Can someone pleaseeee help me with this!!

Answer:

11.8 ;

0.1036360

Step-by-step explanation:

Mean births per day, μ = number of births per year / number of days in a year ;

4310 / 365 = 11. 8 births per day

From poisson distribution :

P(x) = (μ^x * e^-μ) ÷ x!

P(x = 13) = (11.8^13 * e^-11.8) ÷ 13!

P(x = 13) = 6.453438E8 / 13!

P(x = 13) = 0.1036360

Answer:

0.8

Step-by-step explanation:

I Dont know 3, 4, 5 so I am going to just use the normal formula

a^2 + b^2 = c^2

0.6^2 + b^2 = 1^2

0.36 + b^2 = 1

b^2 = 0.64

b= 0.8

Answer: 81 miles

Step-by-step explanation:

if 2 inches = 54miles then 1 inch is 27 miles because 54/2=27

so 3 inches means 3(27)=81 miles from yuma to sentinel

Answer:

Michael starts a website for people in his town to share news and photos.  Before launching the website, he has his friends and family sign up.  Then, he uses the equation shown below to estimate the number of user, y, who will have signed up x weeks after he officially launches the website.

y = 82(1.045)x

What is the rate of growth Michael expects each week after launching the website?

The answer will be %0.045

Step-by-step explanation:

The rate of growth Michael expects each week after launching the website is 4.5%.

Given that,

Based on the above information, the calculation is as follows:

Since 1.045 is given so this means 4.5% is the growth rate.

Therefore we can conclude that the rate of growth Michael expects each week after launching the website is 4.5%.

Answer:

Total=600+70(x)

The average cost of the phone is C(x) = (600 + 70x)/x.

In order to calculate average, divide the total sum of the data to the total number of data. An average is a standard number for a given data whose value can both be more or less than it.

Given that,

The fixed price of the cellphone is $600.

And, the monthly plan is $70.

Now, the cost of the phone increases with the number of months and the average cost is the total cost divided by the number of months.

As per the question the average cost can be written as,

C(x) = (600 + 70x)/x

Where x is the number of months.

Hence, the average cost of the given phone can be written in terms of the function of month as C(x) = (600 + 70x)/x.

Answer:

128

Step-by-step explanation:

Hey There!

So the rule about interior angles of a trapezoid

is that the angles that lie on the segments that are not parallel are supplements

so essentially what I'm saying is that angle R and angle U are supplementary angles so to find x we do

180=15x+8+7x-4

step 1 combine like terms

15+7=22

8-4=4

now we have

180=22x+4

step 2 subtract 4 from each side

180-4=176

now we have

176=22x

step 3 divide each side by 22

176/22=8

so x=8

now we plug in 8 to 15x+8

8x15=120

120+8=128

so we can conclude that angle R = 128

Answer:

2.625

Step-by-step explanation:

Last week Thomas ran 5 1/4 miles

This week he plans to run 1/2 miles as far

Therefore the number of miles he plans to run cann be calculated as follows

= 5 1/4 × 1/2

= 21/4 × 1/2

= 21/8

= 2.625

Hence Thomas plans to run 2.625 miles

Answer:

132 square units

Step-by-step explanation:

We are to find the surface area of a square pyramid.

From the diagram above, we are given:

Slant height = 6 units

Base = 8 units

The formula is given as:

= 2bs + b²

= 2 × 8 × 6 + 6²

= 96 + 36

= 132 square units

Answer:

[tex]EF=4\sqrt{3}[/tex]

Step-by-step explanation:

In rectangle ABCD, AB = 6, BC = 8, and DE = DF.

ΔDEF is one-fourth the area of rectangle ABCD.

We want to determine the length of EF.

First, we can find the area of the rectangle. Since the length AB and width BC measures 6 by 8, the area of the rectangle is:

[tex]A_{\text{rect}}=8(6)=48\text{ cm}^2[/tex]

The area of the triangle is 1/4 of this. Therefore:

[tex]\displaystyle A_{\text{tri}}=\frac{1}{4}(48)=12\text{ cm}^2[/tex]

The area of a triangle is half of its base times its height. The base and height of the triangle is DE and DF. Therefore:

[tex]\displaystyle 12=\frac{1}{2}(DE)(DF)[/tex]

Since DE = DF:

[tex]24=DF^2[/tex]

Thus:

[tex]DF=\sqrt{24}=\sqrt{4\cdot 6}=2\sqrt{6}=DE[/tex]

Since ABCD is a rectangle, ∠D is a right angle. Then by the Pythagorean Theorem:

[tex](DE)^2+(DF)^2=(EF)^2[/tex]

Therefore:

[tex](2\sqrt6)^2+(2\sqrt6)^2=EF^2[/tex]

Square:

[tex]24+24=EF^2[/tex]

Add:

[tex]EF^2=48[/tex]

And finally, we can take the square root of both sides:

[tex]EF=\sqrt{48}=\sqrt{16\cdot 3}=4\sqrt{3}[/tex]

Answer:

4\sqrt3

Step-by-step explanation:

we know that the area is 6 * 8 = 48 cm^2. because triangle DEF is one fourth of that, triangle DEF's area would be 12.

to find the hypotenuse of triangle DEF, we would first need to find the bases (which have equal lengths). 1/2 * b * b = 12, so b^2 = 24. using the pythagorean theorem, we have \sqrt24 + \sqrt24 = h^2 which means h is the sqrt of 48. simplified, we have 4\sqrt3.

Explicación paso a paso:

Número de bolsas compradas = x

Costo total de compra = 675

Costo total de ventas = 1080

Beneficio por bolsa = 3

Por eso :

Beneficio total + costo total de compra = costo total de ventas

3x + 675 = 1080

3x = 1080 - 675

3 veces = 405

x = 405/3

x = 135
