Answer:

  2^7 × 5^5

Step-by-step explanation:

10 = 2×5, so your product is ...

  5^3 × 2^5 × (2×5)^2

  = 5^3 × 2^5 ×2^2 ×5^2

  = 2^7 × 5^5

_____

If you remember that the exponent tells you how many times the base is a factor of the product, you should have no trouble with this.

  5^3 × 2^5 × 10^2 = (5·5·5)(2·2·2·2·2)(2·5)(2·5) = 2^7 × 5^5

Answer:

The value of [tex]x(y-z)^2[/tex] is -16.

Step-by-step explanation:

We need to evaluate [tex]x(y-z)^2[/tex] for x = -1, y = 5 and let us assume that z = 1

It can be simply done by putting the values of x,y and z in the given expression.

[tex]x(y-z)^2=(-1)(5-1)^2\\\\=-1(4)^2[/tex]

We know that the value of 4² = 16

So,

[tex]x(y-z)^2=16\times -1\\\\=-16[/tex]

So, the value of [tex]x(y-z)^2[/tex] is -16.

Answer:

53/82

Step-by-step explanation:

Answer:

13/41 + 27/82

We reduce to the same denominator.

The common denominator is 82

=(13×2)/(41×2) + 27/82

= 26/82 + 27/82

to calculate the sum of two fractions that have the same denominator, just add the numerators between them .

= 53/82

Answer:

[tex] x = 10 [/tex]

m<CQF = 32°

m<AQE = 32°

Step-by-step explanation:

m<CQB = m<CQA = 90° (right angle)

m<CQB = m<CQF + m<FQB

m<CQF = 3x + 2

m<FQB = 58°

Therefore,

[tex] 90 = 3x + 2 + 58 [/tex]

Solve for x:

[tex] 90 = 3x + 60 [/tex]

[tex] 90 - 60 = 3x + 60 - 60 [/tex]

[tex] 30 = 3x [/tex]

[tex] \frac{30}{3} = \frac{3x}{3} [/tex]

[tex] 10 = x [/tex]

[tex] x = 10 [/tex]

m<CQF = 3x + 2

Plug in the value of x to find m<CQF

m<CQF = 3(10) + 2 = 30 + 2

m<CQF = 32°

m<CQF and m<AQE are vertical opposite angles, therefore, they are congruent.

Thus,

m<AQE = 32°

Answer:

x = 10

m∠CQF = 32

m∠AQE = 58

Answer:

P( 43 ≤ X ≤ 49) = 0.9545

Step-by-step explanation:

We are given mean of 46 and a standard deviation of 3

We want to find the percentage of daily phone calls numbering between 43 and 49. This can be written as;

P( 43 ≤ X ≤ 49)

Using the z-formula, we have;

z = (x - μ)/s

This transforms to;

P((43 - 46)/3)) ≤ Z ≤ ((49 - 46)/3))

This gives;

P(-2) ≤ Z ≤ P(2)

From z - table attached, P(-2) = 0.02275 and P(2) = 0.97725

Thus;

P( 43 ≤ X ≤ 49) = 0.97725 - 0.02275

P( 43 ≤ X ≤ 49) = 0.9545

Answer: C

Step-by-step explanation:

Excluding men under 30 from the selection process of the survey makes it bias because all mean  50 or younger are supposed to be included.

Step-by-step explanation:

One side of a triangle is 9 cm and other side is 37 cm. We need to find what could be the length of the third side of the triangle.

If we add one and other side i.e. 9 cm + 37 cm = 46 cm

If we subtract one and other side i.e. 37 cm - 9 cm = 28 cm

We know that, the length of the third side must be less than the sum of the other two sides and greater than the difference between the other two sides.

Thus, the third side could be between 46 cm and 28 cm.

Hey there!

There aren't any options, but the correct answer would be 2 6/8, which simplifies to 2 3/4.

Let me know if this helps :)

22/8

8 goes into 22 twice:

8 x 2 = 16

22-16 = 6

22/8 = 2 6/8

6/8 can reduce to 3/4

22/8 = 2 3/4

Answer:

[tex]22.805 < \mu < 24.575\\[/tex]

Step-by-step explanation:

Given parameters

Z interval E = (23.305,25.075)

mean xbar = 23.69

number of samples n = 30

Required

we are to find the confidence interval for the Z interval given.

