Answer:

64 is the measure of angle A.

Step-by-step explanation:

===================================================================

The triangle is an isosceles triangle, so when you use the supplementary theorem for angle BCA and 116, you get 64. And since the base pairs are equal, angle A is 64.

===================================================================

Answer:

m∠A = 64°

Step-by-step explanation:

If AB = BC , then ∠CAB ≅ ∠ACB

m∠ACB = 180° - 116° = 64° ⇒ m∠A = 64°

Answer:

[21.9, 22.9] in thousands of dollars

Step-by-step explanation:

The formula for Confidence Interval

= Mean ± z score × standard deviation/√n

Mean = $22.4

Standard deviation = $9.3

n = 2128

z score of 98% confidence interval = 2.326

Confidence Interval = 22.4 ± 2.326 × 9.3/√2128

= 22.4 ± 0.469

Confidence Interval =

22.4 - 0.469

= 21.931

≈ 21.9 in thousand of dollars

22.4 + 0.469

= 22.869

≈ 22.9 in thousands of dollars

Hence, the 98% confidence interval =

[21.9, 22.9] in thousands of dollars

Answer:

a

The 95% confidence interval is   [tex]0.5753<  p <0.62474[/tex]  

b

 This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval

c

 The margin of error is   [tex]E =    0.02474 [/tex]  

d

 The confidence interval becomes wider

Step-by-step explanation:

From the question we are told that

   The sample size is  n = 1506

    The sample proportion is  [tex]\^ p = 0.60[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

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

=>   [tex]\alpha = 0.05[/tex]

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

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>   [tex]E =    1.96 * \sqrt{\frac{0.60 (1- 0.60)}{1506} } [/tex]    

=>   [tex]E =    0.02474 [/tex]  

Generally 95% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>   [tex]0.60 - 0.02474 <  p <0.60 + 0.02474[/tex]  

=>   [tex]0.5753<  p <0.62474[/tex]  

This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval

Generally the level of confidence varies directly with the critical value of [tex]\frac{\alpha }{2}[/tex] and this in turn varies directly with the margin of error which when sample proportion is constant it determines the width of the confidence interval so when the level of confidence increases the confidence interval becomes wider

Answer:

x=5

Step-by-step explanation:

I was working on this problem also.

Maybe my version will help, too.

You need to sketch f given the information you have.

f'(x) is approximately a a cubic polynomial which means f will look like a quartic (think W)

f slopes down (negative slope) to x=2 and then slopes down again...this is a horizontal tangent.

f then slopes down to to x=5 where is has a minimum and then slopes up.

♨ Step - by - step explanation

☯ Given angles :

☯ To find :

✎ Set up an equation and solve for x :

Add the like terms. Remember that Only coefficients of like terms can be added or subtracted.

➺ [tex] \sf{3x \degree + 90 \degree = 180 \degree}[/tex]

Move 90° to right hand side and change it's sign

➺ [tex] \sf{3x \degree = 180 \degree - 90 \degree}[/tex]

Subtract 90° from 180°

➺ [tex] \sf{3x \degree = 90 \degree}[/tex]

Divide both sides by 3

➺ [tex] \sf{ \frac{3x \degree}{3} = \frac{90 \degree }{3} }[/tex]

➺ [tex] \boxed{ \sf{x = 30 \degree}}[/tex]

Answer:

50% of 120 is 60

Step-by-step explanation:

So 60 is half of 120, and 60 times 2 is 50 :)

(Brainliest?)

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Let x as that number ,

So :

[tex] \frac{50}{100} x = 60 \\ [/tex]

[tex] \frac{1}{2} x = 60 \\ [/tex]

Multiply sides by 2

[tex]2 \times \frac{1}{2} x = 2 \times 60 \\ [/tex]

[tex]x = 120[/tex]

Thus that number is 120 .

The number of milligrams of fat that one serving has is 8000 milligrams.

Firstly, it should be noted that

1000mg = 1 gram.

Since three servings of ice cream has 24g of fat, therefore, the fa that will be contained in each will be:

= 24/3

= 8g

Therefore, we'll convert 8 grams to milligrams and this will be:

= 8 × 1000

= 8000 milligrams.

Therefore, a serving has 8000 milligrams.

Answer:

Point of intersection of WY and ZX is (3.5, 3.5).

Step-by-step explanation:

Since, diagonals of a parallelogram bisect each other,

Point of intersection of the diagonals will be midpoint of each diagonal.

By this property, midpoint (x, y) of the segment joining W(-2, 6) and Y(9, 1) will be,

[tex]x=\frac{x_1+x_2}{2}[/tex]

x = [tex]\frac{-2+9}{2}[/tex] = 3.5

Similarly, y-coordinate of the midpoint will be,

y = [tex]\frac{y_1+y_2}{2}[/tex]

y = [tex]\frac{6+1}{2}[/tex] = 3.5

Therefore, point of intersection of the diagonals of the given parallelogram will be (3.5, 3.5).
