A local high school has both male and female students.

Mathematics
1 answer:
Kitty [74]2 years ago
8 0

Answer:

a. P(male) = 0.4

b. P(no sport and male) = 0.1

c. Unclear question (isn't it the same as b.?)

Step-by-step explanation:

The data below is what I've worked according to, which isn't very clear from the question so the answers are only correct if this is the correct table of data;

\left[\begin{array}{ccc}&No \ Sports&Sports\\Female&10&32\\Male&7&21\end {array}\right]

a.

P(male) = \frac{7 + 21}{70} \\\\ = \frac{28}{70} \\\\ = \frac{2}{5}

b.

Using the tree diagram in the picture;

P(no \ sport \ and \ male) = \frac{2}{5} * \frac{1}{4} \\\\ = \frac{1}{10}

Step-by-step explanation:

These are the options for the question.

a) Data degradation

b) Data rot

c) Data security

d) Scattered data

From the question, we are informed about how difficult it's to manage data. For example, it is common for customers to move and for companies to go out of business. This case is an example of Data degradation. Data degradation can be regarded as

corruption of computer data, or gradual alterations of data, and this could be as a result of accumulation of failures in storage devices that store the data, this failure can be critical one or non-critical one

Hans deposits $6000 into an account that pays simple interest at a rate of 5% per year. How much interest will he be paid in the
SpyIntel [72]

Answer:

Hans deposits $6000 into an account.

=> Principal P = 6000

Simple interest rate 5% per year.

=> Rate R = 5% = 5/100 = 0.05

The formula to calculate the amount of interest after 4 years:

A = P x R x years = 6000 x (5/100) x 4 = 1200$

Hope this helps!

To factor the expression 3x2 – 9x, Caleb found the GCF as shown.
Burka [1]

Answer:

Caleb’s error was :

instead of selecting the least exponent ,Caleb took the highest exponent.

Step-by-step explanation:

3x² = 3 • x • x

(in this factorization the exponent of 3 is 1 and the exponent of x is 2)

9x = 3 • 3 • x

(in this factorization the exponent of 3 is 2 and the exponent of x is 1)

• The common factors of 3x² and 9x are 3 and x

In order to determine the GCF ,we have to Compare the exponents of the  common factors then take the numbers which have the least exponent value.

• in the factorization of 3x² the exponent of 3 is 1

and in the factorization of 9x the exponent of 3 is 2

The least exponent is 1 Then we take it.

• in the factorization of 3x² the exponent of x is 2

and in the factorization of 9x the exponent of x is 1

The least exponent is 1 Then we take it.

<u><em>Conclusion</em></u>:

GCF(3x² , 9x) = 3¹ × x¹ = 3x
