Answer:

X=125/64

Step-by-step explanation:

x^2+4 x-5=0

x^2+4x=5

4x^3=5

x^3=5/4

x=5^3/4^3

x=125/64

Answer:

<u>Total number in favour:</u>

128 + 96 = 224

<u>Probability:</u>

P(favour, A) = 128/224 = 4/7

<u>Total number in against:</u>

32 + 48 = 80

<u>Probability:</u>

P(against, not B) = 32/80 = 2/5

Solve 2 log3 x + log3 5 =125

zepelin [54]

Answer:

x = √(3^125/ 5)

approx 2.9552445 * 10^29.

Step-by-step explanation:

2 log3 x + log3 5 =125

log3 x^2 + log3 5 = 125

log3 (5x^2) = 125

3^125 = 5x^2

x^2 = 3^125/ 5

x = √(3^125/ 5)

This is a huge number

An approximation of it is 2.9552445 * 10^29.

The average weight of the top 5 fish caught at a fishing tournament was 12.3 pounds. Some of the weights of the fish are shown i

UNO [17]

Answer:

14.6

Step-by-step explanation:

It is given that,

The average weight of the top 5 fish caught at a fishing tournament was 12.3 pounds. From the attached figure, the weight of 5 fish are given. We need to find the weight of Wayne S. fish.

Average = sum of terms/no of terms

Let the weight of Wayne S. is x. So,

Here the sum of terms is x+12.8+12.6+11.8+9.7 and the number of terms is 5.

$12.3=\dfrac{x+12.8+12.6+11.8+9.7}{5}\\\\61.5=x+12.8+12.6+11.8+9.7\\\\61.5=x+46.9\\\\x=14.6$

So, the weight of the heaviest fish is 14.6.
