How do we calculate length without points given? ​

Answer:

To divide by (x+1) in synthetic division, you divide by -1.

-1    1   -7   4   12

         -1    8   -12

—————————-

     1   -8   12   0

This gives us x^2 -8x +12x  which factors to (x-2) (x-6).  We still have the factor of (x+1)  so the zeros will be 2, 6, and -1.

Answer:

B. 2s + 100 when s=80 the latest balance of Ahmed’s savings is $260

Step-by-step explanation:

We are given that the savings = $s and current amount  $c.

Now, Ahmed has doubled his savings. This means that the new savings = $2s

Also, he had deposited $100.

So, the current amount of Ahmed is given by c = 2s + 100.

Moreover, if the savings is $80 i.e. s = 80, the current amount is,

c = 2 × 80 + 100

i.e. c = 160 + 100

i.e. c = 260

So, the current amount if savings is $80 is $260.

Hence, the expression for current amount is 2s + 100 and if s = 80, the current amount is $260.

For given question,

Charlotte the turtle was born with 4 squares on her shell, as in the first picture below.

When she was 1 year old, 12 new squares appeared around the old squares, as in the second picture below.

Each year, a new group of squares appeared around the old squares.

We find the same pattern to find the new squares appeared when she is 2 and 3 years old.

When she is 2 years old then the new squares appeared around the old squares, as shown below.

There are 20 new squares appeared around the old squares.

When she is 3 years old then the new squares appeared around the old squares, as shown below.

There are 28 new squares appeared around the old squares.

Therefore, when age is 2 then the new squares appeared = 20

when age is 3 then the new squares appeared = 28

Maximum 75

Step-by-step explanation:

If you notice, there are 5 distinguished points of data, and I used all the points for each thing you asked for. You just have to recognize the minimum and maximum are the largest and smallest of all the data, and there is clearly nothing outside of the range of 56-75. then Q1, Q2, and Q3 are on the box itself. The median, just like with numbers, will always be the middle line. It is not directly in the center because there are more people in the 65-75 value range than the 56-65 value range.

The probability that Dan buys a sandwich and gets the bus will be 0.16.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

The probability that Dan buys a sandwich is 0.2.

The probability that Dan gets the bus is 0.8.

Assuming the events are independent.

Then the probability that Dan buys a sandwich and gets the bus will be

P = 0.2 × 0.8

P = 0.16

Answer:

[tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]

Step-by-step explanation:

The equation of the curve is

[tex]Y = sin^{-1}(7x)[/tex]

To find the equation of tangent we need to differentiate this equation w.r.t x

So, differentiating we get

[tex]Y'=\frac{7}{\sqrt{1-49x^2} }[/tex]

This would give the slope of the tangent line at any given point of which x coordinate is known. In the present case it is  [tex]x = \sqrt{\frac{1}{7} }[/tex]

Then slope would accordingly be

[tex]Y'=\frac{7}{\sqrt{1-49/49} }[/tex]

= ∞

For, [tex]x = \sqrt{\frac{1}{7} }[/tex], [tex]Y = sin^{-1}(7/7)= \pi/2[/tex]

Equation of tangent line, in the point slope form, would be [tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]

Answer:

[tex]P(Z<-2.5) =0.0062097[/tex]

Step-by-step explanation:

From the question we are told that:

Test statistic t =-2.5

Generally the equation for Test for statistics is mathematically given by

 [tex]t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }[/tex]

 [tex]t=-2.5[/tex]

Therefore

P-value from Z table is

For left tailed test

 [tex]P(Z<-2.5) =0.0062097[/tex]

therefore the P-value for the test is

 [tex]P(Z<-2.5) =0.0062097[/tex]

Answer:

31 1/6 feet

Step-by-step explanation:

add 25 2/3 to 5 1/2 to see how far under the surface he is; use common denominator of 6

25 4/6 + 5 3/6 = 30 7/6

30 7/6 is the same as 30 + 1 1/6 so diver must ascend 31 1/6 feet

The mean is 8 and the lower quartile is 6.

Answer:

6.16 hours

Step-by-step explanation:

Let the number of hours that washed the car together = T

Number of hours Matthew washed = m = 14 hours

Number of hours Arianna washed = a = 11 hours

The formula to calculate how many they wash the cars together is given as

1/a + 1/m = 1/T

1/14 + 1/11 = 1/T

Lowest Common Denominator = 154

Hence:

(11 + 14)/154 = 1/T

25/154 = 1/T

Cross Multiply

154 × 1 = 25 × T

T = 154/25

T = 6.16 hours

Therefore, it will take Matthew and Arianna 6.16 hours to wash the cars together

Answer:

below

Step-by-step explanation:

A)1 can be interpreted as the job, the project, the whole thing or all of the cars

B)rate* time = amount of work (a bit like rate*time = distance for figuring how far you go at a certain speed)

C)multiply both sides by 14 hours/1 job and simplify to get t=14hours

D) ok, now we do the 2nd fraction 1/11 we want its bottom to be 154, like: 1/14 - 11/11

Answer:

Step-by-step explanation:

Select the correct answer from each drop-down menu.

We solve using z score formula

z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard deviation of 25 minutes.

a) The probability of a randomly selected student completing the test in 45 minutes or less is approximately equal to %.

z = 45 - 70/25

b) The probability of a randomly selected student completing the test in 95 minutes is %.

z = 95 - 70/25

Answer:

42.5 Cubic Yards

Step-by-step explanation:

To find volume of a rectangle you do length*width*height to get the volume, so 17*15*0.5(because 6 inches is half of a foot) you get 127.5, but they're asking for it in yards not feet so you need to divide 127.5 by 3 and that will give you 42.5.

The volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.

The volume of the cuboid is the space occupied by the 3D object cuboid. It is the product of the length, width, and depth of the cuboid.

As it is given that we need to make a rectangular foundation, therefore, the shape of the foundation will be a cuboid with sides 5 feet wide, 17 feet long, and depth of 6 inches.

Now, as we know large amounts of concrete can be purchased by the cubic yard only, therefore, we will convert each of the sides of the rectangular foundation into yards.

[tex]\rm Wide, w = 5\ feet = 5 \times \dfrac{1}{3} = \dfrac{5}{3}\ yards\\\\Length, L = 17 feet = 17 \times \dfrac{1}{3} = \dfrac{17}{3}\ yards\\\\Depth, D = 6\ inches = 0.5\ feet = 0.5 \times \dfrac{1}{3} = \dfrac{0.5}{3}\ yards\\\\[/tex]

Now, we know that the volume of the cuboid is given as the product of its length, width, and depth. therefore,

[tex]\text{Volume of Cuboid} = Length\times Width\times Depth[/tex]

                             [tex]= \dfrac{5}{3} \times \dfrac{17}{3} \times \dfrac{0.5}{3}\\\\= \dfrac{42.5}{27}\\\\=1.574\rm\ yards^3[/tex]

Hence, the volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.
