$abx - 5 = 0$

Add 5 to both sides:
$abx = 5$

Divide by ab:
$x = \frac{5}{ab}$

N triangle xyz, m∠z > m∠x m∠y. which must be true about △xyz?

liubo4ka [24]

The choices are the below that can be found elsewhere:

m∠X + m∠Z < 90°

m∠Y > 90°

∠X and∠Y are complementary

m∠X + m∠Y < 90°

Since the given is m<Z > m<X +m<Y and the sum of measure of angles of a triangle is equal 180 degrees so from this result that the last one choice need being true sure so m<X +m<Y < 90°

Which statements accurately describe the function f(x) = 3(16) Superscript three-fourths x? Select three options.

zzz [600]

Answer:

The initial value is 3.

The range is y greater than 0.

The simplified base is 8.

Step-by-step explanation:

The given function is $f(x) = 3(16)^{\frac{3}{4}x }$ ......... (1)

Therefore, the initial value of the function at x = 0 is $f(0) = 3(16)^{0} = 3$

Now, the domain can be any real value, since for all real value of x, y exists.

But, for no value of x the function has value < 0.

Therefore, y greater than 0 is the range of the function f(x).

Now, simplifying the equation (1) we will have

$f(x) = 3(16)^{\frac{3}{4}x } = 3(16^{\frac{3}{4} } )^{x} = 3(8)^{x}$

Therefore, the simplified base is 8. (Answer)

All I need is this answer,please help!!

il63 [147K]

Hello there,

There is a total of 40 animals in that in 10 zebras, 10 lions, 10 elephants, and 10 monkeys.
So the probability of them both being lions is pretty rare. 2/40 so that would give you a 1/20 chance of both crackers being both lions.

I hope this helps!

The equation r = 6t gives the number of albums released, r, by a record label over time in years, t. If you graph this relations

svp [43]

Choices:
(7, 44)
(8, 48)
(9, 52)
(12, 74)
(13, 78)

r = 6t
(7,44) : r = 6(7) = 42 incorrect
(8,48) : r = 6(8) = 48 CORRECT
(9,52) : r = 6(9) = 54 incorrect
(12,74) : r = 6(12) = 72 incorrect
(13,78) : r = 6(13) = 78 CORRECT

The points that lie on the resulting line are (8,48) and (13,78)

In April and May of 2011, the Pew Research Center surveyed cell phone users about voice calls and text messaging. They surveyed

sleet_krkn [62]

Answer:

D. We can be 95% confident that the proportion of all cell phone users who use text messaging is between 73.1% and 76.9%.

Step-by-step explanation:

The interpretation of a confidence interval of level x% means that we are x% sure that the interval contains the true mean of the population.

In this problem, we have that:

The population are all the cell phone users.

The 95% confidence interval is (73.1%, 76.9%).

Which of the following is an appropriate interpretation of the 95% confidence interval?

D. We can be 95% confident that the proportion of all cell phone users who use text messaging is between 73.1% and 76.9%.
