Divisibility rules for 2, 5, and 10

Mathematics

lisov135 [29]3 years ago
3 0

For any number to be divisible by 2 the last digit in the number has to be an even number or the number 0.

A and B end with an odd number so cannot be divided by 2.

C ends with 0 so can be divided by 2

The answer is C. 940

Gelneren [198K]
There are a total of 10 fishermen as stated in the given. The probability that a chosen fisherman liked salmon is 3/10. Also, the probability that a fisherman liked bass is 2/10. By using the conjunction "or" we add the probabilities of these events to arrive with the answer giving us 5/10 or 1/2. The answer is letter D.

Multiply.
Helen [10]
Okay. When it comes to multiplying decimals, you multiply them just like you would do whole numbers. However, solving them by paper, you would add a decimal point into the answer, depending on how many numbers are behind the decimal point in the numbers being multiplied. In this case, the decimal point will go in front of two numbers, because there are two numbers behind the decimal point in -1.2 and 0.4. Know that the answer will be negative, because there is one negative and one positive number.
Multiply both numbers. -1.2 * 0.4 is -0.48. There. The product is -0.48.

If the estimate of expected population proportion having a desired characteristic based on intuition is 60 percent and the accep
Anika [276]

Answer:

B

Step-by-step explanation:

Our values are:

N = 100,000 (We assume it)

Proportion is p = 0.6

Margin of error (E) = 0.05

confidence-level (cl) = 0.95

Z-value = 1.96

We need to approach through Proportion,

n=\frac{ (z_2 * p *q) + ME_2}{ME_2 + z_2 * p * q / N}

Substituting,

n = \frac{(1.962*0.6*0.4)+0.052}{0.052 + \frac{1.962 * 0.6 * 0.4}{100000}}

n= \frac{(3.841 * 0.24)+0.0025}{0.0025+\frac{3.841*0.24}{100000}}

n =\frac{ 0.9243}{0.002509}

n= 368

Please help<br>mathematics ​

<h3>Given:</h3>
  • Trapezium
<h3>To find:</h3>
  • Length of BC
  • Value of "x"
<h3>Solution:</h3>

We can divide the given shape into a triangle and a rectangle.

We'll have to use Pythagoras Theorem.

\large\boxed{Formula:{a}^{2}={b}^{2}+{c}^{2}}

In this question we have to find the hypotenuse so we'll have to add.

Let's substitute the values according to the formula.

BC= {6}^{2}+{7}^{2}

BC= 85

BC =  \sqrt{ 85}

\boxed{BC=9.22 \: cm}

Now, we can find the value of "x"

  • Adjacent= 7 cm
  • Opposite= 6 cm
  • Hypotenuse= 9.22 cm

We can use any one from SOHCAHTOA.

Here I'm using tan.

\large\boxed{Formula: tan(a)= \frac{opp}{adj}}

Let's substitute the values according to the formula.

tan \: x= \frac{6}{7}

We'll have to use tan inverse.

x= {tan}^{-1}(\frac{6}{7})

\boxed{x=40.6°}
