Answer: We are given 3 out of 15, the best is to convert into a percent, [tex]\frac{3}{15}[/tex] is our fraction, now divide the numerator by the denominator 3÷15=.0.20. Now bump it up two digits, 20%. Now 20% of 15 is 3, we need to find 20% of 10, if 20% is 20 from 100, then 2 must be 20% of 10.

And your answer is 2 out of 10 tosses.

Answer: [tex]\frac{20}{3} %[/tex]%

Step-by-step explanation:

Convert 3m to cm:

[tex](3m)(\frac{100cm}{1m} )=300cm[/tex]

Now divide 20cm by 300cm:

20cm/300cm=1/15

Multiply (1/15) by 100% to convert the fraction to a decimal:

(1/15)(100%)=[tex]\frac{20}{3} %[/tex]%

Answer:

The point in which the graph crosses the x-axis is called the x-intercept and the point in which the graph crosses the y-axis is called the y-intercept. The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).

Answer:

176.74 cm^2

Step-by-step explanation:

Area of a circle is πr^2

r= 7.5

π= 3.142

Area=3.142× 7.5^2

= 3.142 × 56.25

= 176.74 cm^2

Hence the area if the circle is 176.74cm^2

Answer:

Positive: (-2,1)

Negative: (-∞,-2) U (1,∞)

Step-by-step explanation:

The graph of the function f(x) is given in the figure. We can see some points like (-2,0), (-1,1), (2,-2), and many others.

Note the second value of each point (the value of y) is positive or negative. When it's positive, the graph is above the x-axis, when it's negative, the graph is below the x-axis. When it's 0, the graph crosses the x-axis.

To find the intervals of x where the function is positive, we only have to look into the zone where the graph is above the x-axis. It can be identified as the interval (-2,1).

Similarly, the function is negative in the interval (-∞,-2) U (1,∞)

The function f(x) is positive in the interval [-2, 1].

The function f(x) is negative the interval (-∞, -2) U (1, ∞).

The positive regions of a function f(x) are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero).

To find the intervals of x where the function is positive,

In the interval [-2, 1] , the function f(x) is positive.

The negative regions of a function f(x) are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).

In the interval (-∞,-2) U (1,∞) , the function f(x) is negative.

y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.

when y = 0, x = -2, 1

Therefore, the function f(x) is positive in the interval [-2, 1] and negative in the interval (-∞,-2) U (1,∞).

39 sweets

Step-by-step explanation:

the sum of the ratio is

1+4+4= 9

to find the number of sweets shared we say

1/9*X=13 sweets

X=9*13

X=117

therefore Gavin and jim will share equal number of sweets

117-13

104 sweets. Jim gets 52 while Gavin gets 52 sweets.

How many more sweets does Gavin get over Stephen?​

52-13

Gavin get 39 more sweets over Stephen. I hope that helps

The line is parallel so it has the same slope as the other line, -4.

Substitute the x and y variables with the given points and find the y-intercept.

(-8, 6)

y = -4x + b

6 = -4(8) + b

6 = -32 + b

6 + 32 = b

38 = b

So the equation is:

y = -4 + 38

The line is parallel so it has the same slope as the other line, -4.

Substitute the x and y variables with the given points and find the y-intercept.

We have given that,

An equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1

(-8, 6)

y=mx+b

Where m is the slope

y = -4x + b

6 = -4(8) + b

6 = -32 + b

6 + 32 = b

38 = b

So the equation is y = -4 + 38.

Answer:

f(x) = (x+5)(x-4)

Step-by-step explanation:

Key skills used in this problem: Quadratic equations, factoring

1) The equation x^2 + x - 20 is factorable (meaning it can be facttored easily)

2) We need to find factors of -20 that add up to 1. This is because our ac (a term times the c term) is -20 and our b term (the coefficient for +x) is 1.

3) The two factors would be 5 and -4.

4) So it would be (x + 5)(x - 4) when factored

Hope you understood and have a nice day!! :D

Answer:

f(x)= (x+5)(x-4)

Step-by-step explanation:

First muliply the coefficient of the xsquared with the constant, in this case 1 × -20 = -20. Then figure out two factors of -20 that equal the coefficient of the stand-alone x when added together. In this case, that coefficient is 1. Factors of -20 that add to 1 are 5 and -4. Now simply take each of those numbers and shove them into parenthesis with an x.

Step-by-step explanation:

2^400=2^(2×200)

2^(2×200) =[2^(2) ]^200

Now, [2^(2) ]^200=4^200

The power  of 2 in 400! is 397.

Let p is the prime number whose power is to be found

Let n is the factorial number then

p in n! = (n /p) + (n/p²) +(n/p³) + .......

until Numerator < Denominator

and after division only the integer part is taken

Therefore to determine the power of 2 in 400!

2 in 400! = (400 /2) + ( 400 /2²) + (400 /2³) +(400 /2⁴) +(400 /2⁵) +(400 /2⁶) +(400 /2⁷) +(400 /2⁸) + above this N < D

2 in 400! = 200 +100 +50+25+12+6+3+1

2 in 400 = 397

Therefore the power  of 2 in 400! is 397.
