No

Step-by-step explanation:

There are two black 10’s

Answer:

a ) π/2, 4π/3, 3π/2. 5π/3.

Step-by-step explanation:

2 sin t cos t + √3 cos t = 0

cos t ( 2 sin t + √3 ) = 0

Therefore:

cos t = 0,   t 1 = π/2,  t 2 = 3 π/2

or:

2 sin t + √3 = 0

2 sin t = - √3

sin t = - √3 / 2

t 3 = 4 π/3,  t 4 = 5 π/3

Answer:

x = - 5 ; x = 3/2

Step-by-step explanation:

Start by subtracting 15 from both sides to get to an equation in standard form:  a x^2 + b x + c= 0  so we can use the quadratic formula to solve for "x".

2 x^2 + 7x - 15 = 0

Then:

[tex]x=\frac{-7+/-\sqrt{49-4(2)(-15)} }{4} \\x=\frac{-7+/-\sqrt{169} }{4}\\x=\frac{-7+/-13}{4}\\x =-5\\or\\x=3/2[/tex]

Answer:

30

Step-by-step explanation:

4t^2-6 when t is 3

Since we know t=3, we can substitute that in

4(3^2) - 6

Simplify.

3^2 = 9

= 4(9) - 6

= 36 - 6

= 30

Answer:

Step-by-step explanation:

You did the number 3 right because you multiply 3 x 25 is 75.

All you have to do is find what to multiply by the "x" numbers and find the "y" equal answers.

Hope this helps.

Answer:

2.7

Step-by-step explanation:

To round 2.685 to the nearest tenth consider the hundredths’ value of 2.685, which is 8 and equal or more than 5. Therefore, the tenths value of 2.685 increases by 1 to 7.

Answer:

BAE + ECB + ABC = 180 [ BEING INTERIOR TRIANGLE ANGLES SUM ]

Answer:

180 = Angle ABC + BAE + ECB

180 = Angle ABC + 27 + 21

Angle ABC = 180 -27 -21

Angle ABC = 132

Angle ABC = Angle ADC (opposite angles of a parallelogram are equal).

Angle = 132

 52 times 12 = 624

Step-by-step explanation:

364 divided 7 = 52

52 times 12 = 624

Answer:

b

Step-by-step explanation:

If a, b are real numbers and 7a + i(3a - b) = 14 - 6i, then find the values of a and b. Therefore, the value of a = 2 and the value of b = 12. 3.

The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.

The complex number is the combination of the real part and the imaginary part. Then the complex number is given as a+bi where the value of i is √(-1) and the value of i² is -1.

The equation is given below.

7a + (3a - b)i = 14 - 6i

Compare the real part of the equation, then we have

7a = 14

a = 14 / 7

a = 2

Compare the imaginary part of the equation, then we have

3a - b = - 6

3 x 2 - b = -6

6 - b = - 6

b = 6 + 6

b = 12

The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.

The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.

In the context of linear regression analysis, the residual value represents the difference between the observed value of the dependent variable and the predicted value. The formula for calculating the residual value can be expressed as:

Residual = Observed Value - Predicted Value

To calculate the residual value, you need to have a regression model that predicts the value of the dependent variable based on the independent variable(s). Once you have the predicted value, you subtract it from the corresponding observed value to obtain the residual.

For example, if you have an observed value of 10 and the predicted value from the regression model is 8, the residual would be:

Residual = 10 - 8 = 2

The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.

Complete Question

Although the first quarter of 2002 was quite dismal on Wall Street, mutual funds investing in gold companies rose an average of 35.2%. Assume that the distribution of returns in the first quarter of 2002 for mutual funds specializing in gold companies is fairly symmetrical with a mean of 35.2% and a standard deviation of 20%. If random samples of 16 gold stock funds were selected:

 90% of the sample mean returns are between what two values symmetrically distributed around the mean?

Answer:

The two values symmetrically distributed around the mean  are  

   21.87\%   and  43.17\%

Step-by-step explanation:

From the question we are told that

   The sample size is  [tex]n = 16[/tex]

  The sample  mean is  [tex]\= x = 0.352[/tex]

    The standard deviation is  [tex]\sigma = 0.20[/tex]

Generally the degree of freedom is mathematically represented as

      [tex]df = n -1[/tex]

=>   [tex]df = 16 -1[/tex]

=>   [tex]df = 15[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the t distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] at  a degree of freedom of [tex]df = 15[/tex]  is  

   [tex]t_{\frac{\alpha }{2} , 15 } =  2.13 [/tex]

Generally the margin of error is mathematically represented as  

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

=>    [tex]E = 2.13  *  \frac{ 0.20  }{\sqrt{16} }[/tex]  

=>    [tex]E = 0.1065 [/tex]  

Generally 90% confidence interval is mathematically represented as  

      [tex]0.3252  -0.1065 <  \mu < 0.3252  + 0.1065 [/tex]

=>   [tex]0.2187  <  \mu < 0.4317 [/tex]

converting to percentage

      [tex]0.2187 * 100   <  \mu < 0.4317 * 100  [/tex]

=>    [tex] 21.87\%   <  \mu <  43.17\%  [/tex]  

Hence   the 90% of the sample mean returns are between 21.87\%  and 43.17\%

a3=?

a4=102

an= a0+n*d

a4= 6+ 4*d=102 so 4d= 102-6=96, so d=96/4=24

d=24

a1 = 6+24=30

a2 =30+24=54
