Answer:

  2x -5

Step-by-step explanation:

Any equivalent expression can be used. It is perhaps easiest just to simplify the given expression.

  1/2(6x -10) -x = 3x -5 -x = 2x -5

Putting 2x-5 on the right will give an equation true for all x.

  1/2(6x -10) = 2x -5

Answer: Segment AB is tangent to the circle

Step-by-step explanation:

3 sides are 16, 20, and 12

If angle a is 90 then ab is tangent

now check using Pythagorean theorem

since 12^2 + 16^2 =20^2, this means angle a is a right angle meaning segment AB is tangent to the circle

Answer:

The common denominator of [tex]y + \frac{y-3}{3}[/tex] is 3

Step-by-step explanation:

Given

The complex fraction

Required

The common denominator

To solve this, we need not consider the whole complex fraction.

We only consider

[tex]y + \frac{y-3}{3}[/tex]

Take LCM

[tex]y + \frac{y-3}{3} = \frac{3y - (y-3)}{3}[/tex]

Single out the denominator, i.e. 3

Hence, the common denominator of [tex]y + \frac{y-3}{3}[/tex] is 3

Answer:

Step-by-step explanation:

there are a total of 16+8+8=32 coins in bag

16 out of 32 are red

player wins by pulling a red coin

assume it is a single pull, the winning probability = 16/32 = 1/2

so it is 50/50 chance n hence a fair game

Step-by-step explanation:

yes it is a fair game because any one don't know what the coin will get, it is based on luck

Answer:

Step-by-step explanation:

From the given information:

The mean of the readings is:[tex]=\dfrac{175+104+164+193+131+189+155+133+151+ 176}{10}[/tex]

[tex]= \dfrac{1571}{10}[/tex]

= 157.1

The standard deviation (SD) can be computed by using the expression:

[tex]SD =\sqrt{ \dfrac{\sum_f(x_i - \bar x)^2}{n-1}}[/tex]

[tex]SD =\sqrt{ \dfrac{(175-157.1)^2+(104-157.1)^2+(164-157.1)^2+...+(176-157.1)^2}{10-1}}[/tex]

Standard deviation = 28.195

∴

FOr the EDTA complexes;

The signal detection limit = (3*SD) + [tex]y_{blanks}[/tex]

= (3*28.195) + 50

= 84.585 + 50

= 134.585

We need to point out that the value of the calibration curve given is too vague and it should be (1.75 x 10^9 M^-1) as oppose to  (1.75 x 10^-9 M^-1)

The concentration of detection limit is:

[tex]=\dfrac{3 \times SD}{slope }[/tex]

[tex]=\dfrac{3 \times 28.195}{1.75 \times 10^{9} \ M^{-1} }[/tex]

[tex]\mathbf{= 4.833\times 10^{-8} \ M}[/tex]

The lower limit of quantification is:

[tex]=\dfrac{10 \times SD}{slope }[/tex]

[tex]=\dfrac{10 \times 28.195}{1.75 \times 10^{9} \ M^{-1} }[/tex]

[tex]\mathbf{= 1.611 \times 10^{-7} \ M}[/tex]

Answer:

3%

Step-by-step explanation:

Cost x sales tax rate =tax

370 x sales tax rate = 11.10

sales tax rate =11.10/370

sales tax rate=.03 or 3%

The sales tax rate is 3% if an item costs $370 before tax and the sales tax is $11.10.

The percentage is defined as a ratio expressed as a fraction of 100.

To determine the sales tax rate, we need to divide the amount of sales tax paid by the cost of the item before tax and then multiply the result by 100% to express it as a percentage.

As per the question, the amount of sales tax paid is $11.10, and the cost of the item before tax is $370. Therefore, the sales tax rate is:

sales tax rate = tax paid / (cost of the item before tax) x 100%

sales tax rate = $11.10 / $370 x 100%

Apply the division operation,

sales tax rate = $0.03 x 100%

Apply the multiplication operation,

sales tax rate = 3%

Therefore, the sales tax rate is 3%.

