize. There are 240 marbles in the

Lapatulllka [165]

There is 17% error in the guess.

Step-by-step explanation:

Given,

Number of marbles in jar = Exact value = 240

Closest guess = Approx Value = 280

Percent error = $\frac{|approx-exact}{exact}*100$

Percent error = $\frac{|280-240|}{240}*100\\$

Percent error = $\frac{|40|}{240}*100$

Percent error = $\frac{4000}{240}=16.67\%$

Rounding off to nearest whole percent

Percent error = 17%

There is 17% error in the guess.

26. Which of the following DO NOT illustrates independent events?

AlexFokin [52]

Answer:

C. obtaining an even number when rolling a die

Step-by-step explanation:

Two events are independent when neither depends on the other. That is, the probability that one occurs is not affected by the occurrence, or lack of occurrence, of the other event. Their joint probability is the product of their individual probabilities.

Among the answer choices, all describe two independent events except C. Choice C describes one (1) event, so does NOT illustrate independent events.
