Answer: £36

Step-by-step explanation: 10% is a tenth of the whole price (1/10). We would divide 40 by 10 to get 4 (1/10 of 40)- remember you divide by the bottom of the fraction and times by the top. To get the new price, we subtract 4 from 40 to get £36

Answer:

20.7% is the % decrease.

Step-by-step explanation:

 If you are finding the % of decrease then see below.

% Decrease = (Original Cost - New Cost ) ÷ Original Cost  × 100

5.99 - 4.75 = 1.24

1.24 ÷ 5.99 = .2070

.2070 × 100 = 20.7%

The system is inconsistent because the slopes are the same and the lines are different.

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Given the following system of equations:

y = 6x + 2     (1)

y = 6x + 1      (2)

We can see that both equations have the same slope of 6 but have different y intercepts.

Hence the system is inconsistent because the slopes are the same and the lines are different.

HERE YOU GO (THESE ARE THE RESULTS I GOT FROM THE GUY ABOVE ME):

For each 16 unit increase in x, you get a 6 unit increase in y.

So, you can approach this with the idea of slope (change in y over change in x) to have a slope of 6/16 or 3/8.

y = 3/8 x

This checks out with all of those values.

Answer:

The price was dropped around 15%

Step-by-step explanation:

You will pay $3.15 for a item with original price of $3.70 when discounted 15%. In this example, if you buy an item at $3.70 with 15% discount, you will pay 3.70 - 0.555 = 3.15 dollars.

The number of bottles she can fill if, Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles is 6.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

Given:

Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles,

If each bottle holds 0.75 liters,

Calculate the amount of juice left as shown below,

The amount of juice left = 5 - 0.5

The amount of juice left = 4.5 liter,

Calculate the number of bottles as shown below,

The number of bottles = The amount of juice left / juice held by each bottle

The number of bottle = 4.5 / 0.75

The number of bottles = 6

Answer:

174

Step-by-step explanation:

(10)+(24)+10+123+7

=174

Answer:

174

Step-by-step explanation:

5⋅2+4⋅6+10+123+(8)−1

Multiply 5 and 2 to get 10. Multiply 4 and 6 = 24.

10+24+10+123+8−1

Add 10 and 24 =34.

34+10+123+8−1

Add 34 and 10 =44.

44+123+8−1

Add 44 and 123 =167.

167+8−1

Add 167 and 8 =175.

175−1

Subtract 1 from 175 = 174.

Answer:

It is $0.8

Step-by-step explanation:

First find out the value of one baguette.

They just added one more baguette. So the amount left after subtracting them both will be the cost of 1 baguette.

2.10 - 1.45 = 0.65

Now, subtract the 1st cost with the cost of 1 baguette.

1.45 - 0.65 = $0.8

Using the information given, it is found that the 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year is (0.075, 0.081).

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

3156 out of 40467 adults experienced depression, hence:

[tex]n = 40467, \pi = \frac{3156}{40467} = 0.078[/tex]

95% confidence level

So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].  

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.078 - 1.96\sqrt{\frac{0.078(0.922)}{40467}} = 0.075[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.078 + 1.96\sqrt{\frac{0.078(0.922)}{40467}} = 0.081[/tex]

The 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year is (0.075, 0.081).

Answer:

sin 2θ = -24/25

Step-by-step explanation:

see the below formula of sin x  in terms of tan x

by substituting => -4/3   /  ± √(16/9 + 1)

=> -4/3   /  ± √(25/9)

=> -4/3   / ±  5/3

=> ± -4/5

=> ± 4/5

as theta is in second quadrant is in 2nd quadrant sin value is positive

so sin θ = 4/5 and cos θ = -3/5

now sin 2θ = 2 sinθcosθ

= 2 * 4/5 * -3/5

= -24/25

Answer:

D. First, add 32 to both sides, then divide by -16 and flip the sign

Step-by-step explanation:

Taking that the inequality is -16k-32>-48

First you have to get rid of any addition or subtraction, in this case you have to get rid of -32 by adding 32 to each side:

-16k-32+32 > -48 +32

Then you need to divide by -16 and flip the sign because you are dividing by a negative number and if you don't flip the sign the inequality will be false.
