Find x 25 7 х I need help

Mathematics
1 answer:
Murljashka [212]3 years ago
8 0

Answer:

24 = x

Step-by-step explanation:

You use Pythagorean theorem. Since the normal equation is a^{2} + b^{2} =c^{2}, you already have the c^{2} and another side which can be a^{2} or b^{2}.

Because you have the hypotenuse and a side , your equation looks like this now: 7^{2} +b^{2} = 25^{2}

and when you solve for be you just subtract 25^{2} -7^{2} to get 24.

Use the zero product property to find the solutions to the equation x^2 + x -30=12
Alla [95]

Answer:

The solutions are x = -7, 6.

Step-by-step explanation:

To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.

x^2 + x - 30 = 12\\x^2 + x -42=0\\(x+7)(x-6) = 0

x+7 = 0

x = -7

and

x-6 = 0

x = 6

The solutions are x = -7, 6.

Anna11 [10]

Complete Question

A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places

Answer:

0.1151

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = $45.20

μ is the population mean = $50

σ is the population standard deviation = $4

We are solving for x < 45.20

Hence:

z = 45.20 - 50/4

z = -1.2

Probability value from Z-Table:

P(x<45.20) = 0.11507

Approximately to 4 decimal places = 0.1151

Therefore, the proportion of wand prices that are lower than the price of the blackthorn wand is 0.1151
