The farmer had 28 cows. He wanted to bring them into the milking shed in groups of 7. How many groups of cows did the farmer bri

Ostrovityanka [42]

Answer:

(C) Subtract 7 from 28. Keep subtracting 7 from answer until he gets to 0. Then count the number of times 7 was subtracted.

This method is another suitable solution to problem

Step-by-step explanation:

Total number of cows the farmer has = 28 cows

Number of cows in 1 shed = 7

The number of sheds used to keep 28 cows is 28 ÷ 7 = 4 sheds

⇒4 sheds are needed to keep 28 cows.

Now choosing an alternate method:

1) Add 28 and 7 = 28 + 7 = 35 sheds

But 35 sheds ≠ 4 sheds

Hence, NOT AN APPROPRIATE METHOD.

2)Add 7 to 28. Keep adding 7 to the answer for a total of seven times.

28 + 7 .... 7 times = 28 + 7 + 7 + 7 + 7 /+ 7 + 7 + 7 = 77 ≠ 4 sheds

NOT AN APPROPRIATE METHOD.

3)Subtract 7 from 28. Keep subtracting 7 from answer until he gets to 0.

28 - 7 = 21

21 - 7 = 14

14 -7 = 7 and 7 - 7 - 0

Hence, in 4 times the answer is 0

So, the number of sheds required is 4

AN APPROPRIATE METHOD.

4) Multiply 28 by 7.

28 x 7 = 196, 196 ≠ 4 sheds

NOT A APPROPRIATE METHOD.

Hence, the ONLY alternate method to count the totals sheds required is

Subtract 7 from 28. Keep subtracting 7 from the answer until he gets to 0.

The compound interest will be equal to $13.57.

<h3>What is compound interest?</h3>

The interest on a loan or deposit that accrues on both the initial principal and the accumulated interest from prior periods is known as compound interest.

The compound interest will be calculated by:-

$CI = P(1+\dfrac{r}{12})^{12t}-P$

$CI = 250(1+\dfrac{0.053}{12})^{12}-250$

CI = $13.57

Therefore the compound interest will be equal to $13.57.

worty [1.4K]

Answer:

95% confidence interval for the true mean cholesterol content of all such eggs.

(173.8175 , 196.1825)

Step-by-step explanation:

Step(i):-

Given mean of the sample x⁻ = 185 milligrams

Given standard deviation of the sample 'S' = 17.6 milligrams

Level of significance

∝ = 0.05

$t_({\frac{\alpha }{2} , n-1 }) = t_{0.025 ,11} = 2.2010$

Step(ii):-

95% confidence interval for the true mean cholesterol content of all such eggs.

$(x^{-} - t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} } , x^{-} + t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} })$

$(185 - 2.2010 \frac{17.6}{\sqrt{12} } , 185 + 2.2010 \frac{17.6}{\sqrt{12} })$

( 185 - 11.1825 , 185 + 11.1825)

(173.8175 , 196.1825)

Final answer:-

95% confidence interval for the true mean cholesterol content of all such eggs.

(173.8175 , 196.1825)

Find the slope and the y-intercept of the graph of the linear equation. y=−6−23x

Debora [2.8K]

Answer:

Step-by-step explanation:

this equation is written in y = mx + b form

m = slope

b = the y intercept

so if we rearrange the equation to

y = -23x -6

the slope is -23

the y intercept is (0, -6)
