Answer:

110 stones

Step-by-step explanation:

Using your conversion factors, you get ...

$0.7\text{ T}\cdot\dfrac{1000\text{ kg}}{1\text{ T}}\cdot\dfrac{2.2\text{ lb}}{1\text{ kg}}\cdot\dfrac{1\text{ st}}{14\text{ lb}}=\dfrac{0.7\cdot1000\cdot2.2}{14}\text{ st}\\\\=\boxed{110\text{ st}}$

<em>Additional comment</em>

The exact conversion between kg and pounds is 1 lb = 0.45359237 kg. The number 2.2 is approximate, low by approximately 0.21%.

Answer: 0.50477

Step-by-step explanation:

Given : The sugar content of the syrup is canned peaches is normally distributed.

We assume the can is designed to have standard deviation $\sigma=5$ milligrams.

The sampling distribution of the sample variance is chi-square distribution.

Also,The data yields a sample standard deviation of $s=4.8$ milligrams.

Sample size : n= 10

Test statistic for chi-square : $\chi^2=\dfrac{s^2(n-1)}{\sigma^2}$

i.e. $\chi^2=\dfrac{(4.8)^2(10-1)}{(5)^2}=8.2944$

Now, P-value = $P(\chi^2>8.2944)=0.50477$ [By using the chi-square distribution table for p-values.]

Hence, the chance of observing the sample standard deviation greater than 4.8 milligrams = 0.50477

Answer:

$-2x^2-8x+12$

Step-by-step explanation:

$f-g=(3x^2-2x+4)-(5x^2+6x-8)=3x^2-2x+4-5x^2-6x+8=\\ =-2x^2-8x+12$

Answer:

Step-by-step explanation:

step 2 : x + 3 = 0 and x - 5 = 0 ← correct

step 3

x = 3 and x = - 5 ← error made here with signs, correct statement should be

x + 3 = 0 ⇒ x = - 3

x - 5 = 0 ⇒ x = 5
