Answer:

Sqrt32 = 4[tex]\sqrt{2}[/tex], Sqrt28 = 2[tex]\sqrt{7}[/tex], Sqrt12 = 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Square root of 32:

First we find the prime factors of the number by making a factor tree.

32 splits into 8 and 4.

8 splits into 4 and 2

4 splits into 2 and 2

4 splits into 2 and 2

This becomes the square root of [tex]2^{2}[/tex] x [tex]2^{2}[/tex] x 2. It will simplify to:

4[tex]\sqrt{2}[/tex]

Square root of 28:

The prime factors of this number are:

2, and 2

This simplifies to 2[tex]\sqrt{7}[/tex]

Square root of 12:

The prime factors of this are:

3, 2, 2

This simplifies to:

2[tex]\sqrt{3}[/tex]

Answer:

They can not be simplified because they are not perfect squares.

Answer:

y is B. 82 degrees (and for extra, x is 54 degrees)

Step-by-step explanation:

The angles shown are complementary, which means they equal 180 degrees. Subtract 73 from 180 to get 107 degrees for the other angle in this set. After that subtract 25 from 107 to get y, which is 82 degrees.

(For x, just subtract 19 from 73 to get 54 degrees.)

Answer:

The minimum number of samples required is  [tex]n = 16641 [/tex]  

Step-by-step explanation:

From the question we are told that

    The variance is  [tex]\sigma^2 = 0.25[/tex]

    The margin of error is [tex]E = 0.01[/tex]

From the question we are told the confidence coefficient is  0.99 , hence the level of significance is    

      [tex]\alpha = (1 - 0.99 ) \%[/tex]

=>   [tex]\alpha = 0.01[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  2.58[/tex]

Generally the standard deviation is

      [tex]\sigma =\sqrt{\sigma^2}[/tex]

=>   [tex]\sigma =\sqrt{0.25}[/tex]

=>   [tex]\sigma =0.5[/tex]

Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2[/tex]

=>      [tex]n = [\frac{2.58 } *  0.5 }{0.01 } ] ^2[/tex]

=>      [tex]n = 16641 [/tex]

Answer:

1/11

Step-by-step explanation:

If there are 11 counters and there's only 1 white one, that makes it to where there's only a 1 in 11 chance of you choosing that one white counter.

Answer:

The line is y=1x+8

Step-by-step explanation:

We can use point-slope form of a line to make an equation. Point-slope form is as follows:

y-y₁=m(x-x₁)

**The variables y₁ and x₁ are where we will plug in our given coordinates and the variable m is your slope.

1. Plug in the given info:

y-10=1(x-2)

2. Distribute the 1:

y-10=1x-2

3. Add 10 to both sides:

y=1x+8

Answer:

32.0 cm

Step-by-step explanation:

volume of a hemisphere = (2/3)πr3

r = cube root (Volume * 3/2 * 1/π )

r = cube root ( 8514 * 3/2 * 1/π)

r = 15.96

in the nearest tenth r = 16.0 cm

D= 2r

D= 2(16)

D= 32cm

Answer: 31.9 cm

Answer:

a) The negative sign indicates that progression is decreasing in time and decreases by 18 percent each month.

b) Antonio is expected to make a profit of 37445.17 in 7 months from now.

Step-by-step explanation:

a) The equation described on statement represents a geometrical progression, which is defined as:

[tex]y = C_{o}\cdot (1+ r)^{x}[/tex] (1)

Where:

[tex]C_{o}[/tex] - Initial amount, measured in monetary units.

[tex]r[/tex] - Rate, dimensionless. (The progression is increasing when [tex]r > 0[/tex], and decreasing when [tex]-1 < r < 0[/tex])

[tex]x[/tex] - Time, measured in months.

[tex]y[/tex] - Profit, measured in monetary units.

Given that [tex]y = 150,210\cdot (0.82)^{x}[/tex], we calculated the rate below:

[tex]1+r = 0.82[/tex]

[tex]r = 0.82-1[/tex]

[tex]r = -0.18[/tex]

The negative sign indicates that progression is decreasing in time and decreases by 18 percent each month.

b) If we know that [tex]x = 7[/tex], then the expected amount for Antonio in 7 months from now is:

[tex]y = 150,210\cdot (0.82)^{7}[/tex]

[tex]y = 37445.17[/tex]

Antonio is expected to make a profit of 37445.17 in 7 months from now.

Answer:

7+4

Step-by-step explanation:

Answer:

7 + 2x

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

x = 4 is the vertex of the function.

This is a negative quadratic equation and the vertex is the zero of the function. We set (x - 4) equal to 0 and solve.

x - 4 = 0

x = 4

Answer:

Step-by-step explanation:

Let total shirts be x.

Then, Striped shirts = 1/9x

Remaining Shirts= 8/9x

Therefore, Printed Shirts = 5/8 × 8/9x

= 5/9x

Remaining Shirts

or

Plain Shirts= x - ( 5/9x + 1/9x )

= 3/9x

Acc. to problem,

Plain Shirts=81

Therefore,

3/9x=81

=> x=81×9/3

=> x=27×9=243

Therefore,

Total Shirts= 243

I hope that helps you

Answer: 54

It’s funny how I asked the same question around 10 minutes ago xD People told me it’s 54 so here you go :D

Answer:

(B) $1470

Step-by-step explanation:

Given that the principal initial amount, p=$1200

Rate of simple interest per year, r=4.5% = 0.045

Time, t=5 years

Interest after 5 years,

I=prt= 1200 x 0.045 x 5 = 270

Total amount = Principal initial amount + Interest

=1200+270=1470

So, the total amount of the student's savings after 5 years is $1470.

Hence, option (B) is correct.

Answer:

x = 4/7

y = 60/7

Step-by-step explanation:

3x + 4y = 36

y = x + 8

Substitute the second equation into the first since it already has the y isolated for you:

3x + 4(x + 8) = 36

3x + 4x + 32 = 36

7x = 4

x = 4/7

Take the answer you got from the equation above and plug that into the second equation:

y = 4/7 + 8

y = 60/7

To check just LS/RS both equations:

3(4/7) + 4(60/7) = 36

12/7 = 240/7 = 36

252/7 = 36

36 = 36

LS = RS

60/7 = 4/7 + 8

60/7 = 60/7

LS = RS

Answer:

[tex]425\geq x[/tex]

425 pounds or less can be added after the student and football player.

Step-by-step explanation:

let x = remaining weight

(note that >/= is greater than or equal to.)

800 - 280 - 95 >/= x

425 >/= x

Answer:

x < -2 and x > 2

Step-by-step explanation:

Given the inequality |3x| < -6

The function inside modulus can take both positive and negative value.

For the positive value;

3x < -6

x < -6/3

x < -2

For the negative value;

-3x < -6

-3x/-3 > -6/-3

x > 2

Hence the solution to the inequality is x < -2 and x > 2
