The value of the 7 in the number 175,983 is Number times the value of the 7 in 58,972.

C and d are complementary. The measure of c is 4x and the measure of d is 26. What is the value of x

const2013 [10]

Answer:

The value of x is 16.

Step-by-step explanation:

We are given the following in the question:

c and d are complementary angles.

Measure of c = $4x$

Measure of d = 26

Since c and d are complementary, we can write from property of complementary:

$c + d = 90$

Putting values, we get,

$4x + 26 =90\\4x = 90-26 = 64\\\\\Rightarrow x = \dfrac{64}{4} = 16$

Thus, value of x is 16.

Evaluate x2/y + x2/z for x = 6, y = -4, and z = -2.<br> -27<br> -9<br> 9<br> 27

Orlov [11]

<h2>Answer:</h2>

The value of the given expression is -27.

<h2>Given: </h2>

$\frac{x^{2}}{y}+\frac{x^{2}}{z}$

<h2>Step-by-step explanation: </h2>

In this problem, we need to solve the given expression in which we need to find the values of the variables. Since, the values of the variables are given, we can substitute the values and solve the equation as numerical calculation.

On substituting the values,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=\frac{(6)^{2}}{-4}+\frac{(6)^{2}}{-2}$

On squaring the values in the numerator,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-\frac{36}{4}-\frac{36}{2}$

On cancelling the numerator and denominator,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-9-18$

On adding,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-27$

Reasoning in a laboratory, the probability a bacterial colony thrives is 70%. The numbers 0 to 6 represent the outcome that a co

Maurinko [17]

Answer:

The probability that exactly half of the colonies will thrive = (1/3) = 0.3333

Step-by-step explanation:

The list of random numbers simulates the out comes of 4 colonies.

Based On the simulation in 6 trails, what is the probability that exactly half of the colonies will thrive?

The probability of an event is given mathematically as the number of elements in the event divided the total number of elements in the sample space.

Noting that the numbers 0 to 6 indicate that a colony thrives and the number 7 to 9 represent that a colony doesn't thrive.

The 6 trials are given as

4285; 3 colonies thrive, 1 doesn't.

6903; 3 colonies thrive, 1 doesn't.

3829; 2 colonies thrive, 2 don't.

7871; 1 colony thrives, 3 don't.

2868; 2 colonies thrive, 2 don't.

5137; 3 colonies thrive, 1 doesn't.

The number of trials where exactly 2 colonies thrive = 2

The total number of trials = 6

The probability that exactly half of the colonies will thrive = (2/6) = (1/3) = 0.3333

Hope this Helps!!!

What is the answer to this question?

Fudgin [204]

Firstly, multiply both sides by S: $XS=9.4K$

Next, divide both sides by X, and <u>your answer will be $S=\frac{9.4K}{X}$ </u>
