Answer:

105

Step-by-step explanation:

First, in problems like these, you have to find 30% of 150. 30% of 150 is 45. Now, since you want to see how many pies have been sold, you do 150-45, which will give you 105.

Answer:

a) 2(n + 5)

b) 2n + 5

Step-by-step explanation:

Writing an     algebraic expression:

  a) Sum of n and 5 ⇒   n + 5

     Twice sum of n and 5 ⇒   2*(n +5)  = 2*n + 2*5

                                                                = 2n + 10

b) Twice n ⇒ 2*n = n

Sum of twice n and 5 ⇒   2n + 5

Based on the relationship between the temperature and altitude change, the slope is -3.6 and the y-intercept is 59. The equation of the line is y = - 3.6x + 59.

First find the slope. This can be found by the formula:

= (Y₂ - Y₁) / (x₂ - x₁)

Two points on line:

(0, 59) and (7, 33.8)

Slope is:

= (33.8 - 59) / (7 - 0)

= -3.6

The y intercept is the point the line crosses the y axis which is 59.

The formula is:

y = mx + c

Where;

m = slope

c = y intercept

So the equation is:

y = -3.6x + 59

The correct angle measurement DZW = 55°

Note the following parameters

, m∠W = 125° and m∠Z = 55°

The measure of angle <DYZ is given as:

<DYZ = 125 ⁰

The opposite angles of a parallelogram are equal.

This means that, angles W and Y have equal measures

This implies that

<ZWZ = <DYZ

<XWZ=125

The adjacent angle of a parallelogram add up to 180 degrees.

This is to say that

<DXW = 180 - <DYZ

<DXW= 180-125

<DXW= 25

Angles X and Z are equal because they are opposite angles.

This is to say that

<Z = 55

Hence, the  measure of angle DZW is 55⁰

Answer:

Cameron's age=48         Christain's age=54

Step-by-step explanation:

The current total age is 102.

You can do 102-6 as this will give you an idea of Christain's age as it is twice the age of Cameron.

102-6=96

96/2=48

Cameron's age=48

102-48=54

54=Christain's age

B is the answer I thought it was C sorry

Option B is correct

1/2 = 2/4

Answer:

Part A: f(4) = 2

Part B: k = -7

Step-by-step explanation:

f(4) simply means what the y-value of the graph is when x = 4.

The parabola crosses the coordinate (4,2). In other words, when x = 4, the graph equals 2.

Part B asks to solve the equation: f(4) + k = -5

We already know from Part A that f(4) = 2. So simply substitute 2 for f(4):

2 + k = - 5

Substract 2 from both sides:

k = -7

The point estimate is 29.73% and the lower and upper limits are 26.63% and 32.83% respectively.

It is defined as an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

[tex]\rm MOE = Z\times \dfrac{s}{\sqrt{n}}[/tex]

Where   Z is the z-score at the confidence interval

            s is the standard deviation

            n is the number of samples.

Point estimate = 22/74 = 0.2973 = 29.73%

Lower limit = point estimate - MOE  = 29.73 - 3.1 = 26.63%

Upper limit = point estimate + MOE = 29.73 + 3.1 = 32.83%

Thus, the point estimate is 29.73% and the lower and upper limits are 26.63% and 32.83% respectively.
