Answer: we’ll first to find how “smart” you are, we have to verify the level of unsmartness and see if there is any given number. Since the is no given number we will use x as our unknown number. Then we will subtract 1 from 10, therefore giving us the number 9 that we will use in our equation to determine the level of “smart”.

Now we will put 9 and x together:

9x

Now we will find the next part of our equation which will find by looking at how we got the number 9, which is: 10-1

Now we group the parts of this equation which will be:

9x÷10-1

First we will solve one side of our equation

10-1=9

Then we will insert the solved side of the equation

9x÷9

Now we will divide

9/9x
we are left with 1

x=1

Now we insert our solved number back into our previous equation with 1 replacing x

9⋅1÷10-1

Now after we have solved the equation

The answer is: -0.1 will be your level of “smart”

Approximate the area under the
taurus [48]

Split up the interval [0, 3] into 3 equally spaced subintervals of length \Delta x = \frac{3-0}3 = 1. So we have the partition

[0, 1] U [1, 2] U [2, 3]

The left endpoint of the i-th subinterval is

\ell_i = i - 1

where i\in\{1,2,3\}.

Then the area is given by the definite integral and approximated by the left-hand Riemann sum

\displaystyle \int_0^3 f(x) \, dx \approx \sum_{i=1}^3 f(\ell_i) \Delta x \\\\ ~~~~~~~~~~ = \sum_{i=1}^3 (i-1)^3 \\\\ ~~~~~~~~~~ = \sum_{i=0}^2 i^3 \\\\ ~~~~~~~~~~ = 0^3 + 1^3 + 2^3 = \boxed{9}

The weight of tigers follow a normal distribution with a mean of 220 kg and a SD of 30 kg. 1) If we randomly select a tiger, wha
mylen [45]

Answer:

0.89736

Step-by-step explanation:

We solve this question using z score formula

Z score = x - μ/σ

x = raw score

μ = population mean

σ = population standard deviation

Hence,

x = 258, μ = 220, σ = 30

Z = 258 - 220/30

=1.26667

Probability value from Z-Table:

P(x<258) = 0.89736

Therefore, the probability that his weights is less than 258 kg is 0.89736

Pls help I dont know how to do this​
german

Answer:

  • 1. CE = 63
  • 2. x = 16

Step-by-step explanation:

Use proportions to solve.

Corresponding sides have same ratio.

<u>Question 1</u>

  • DE/EG = CE/EF
  • (6x + 3)/17 = (8x - 1)/21
  • 21(6x + 3) = 17(8x - 1)
  • 126x + 63 = 136x - 17
  • 10x = 80
  • x = 8
  • CE = 8*8 - 1
  • CE = 63

<u>Question 2</u>

  • KM/MD = KZ/ZH
  • (x + 8)/21 = 32/28
  • x + 8 = 21*8/7
  • x + 8 = 24
  • x = 24 - 8
  • x = 16
