Two sides of the rectangle differ by 3. 5 cm find the dimension of the rectangle if its perimetre is 67cm
Answer:
Step-by-step explanation:
Two sides of the rectangle differ by 3.5 cm means that one side is 3.5 cm more than the other side.
If width = x cm, then length = x + 3.5
Perimeter = 67 m
2*(length +width) = 67
2*(x + 3.5 + x) = 67
2*(2x + 3.5) = 67
2*2x + 2*3.5 = 67
4x + 7 = 67
4x = 67 - 7
4x = 60
x = 60/4
x = 15 cm
Width = 15 cm
Length = 15 + 3.5
= 18.5 cm

Answer:
30°
Step-by-step explanation:
y+30° +4y =180° (angles on a straight line equal 180°)
5y+30° =180°
5y= 180° - 30°
5y = 150°

HELP ITS MAKING ME DO ANOTHER ONE
Answer:
Since we know that each of the three triplets are the same age we can put next to n, 3.
And given that another child is 14 years old we can put that next to the "+" sign.
In total, it would equal 32, so put the 32 after the equal sign.
It should look like this:
3n + 14 = 32
But now they want us to solve for the triplet's ages, so we just solve for n;
3n + 14 = 32
-14 -14
3n = 18
/3 /3
n = 6, the triplet's ages are 6 years old each.
There were 324 adults surveyed. Among the participants, the mean number of hours of sleep each night was 7. 5 and the standard deviation was 1. 6. The margin of error, assuming a 95% confidence level, is approximately. Round to the nearest hundredth.
The margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.
What is the margin of error?The margin of error can be defined as the amount of random sampling error in the results of a survey. It is given by the formula,
[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\frac{\sigma^{2}}{n}}[/tex]
[tex]\text{MOE}[/tex] = margin of error
[tex]\gamma[/tex] = confidence level
[tex]z_{\gamma}[/tex] = quantile
σ = standard deviation
n = sample size
As it is given that the sample size of the survey is 324, while the standard deviation of the survey is 1.6.
We know that the value of the z for 95% confidence interval is 1.96. Therefore, using the formula of the standard of error we can write it as,
[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\dfrac{\sigma^{2}}{n}}\\\\\text{MOE}_{\gamma}=1.96 \times \sqrt{\dfrac{1.6^{2}}{324}}\\\\\text{MOE}_{\gamma}=0.1742[/tex]
Hence, the margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.

A business owner opens one store in town A. The equation p(x) = 10,000(1.075)' represents the anticipated profit aft-
t years. The business owner opens a store in town B six months later and predicts the profit from that store to increas
at the same rate. Assume that the initial profit from the store in town B is the same as the initial profit from the store ir
town A. At any time after both stores have opened, how does the profit from the store in town B compare with the pro
from the store in town A?
a
O 65%
O 96%
104%
154%
Mark this and retium
Answer:
96%
Step-by-step explanation:
he rigth equation to anticipate the profit after t years is p(t) = 10,000 (1.075)^t
So, given that both
store A and store B follow the same equations but t is different for them, you can right: Store A: pA (t) 10,000 (1.075)^t
Store B: pB(t'): 10,000 (1.075)^t'
=> pA(t) / pB(t') = 1.075^t / 1.075^t'
=> pA(t) / pB(t') = 1.075 ^ (t - t')
And t - t' = 0.5 years
=> pA(t) / pB(t') = 1.075 ^ (0.5) = 1.0368
or pB(t') / pA(t) = 1.075^(-0.5) = 0.964
=> pB(t') ≈ 0.96 * pA(t)
This means that the profit of store B is about 96%of the profit of store A at any time after both stores have opened.

1. Weather Forecasting
2. Sales Forecasting
explanation
Weather Forecasting : the individual might question themselves about what the weather is gonna look like the day . is it gonna rain ? should I bring an umbrella ? should i take the car to work just incase it starts raining , or should I walk on foot and enjoy the hot sun?
Many retailers use probability to forecast the possibility of selling a specific amount of products on a given day, week, or month. This allows companies to forecast how much stock they will require in the future. A company, for example, may use a forecast model that claims it has a 90% chance of selling at least 100 items on a given day. To avoid running out of items to sell, keep at least 100 (preferably more) on hand at all times.

The circumference is 26.38 yards
Step-by-step explanation:
The formula for finding the circumference of a circle is 2π(r). 2 times pi times the radius. We see that the radius is 4.2 yards, so we plug 4.2 into the variable labeled "r"
2 (3.14) (4.2) = 26.376

Solve the following system of equations.
Answer:
n= -6, a= 5
Step-by-step explanation:
Label the two equations:
a= -2n -7 -----(1)
-3a +n= -21 -----(2)
Substitute (1) into (2):
-3(-2n -7) +n= -21
Expand:
-3(-2n) -3(-7) +n= -21
6n +21 +n= -21
Simplify, minus 21 on both sides:
7n= -21 -21
7n= -42
Divide both sides by 7:
n= -42 ÷7
n= -6
Substitute n= -6 into (1):
a= -2(-6) -7
a= 12 -7
a= 5

An angle measures 18° less than the measure of its supplementary angle. What is the
measure of each angle?
Answer:

∠A and \angle B∠B are supplementary angles. If m\angle A=(2x+26)^{\circ}∠A=(2x+26)
∘
and m\angle B=(x+25)^{\circ}∠B=(x+25)
∘
, then find the measure of \angle B∠B
we know angles A and B are supplementary, thus their sum is 180°.
[tex]\stackrel{\measuredangle A}{(2x+26)}~~ + ~~\stackrel{\measuredangle B}{(x+25)}~~ = ~~180\implies 3x+51=180\implies 3x=129\\\\\\x=\cfrac{129}{3}\implies x=43~\hspace{10em}\stackrel{\measuredangle B = 43 + 25}{68}[/tex]
The measure of angle m∠B = 112°
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.
Supplementary angles have a sum of 180°
Therefore, we can add the expressions for Angles A and B and set their sum equal to 180.
( 2x+26 ) + ( x+25 ) = 180
Now we can combine like terms and apply the operations to find the value of x:
⇒ ( 2x+26 ) + ( x+25 ) = 180
⇒ 3x + 51 = 180
⇒ 3x = 180 - 51
⇒ 3x = 129
⇒ x = 129/3
⇒ x = 43
Then Angle B will have a measure of x+25 = 43 + 25 = 68°
m∠ B = 112°
The measure of Angle A will be :2x+26 = 2(43) + 26 = 112°
m∠A = 68°
Thus, the measure of angle m∠B = 112°
