Seven-tenths of the product of 5p and 3 in algebraic expression

maw [93]

Answer:

$\frac{7}{10}(5p*3)$

Step-by-step explanation:

we know that

The algebraic expression of seven-tenths is equal to the number 7 divided by ten

$\frac{7}{10}$

The algebraic expression of the product of 5p and 3 is equal to multiply 5p by 3

$(5p*3)$

therefore

The algebraic expression of seven-tenths of the product of 5p and 3 is equal to

$\frac{7}{10}(5p*3)$

Sven Hendriksson finds that one of his productivity measures is related to the number of employees, e, and the production, n, by

muminat

Answer:

n = 3

e = 5

Step-by-step explanation:

10n + 3e = 45

2n + 5e = 31

10n + 3e = 45

10n + 25e = 155

o + 22e = 110

e = 5

to fix 5 into the first equation

10n + 3(5) = 45

10n + 15 = 45

10n = 45 -15

10n = 30

n = 3

Write the equation of a line in slope intercept form that is perpendicular to y = 2x - 5 and contains (-50,10(

Yanka [14]

Answer:

The equation of the line would be y = -1/2x - 15

Step-by-step explanation:

To find the equation, we need to start by looking at the original equation's slope, which is 2. Perpendicular lines have opposite and reciprocal slopes, so the new line will have a slope of -1/2.

Now we use that and the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 10 = -1/2(x + 50)

y - 10 = -1/2x - 25

y = -1/2x - 15

Pavel [41]

Answer:

0.2239

Step-by-step explanation:

Given that you have two hats. In one hat are balls numbered 1 through 15. In the other hat are balls numbered 16 through 25. I first choose a hat, then from that hat, I choose 3 balls, without replacing the balls between selections.

Either I or II hat can be selected.

Prob of selecting any one hat = 0.5

After selecting I hat, selecting 3 balls can be done in 15C3 ways and from II hat it can be done in 10C3 ways.

total no of ways of selecting 3 balls = (10+15)C3 = 2300

Probability required $=\frac{0.5*15C3+0.5*10C3}{2300} \\=\frac{455+60}{2300} \\=0.2239$