The formula for finding the confidence interval is expressed as shown below;

[tex]\overline x - E < \mu < \overline x + E[/tex] where;

xbar is the mean = 30

E is the margin of error

[tex]E = \frac{U-L}{2}[/tex]

U =  upper limit = 23.305

L = lower limit = 25.075

[tex]E = \frac{25.075-23.305}{2}\\E = \frac{1.77}{2}\\E = 0.885[/tex]

The confidence interval is therefore expressed as [tex]23.69 - 0.885 < \mu < 23.69+ 0.885\\22.805 < \mu < 24.575\\[/tex]

Hence the confidence interval is expressed as [tex]22.805 < \mu < 24.575\\[/tex]

Answer:

Step-by-step explanation:

Probability is defined as the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

probability = n{E}/n{S}

n(E) is the total number of events

n{S} is the total number of sample space.

For a coin that is tossed 3times, the possible outcome are:

S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

The total number of sample space is n(S) = 2³ = 8

n{S} = 8

a) probability of getting two heads.

Events E = {HHH, HHT, HTH, THH}

n(E) = 4

Pr(getting two heads) = 4/8 = 1/2

b) probability of getting one head.

Events E = {HTT, THT, TTH}

n(E) = 3

Pr(getting one head) = 3/8

c) probability of getting at least one head means probability of getting 1 head and more but not less than a head.

Events E = {HHH, HHT, HTH, HTT, THH, THT, TTH}

n(E) = 7

Pr(getting at least one head) = 7/8

d) probability of getting at least two heads means probability of getting 2 head and more but not less than 2 head.

Events E = {HHH, HHT, HTH, THH}

n(E) = 4

Pr(getting at least two head) = 4/8 = 1/2

Calculate

⇒[tex] \sf{2x = - 38}[/tex]

Divide both sides of the equation by 2

⇒[tex] \sf{ \frac{2x}{2} = \frac{ - 38}{2} }[/tex]

Calculate

⇒[tex] \sf{x = - 19}[/tex]

Step-by-step explanation:

Answer:

y + 5 = (-13/4)(x - 3)

Step-by-step explanation:

Going from (-1, 8) to (3, -5), x (the 'run') increases by 4 and y (the 'rise') decreases by 13.  Thus, the slope of the desired line is m = rise / run = -13/4.

The point-slope formula is

y - k = m(x - h), and here m = -13/4, k = -5 and h = 3:

y + 5 = (-13/4)(x - 3)

Step-by-step explanation:

Answer:

26

Step-by-step explanation:

When we find the values of questions like this, we have to remember to use "PEMDAS".

Because multiplication comes before addition, we have to multiply first.

(Since there are two multiplication parts in the question, we start off by the first one.)

When we multiply both parts, we'll get:

[tex](18)+(8)[/tex], which equals to 26.

So, your answer is 26.

Answer:

= (x + 6) (x - 8)

Step-by-step explanation:

x² - 2x - 48

break the expression into groups:

= (x² + 6x) + (-8x - 48)

= x (x + 6) - 8(x + 6)

= (x + 6) (x - 8)

Answer:

9.22

Step-by-step explanation:

The calculation of z is shown below:-

Given that

2x-4y+4z-6w=4 .... (1)

6w-4x+4y-4z=-12 ..... (2)

6w+4x-2y+6z=64 ...... (3)

4z+2w+6y-4x=56 .... (4)

Here we need to decrease the equations with the help of canceling out a few variables.

Now we need to add equations 1 and 2 that is

(2x - 4x) + (-4y + 4y) + (4z - 4z) + (-6w + 6w) = 4 + 12

Now we solve the above equation

-2x + 0 = 16

-2x = 16

x = -8

Now, equation 2 minus 3

6w - 6w + (-4x - 4x) + 4y + 2y + (-4z - 6z) = 12 - 64

-8x + 6y - 10z = -52

Now we will put the value of x

-8(-8) + 6y - 10z = -52

64 + 6y - 10z = -52

6y - 10z  = -52 - 64

6y - 10z = -116

3y - 5z = -58 ... 5

Equation 3 × 1 and equation 4 × 3

6w + 4x - 2y + 6z = 64 ..... (3)

4z + 2w + 6y - 4x = 56 .... (4)

6w + 4x - 2y + 6z = 64

12z + 6w + 18y - 12x = 168

Now we will subtract both equations that are

16x - 20y - 6z = -104

8x - 10y - 3z = -52

8(-8) - 10y - 3z = -52

-64 - 10y - 3z = -52

-10y - 3z = -52 + 64

-10y - 3z = 12 ....... (6)

equating 5 and 6 and solving that is

3y - 5z = -58 ... 5 × 10

-10y - 3z = 12 ....... 6 × 3

30y - 50z = -580

-30y - 9z = 36

we will add both equation

-50z - 9z = -580 + 36

-59z = -544

z = -544 ÷ -59

After solving z value we will get

= 9.22
