Step-by-step explanation:

P(black or yellow) = P(black) + P(yellow) − P(black and yellow)

P(black or yellow) = 1/25 + 1/5 − 0

P(black or yellow) = 6/25

Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. Se
sesenic [268]

Answer:

Log_5 12=1.54

Step-by-step explanation:

We are given that

Log_5 12

We have to find the value of given logarithms by using change-base formula

Base-change formula:

log_a b=\frac{Log_x b}{Log_x a}

Where x=New base

Using the formula then, we get

Log_5 12=\frac{log_{10} 12}{log_{10} 5}

Substitute the values log_{10}12=1.079, log_{10}5=0.699

Then,we get

Log_5 12=\frac{1.079}{0.699}

Log_5 12=1.54

Find the value of x. Round the length to the nearest tenth.
STALIN [3.7K]

Answer:

x = 5.13 yards to the nearest tenth

Step-by-step explanation:

The diagram is redrawn and labelled in the attached photo.

It is labelled as triangle ABC. Angle A is determined to be 25 degrees. This is because it is alternate to 25 degrees at the top.

To find x, we will apply trigonometric ratio

Tan # =opposite side / adjacent side

Where # = 25 degrees

Opposite side = x

Adjacent side = 11

Tan 25 = x/11

x = 11tan25

x = 11× 0.4663

x = 5.1293 yards

x = 5.13 yards to the nearest tenth.
