40 hours in a week

52 weeks in a year

Tom makes $15 / hour

In a year, the

a. annual income = 15*40*52 = 31200

b. Social Security tax = 31200 * 0.062 = 1934.40

Jake's water bottle has a capacity of 1.43 L. What is the bottle's capacity in milliliters?

otez555 [7]

Answer:

1430 milliliters

Step-by-step explanation:

so basically all you have to remember is 1 liter is 1000 milliliters so just convert the 1 into 1000 then remember that any decimals in the tenths or hundreds place act like the hundred for the on thousand. So 1000 plus 400 plus 30 equal 1430 milliliters.

Suppose the force acting on a column that helps to support a building is a normally distributed random variable X with mean valu

Sauron [17]

Answer:

(1) 0.4207

(2) 0.7799

Step-by-step explanation:

Given,

Mean value,

$\mu = 15.0$

Standard deviation,

$\sigma = 1.25$

(1) P(X ≥ 17.5) = 1 - P( X ≤ 17.5)

$= 1- P(\frac{x-\mu}{\sigma} \leq \frac{17.5-\mu}{\sigma})$

$=1-P(z\leq \frac{17.5 - 15}{1.25})$

$=1-P(z\leq \frac{2.5}{1.25})$

$=1-P(z\leq 2)$

$=1- 0.5793$ ( By using z-score table )

= 0.4207

(2) P(14 ≤ X ≤ 18) = P(X ≤ 18) - P(X ≤ 14)

$=P(z\leq \frac{18 - 15}{1.25}) - P(z\leq \frac{14 - 15}{1.25})$

$=P(z\leq \frac{3}{1.25}) - P(z\leq -\frac{1}{1.25})$

$=P(z\leq 2.4) - P(z\leq -0.8)$

= 0.9918 - 0.2119

= 0.7799

Which statement about the following equation is true? 3x2 â€"" 8x 5 = 5x2.

kati45 [8]

The discriminant is greater than 0, so there are two real roots and it can be determined by using nature of roots.

Given that,

Equation; $\rm 3x^2 - 8x + 5 = 5x^2$

We have to determine,

Which statement about the following equation is true?

According to the question,

To determine the true statement about the equation following all the steps given below.

Equation; $\rm 3x^2-8x+5=5x^2$

Simplify the equation for the roots of the equation,

$\rm 3x^2-8x+5=5x^2\\\\\rm5x^2- 3x^2+8x-5=0\\\\ 2x^2+8x-5=0\\\\ 2x^2+8x-5=0\\\\2x^2+8x=5\\\\2x(x+4)=5\\\\Then, \ 2x = 5, \ \ x = \dfrac{5}{2} \\\\And\ \ x+4=5, \ \ x=5-4, \ \ x=1$

The equation has two real roots and x is 1 and 5/2.

Hence, The discriminant is greater than 0, so there are two real roots.
