Answer:

19/30

Step-by-step explanation:

The probability of an event happening or a event not happening is 30/30

Answer:

(B)25

Step-by-step explanation:

From the given diagram:

\angle ACE$ and \angle ECB are on a straight line, and we know by the Linear Postulate that the sum of angles on a straight line is 180 degrees.

Therefore:

\angle ACE$ + \angle ECB=180^\circ$ (Linear Postulate)\\(2x+2)^\circ+(5x+3)^\circ=180^\circ\\$Collect like terms\\2x+5x+2+3=180\\7x+5=180\\$Subtract 5 from both sides\\7x+5-5=180-5\\7x=175\\$Divide both sides by 7\\7x\div 7=175\div 7\\x=25^\circ

The correct option is B.

Answer:

Difference = 2.25°

Step-by-step explanation:

Here we are given that at depth the Temperature T is inversely proportional to the depth x.

T ∝ \frac{1}{x}

T= 4500 \times \frac{1}{x}

Where 4500 is constant

Now we have to find the difference in the temperature at 1200 mts and 3750 mts

1. x=1200

T= 4500 \times \frac{1}{x}

T= 4500 \times \frac{1}{1200}

T= 3.75

2. x=3750

T= 4500 \times \frac{1}{x}

T= 4500 \times \frac{1}{3750}

T=1.2

Hence Difference is

T = 3.75 -1.20

= 2.25

Therefore The difference of the temperature at 1200 mts and 3750 mts is T=2.25°

Express 2.41 x 10/4 in a standard form.
kakasveta [241]

The number written in standard form is 24100

Step-by-step explanation:

An object is said to be written in scientific notation when it is written in the following form:

m\cdot 10^n

where

m is the coefficient

n is the exponent of the power of ten

The number can be rewritten in standard form by writing the coefficient and then moving to the right (or to the left) the decimal point by n positions if n is positive (or negative).

In this problem, the number is

2.41\cdot 10^4

So we have

m = 2.41

n = 4

Therefore, we have to write 2.41 and then move the decimal point 4 positions to the right: so we get

2.41\cdot 10^4 = 24100
