Answer:

In exponential form given equation is expressed as $b^x=y$

Step-by-step explanation:

Given equation is $x=log_b\,y$

We use the following logarithmic result,

$a^{log_a\,x}=x$

Consider,

$x=log_b\,y$

Take both to the power of b.

$b^{x}=b^{log_b\,y}$

$b^x=y$

Therefore, In exponential form given equation is expressed as $b^x=y$

Use the given values of n= 93 and p= 0.24 to find the minimum value that is not significantly low, μ- 2σ , and the maximum val

allsm [11]

Answer:

The answer is "Option a".

Step-by-step explanation:

$n= 93 \\\\p= 0.24\\\\\mu=?\\\\ \sigma=?\\\\$

Using the binomial distribution: $\mu = n\times p = 93 \times 0.24 = 22.32\\\\\sigma = \sqrt{n \times p \times (1-p)}=\sqrt{93 \times 0.24 \times (1-0.24)}=4.1186$

In this the maximum value which is significantly low, $\mu-2\sigma$ , and the minimum value which is significantly high, $\mu+2\sigma$ , that is equal to:

$\mu-2\sigma = 22.32 - 2(4.1186) = 14.0828 \approx 14.08\\\\\mu+2\sigma = 22.32 + 2(4.1186) = 30.5572 \approx 30.56$

There are 5 red pens and 10 black pens in a cup. If a person randomly selects 3 of them, what is the probability that they're al

kolbaska11 [484]

Answer:

option a)

0.286

Step-by-step explanation:

Given that,

number of red pens in cup = 5

number of black pens in cup = 10

number of pen randomly selected = 3

There are 5 red pens and 10 black pens. So there are 5 + 10 = 15 pens in all.

probability of having all red pens = (5/15 x 4/14 x 3/13)

= 2/91

probability of having all black pens = (10/15 x 9/14 x 8/13)

= 24/91

probability that all pen are of same colour = 24/91 + 2/91

= 2/7

≈ 0.286

A jar has 15 red marbles,5 blue marbles,10 green marbles.what is the ratio of red marbles to the total number of marbles in simp

Misha Larkins [42]

Answer:

1:2

Step-by-step explanation:

The total number of marbles in the jar can be found by adding all the numbers of marbles given:

15+5+10 = 30

Out of 30 total marbles, 15 are red marbles. We can write the ratio as:

15:30

This ration can be simplified to:

1:2

Tatiana [17]

Answer:

I don't think that there is two same results. sorry I couldn't help

Step-by-step explanation:

for I the answer should be 10 if you replaced each x by 2. f(2) = 3(2) + 4

and for II it will be f-1(4) = 3-1(4) - 4 /5 the answer will be -1.

for III it should be y = 8 or 4
