I need an answer what is 1.03 ÷ (-10.3)=?

1 answer:

5 0

The answer is $- \frac{1}{10}$
To figure this out, convert both numbers to fractions. 1.03 = 1 $\frac{3}{100}$ and (-10.3) = -10 $\frac{3}{10}$ . Now, convert to improper fractions.
1 $\frac{3}{100} = [tex] \frac{103}{100}$
-10 $\frac{3}{10}$ = $- \frac{103}{10}$
Now, divide. Dividing fractions is the same as multiplying by the reciporical. So:
$-\frac{103}{10} \ becomes\ \frac{10}{103}$
$\frac{103}{100} *- \frac{10}{103} = -\frac{1030}{10300} = - \frac{1}{10}$

A six-sided number cube is rolled twice.

Marina CMI [18]

Answer: A and D

Step-by-step explanation:

Dependent events mean that one event depends on the outcome of the previous event.

A) If the first roll is a 3, and we want to sum more than 7 with the second roll, then the possible outcomes 5 and 6. Now if the first roll is 4, then the possible outcomes for the second event will be 4, 5 and 6. So you can see how the outcome space of the second event changes depending on the first event, so the events are dependent.

B) Here we do not have dependence, each event only depends on it's own outcome.

C) Again, both events only depend on it's own outcome, so the events are not dependent.

D) This is similar as the case for A, these events are dependent because is not the same if the outcome of the first event is 3, than if the outcome is 5 (the outcome needed for the second roll changes depending on the outcome of the first event)

E) Same as B and C, the events are independent.

Can someone please help me with b, d, and 9-13? I already drew a number line, thanks in advance! :)

inessss [21]

B)
$\frac{3}{13} = s$
d)
$\frac{5}{4} = s$
9) I'm not really sure how to answer it, but I guess like 2.1, 2.2, 2.5, etc.,

10)
${2}^{2} = 4$
${3}^{2} = 9$
so {5, 6, 7, 8} is the answer

11) for some reason it won't let me insert a picture but put place
$\sqrt{4}$
above 2, and then place
$\sqrt{9}$
above 3, and then place
$\sqrt{7}$
in between 2 and 3, but place it a little closer to three since
$\sqrt{7} = 2.65$
12) place
$\sqrt{5}$
between 2 and three, but closer to two since
$\sqrt{5} = 2.24$
and also
$\sqrt{5} < \sqrt{7}$
and for number 13) the square root of 144 is 12, and the square root of 169 is 13, so any numbers between 12 and 13 will work.

I hope this helped and if not, message me and ill try to explain!