Based on the equation,the equation which is not an inverse variation is f(x) = kx

f(x) = kx

= k × x

f(x) = 2k/x

= k(2/x)

f(x) = -kx/z

= k(-x/z)

Inverse variation is given by:

y = k(1/x)

Answer:

28.125%

Nearest whole percent: 28%

Step-by-step explanation:

54/192 = .28125

move decimal to the right (two times)

28.125%

Using the percentage concept, it is found that 28% of the patients that are cats were seen by Dr. Fluke.

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

In this problem, 54 out of 192 cats were seen by Dr. Fluke, hence the percentage is given by:

[tex]P = \frac{54}{192} \times 100\% = 28.1\%[/tex]

Rounding to the nearest percent, 28%.

Answer:

Step-by-step explanation:

4.5x40=180

180+150=330

400-330=70

70/34=2.05882352941

(2.05882352941x70)+(5.4x150)+(4.5x180)=1791.11764706

1791.11764706/400=4.47779411765

4.47779411765=4.5

4.5m/s

Answer:

Average speed = 3.9 m /s

Step-by-step explanation:

Total distance = 400m

First 150m = 5.4m/s

[tex]speed = \frac{distance}{time} \\\\time = \frac{distance}{speed} = \frac{150}{5.4} = 27.78 \ s[/tex]

Second part :

S = 4.5m/s for 40s

[tex]Distance = speed \times time = 4.5 \times 40 = 180 \ m[/tex]

Third part :

Remaining distance = 400 - 150 -180 = 70m

Time taken to cover it = 34s

[tex]speed = \frac{distance}{time} = \frac{70}{34} = 2.05 \[/tex]

Speed = 2.05m/s

Find average speed

        [tex]Average\ speed = \frac{total \ distance }{total \ time \ taken } \\\\Average \ speed = \frac{400}{101.78} = 3.93 \ mps[/tex]

Round to 1 dp => average speed = 3.9m /s

Answer:

Type II error occurred

Step-by-step explanation:

It is given that a new shampoo is being tested to determine whether the hair grows faster by using this shampoo.

It is known that hair grow at 0.5 inches per month at average.

The hypothesis are,

Null hypothesis, [tex]$H_0: \mu=0.5$[/tex]

Alternate hypothesis, [tex]$H_1: \mu>0.5$[/tex]

But it is known that :

Type [tex]$I$[/tex] error occurs when rejecting the null hypothesis when the null hypothesis is true actually.

Type [tex]$II$[/tex] error occurs [tex]\text{when we fail reject the null hypothesis}[/tex] when the null hypothesis is actually false.

Now here since the null hypothesis is not been rejected, type  [tex]$II$[/tex] error had occurred.

Answer:

a)[tex]S=2.57[/tex]

b)[tex]H=203.2yard[/tex]

c)[tex]X=121.79yards[/tex]

Step-by-step explanation:

From the question we are told that:

Angle [tex]\theta=1.2=68.755^o[/tex]

a)

Generally the equation for Slope is mathematically given by

 [tex]S=tan \theta[/tex]

 [tex]S=tan 68.755[/tex]

 [tex]S=2.57[/tex]

b)

Given the right Angle triangle with horizontal distance [tex]x=85yard[/tex]

Generally the equation for Height traveled is mathematically given by

 [tex]H=tan\theta*x[/tex]

 [tex]H=2.57*85[/tex]

 [tex]H=218.45[/tex]

 [tex]H=203.2yard[/tex]

c)

Generally the equation for Horizontal Distance traveled at 313 height traveled is mathematically given by

[tex]X=\frac{313}{tan65.75}[/tex]

[tex]X=\frac{313}{2.57}[/tex]

[tex]X=121.79yards[/tex]

Using the projectile principle, the slope of the rockets path, height above the ground and the distance traveled at a height of 313 yards would be 2.57, 218.63, 121.69 respectively.

Given the Parameters :

Converting to degree :

A.)

The slope of the rocket's path :

Slope = tan(68.755) = 2.57

B.)

Horizontal distance, = distance along the x-axis = 85 yards

Vertical distance = height = distance along y-axis, y

y = slope × x

y = tan(68.755) × 85

y = 218.63 yards

C.)

Vertical distance, y = 313 yards

From :

[tex] y = x tan\theta [/tex]

[tex] x = \frac{y}{tan\theta} [/tex]

[tex] x = \frac{313}{tan(68.755°)} [/tex]

x = 121.69 yards
