For logarithmic equations,

log

b ( x ) = y

logb(x)=y

is equivalent to b y = x

by=x

such that x > 0

x>0 , b > 0

b>0 , and b ≠ 1

b≠1

.In this case, b = 5

b=5 , x = 25

x=25 , and y 2

y=2 .

b = 5

b=5

x =

x=25

y = 2

y=2

Substitute the values of b

b , x

x , and y

into the equation

b y =

On a Sunday night, there are four people on a bus. The bus has five stops left before it end sits route. Suppose each person wil

allochka39001 [22]

There are two possible outcomes of this experiment either success p or failure q. It has a given number of trials and all trials are independent therefore it is binomial probability distribution.

1- 5 ways

2- 5/16

3- 1/16

4- 1/16

In the question given above n= 5 p =1/2 q= 1/2 r is the given point.

Part 1:

The number of ways in which different people get off the bus can be calculated using combinations since the order is not essential. Therefore

nCr= 5C4= 5 ways

2. Part 2:

The probability that all four people get off the bus on the first stop is given by :

P (x= 1)= 5C1 (1/2)^0(1/2)^4= 5(1/2)^4= 5/16

3. Part 3:- The probability that all four people get off the bus on the same stop.

P (x= x)= 5C5 (1/2)^0(1/2)^4= 1(1/2)^4= 1/16

4. Part 4- The probability that exactly three of the four people get off the bus on the same stop.

P (x= x)= 5C5 (1/2)^3(1/2)^1= 1(1/2)^4= 1/16

At one time the aircraft is 150 m above the surface, the submarine is 25 m below the surface, and the underwater robotic vehicle

EastWind [94]

Answer:

$175$ meter is difference in height between the submarine and the aircraft

Step-by-step explanation:

The height of aircraft above the surface $= 150$ meter

Depth at which the submarine lies below the surface $= 25$ meter

Depth at which the underwater robotic vehicle below the surface $= 186$ meter

Difference in height between the submarine and aircraft is equal to

$25 +150 = 175$ meter

UNO [17]

Answer:

we reject H₀

Step-by-step explanation: Se annex

The test is one tail-test (greater than)

Using α = 0,05 (critical value ) from z- table we get

z(c) = 1,64

And Test hypothesis is:

H₀ Null hypothesis μ = μ₀

Hₐ Alternate hypothesis μ > μ₀

Which we need to compare with z(s) = 2,19 (from problem statement)

The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region

So base on our drawing we will reject H₀
