Answer:

Step-by-step explanation:

The formula for Pythagoras's theorem is given by a^2 + b^2 = c^2

Area of a square is given by length * length = L^2

In this case,

The length of the 2 smaller squares are 3 and 4 respectively,

Square A = 3, Square B = 4

Its area (can be counted by the number of small boxes) = 9 and 16 boxes respectively.

The biggest Square C has length of 5 boxes and an area of 25 boxes.

Now Square A + Square B = Square C,

which is 9 + 16 = 25 as shown.

We also know the Area of a square is given by length * length

Thus, re-writing the area as length * length,

We have 3^2 + 4^2 = 5^2,

which checks out with the formula of a^2 + b^2  = c^2.

In a survey of 1,532 former UF students, 84% said they were still in love with Tim Tebow. The survey's sampling error was 2%. Us
nalin [4]

Answer:

confidence interval for the proportion of all former UF students who are still in love with Tim Tebow.

(0.79 , 0.89)

Step-by-step explanation:

step 1:-

Given sample survey former UF students n = 1532

84% said they were still in love with Tim Tebow

p = 0.84

The survey sampling error

                                                 = \sqrt{\frac{p(1-p)}{n} }

Given standard error of proportion = 2% =0.02

<u>Step 2</u>:-

The 99% of z- interval is 2.57

The 99% of confidence intervals are

p ± zₐ S.E     (since sampling error of proportion = \sqrt{\frac{pq}{n} }

(0.84 - 2.57X0.02 , 0.84 + 2.57X0.02)

on simplification , we get

(0.84 - 0.0514 , 0.84 + 0.0514)

(0.79 , 0.89)

<u>conclusion</u>:-

confidence interval for the proportion of all former UF students who are still in love with Tim Tebow.

(0.79 , 0.89)

Actual lengths of pregnancy terms for a particular species of mammal are nearly normally distributed about a mean pregnancy leng
HACTEHA [7]

Solution :

The data is normally distributed.

The standard deviation is 18 days

Here the data is normally distributed and 54 days is 3 days of standard deviation.

Therefore, the percentage of the births that would be \text{expected to occur} within the 54 days of the mean \text{pregnancy} length is given by :

= P( -3 < Z < 3)

= 0.9544

= 95 %

Therefore, about 95% of the births would be \text{expected to occur} within 54 days of the men \text{pregnancy} length.

Can you subtract closed polynomials
netineya [11]

Answer:

Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.
