Follow PEMDAS.

Parenthesis
Exponents
Multiplication & Division
Addition & Subtraction

Alright, do multiplication first, then division. Then, do subtraction then addition.

7-1*0+3/3= \\ 7-0+3/3= \\ 7 - 0 + 1= \\ 7 + 1 = 8 \\ 7-1*0+3/3 =8

Hope this helped!

1 . The lengths of the legs of a right triangle are 25 cm and 60 cm. What is the length of the hypotenuse?
Svetlanka [38]
a^{2}+ b^{2} = c^{2} that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.' 
25^{2}+ 60^{2}= x^{2}
625+3600=x^{2}
4225=x^{2}
Therefore,
\sqrt{4225}=x
65=x
The length of the hypotenuse is B.65 centimetres.

Given a normal population which has a mean of 110 and a standard deviation of 5, find the probability that a random sample of 49
Mrac [35]

Answer:

0.9168

Step-by-step explanation:

From the data given:

Mean = 110

standard deviation = 5

Let consider a random sample n =49 which have a mean between 109 and 112.

The test statistics can be computed as:

Z_1 = \dfrac{x- \bar x}{\dfrac{\sigma}{\sqrt{n}}}

Z_1 = \dfrac{109- 110}{\dfrac{5}{\sqrt{49}}}

Z_1= \dfrac{-1}{\dfrac{5}{7}}

Z_1  = -1.4

Z_2= \dfrac{x- \bar x}{\dfrac{\sigma}{\sqrt{n}}}

Z_2 = \dfrac{112- 110}{\dfrac{5}{\sqrt{49}}}

Z_2 = \dfrac{2}{\dfrac{5}{7}}

Z_2 =2.8

Thus; P(109  <  \overline x  <  112) = P( - 1.4 < Z < 2.8)

= P(Z < 2.8) - P( Z < -1.4)

= 0.9974 - 0.0806

= 0.9168
