The smallest square number which can be divisible by 11 and 5​
Elena L [17]

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

\sqrt{55x}  =  \sqrt{5 \times 11 \times x}

the smallest value of x to make 55x a perfect square is....

x = 11 \times 5 = 55

Therefore the number is.... .

55x = 55(55) = 3025

Does the sample provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package? Gro
kirill115 [55]

Answer:

As probability of that happening is very small; Yes, 33.6 is less than 35.6 grams   because   it  provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.

Step-by-step explanation:

For a normal distribution Z-score

Z = \frac{X-\mu}{\sigma}

Given that :

the mean (\mu) = 35.6

standard deviation (\sigma) = 5.2

sample size (n) = 35

standard error: \sigma_x = \frac{\sigma}{\sqrt{n}}

\sigma_x = \frac{5.2}{\sqrt{35}}

\sigma_x = 0.879

The probability that a random sample of 35 bags has a mean weight of 33.6 grams or less is :

P(X<33.6)  = P(Z < - 2.28)

= 0.0114

Conclusion:

As probability of the happening is very small; Yes, 33.6 is less than 35.6 grams   because   it  provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.

Find the values of x and y in the parallelogram.
ValentinkaMS [17]
Answer:
x = 20
y = 8

In a parallelogram, there are always two pairs of equal sides, where in this question:

Side CD = Side BA
Side DA = Side CB

Use this to find x and y.

CD = BA
15 = x - 5
x = 20 (rearranging to find x)

DA = CB
y = 8
