What number is to 100 as 4 is to 78

vitfil [10]

Hello,

4 is to 78 as x is to 100, we write it as a ratio:

$\frac{4}{78}= \frac{x}{100} \\ \\ x= \frac{100*4}{78} \\ \\ \boxed{x= \frac{200}{39}=5.13}$

Sati [7]

Answer:

0.1306

Step-by-step explanation:

This is a binomial distribution problem

Binomial distribution function is represented by

P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ

n = total number of sample spaces = number of free throws

x = Number of successes required = 6

p = probability of success = 0.60

q = probability of failure = 1 - 0.60 = 0.40

P(X = 6) = ⁷C₆ (0.6)⁶ (0.4)⁷⁻⁶ = 0.1306368 = 0.1306

Hope this Helps!!!

aniked [119]

Answer:

70 is answer

Step-by-step explanation:

Given that a function in x is

$f(x) = 5x^2$

we have to find f'(7)

we know by derivative rule derivative of a function is

$f'(x) = lim_({h-->0}) \frac{f(x+h)-f(x)}{h}$

For finding out at 7 we replace x by 7

$f'(7) = lim_({h-->0}) \frac{f(7+h)-f(7)}{h}$

= $lim\frac{5(7+h)^2-5*7^2}{h} \\= lim \frac{10h*7+h^2}{h} \\= 70+h = 70$

So f'(7) = 70

answer is 70

Airida [17]

Answer:

no question content
(x, y) = (1/2, 4)
(x, y) = (2, 10)

Step-by-step explanation:

1. No link, no question

2. Divide the first equation by 2 and substitute for y using the expression in the second equation.

2x +(4x+2) = 5

6x = 3 . . . . . . . . . subtract 2

x = 3/6 = 1/2 . . . . divide by2

y = 4(1/2) +2 = 4 . . . . substitute into the equation for y

The solution is (x, y) = (1/2, 4).

3. The solution using a graphing calculator is (x, y) = (2, 10). (see attached)
