Answer:

I'll help you! Answer is <u>3/2</u>. It's Friday so most people aren't on Brainly doing homework lol

Step-by-step explanation:

The heaviest bag (far right) weighs 4.75 lbs, whereas the lightest bag (far left) weighs 3.25 lbs. As mixed numbers, these would be 4\frac{3}{4}  and 3\frac{1}{4}. To find how much heavier the 4.75 lb bag is, you must subtract the 2 numbers.

<h3>Step 1. Convert each to a complex fraction</h3>

4\frac{3}{4}  =   \frac{19}{4}

  • Numerator = (4 x 4) + 3 = 19
  • Denominator = 4 (stays the same)

3\frac{1}{4}  =  \frac{13}{4}

  • Numerator = (3 x 4) + 1 = 13
  • Denominator = 4 (stays the same)

<h3>Step 2. Subtract fractions like normal </h3>

\frac{19}{4} - \frac{13}{4} =\frac{6}{4}

\frac{6}{4} =\frac{3}{2}  

<h3><u>Final answer: 3/2</u> <u>(</u>Hope this helps!)</h3>

A teacher was interested in knowing the amount of physical activity that his students were engaged in daily. He randomly sampled
klasskru [66]

Answer:

The standard error of the mean is 4.5.

Step-by-step explanation:

As we don't know the standard deviation of the population, we can estimate the standard error of the mean from the standard deviation of the sample as:

\sigma_{\bar{x}}\approx\frac{s}{\sqrt{n}}

The sample is [30mins, 40 mins, 60 mins, 80 mins, 20 mins, 85 mins]. The size of the sample is n=6.

The mean of the sample is:

\bar{x}=\frac{1}n} \sum x_i =\frac{30+40+60+80+20+85}{6}=52.5

The standard deviation of the sample is calculated as:

s=\sqrt{\frac{1}{n-1}\sum (x_i-\bar x)^2} \\\\ s=\sqrt{\frac{1}{5}\cdot ((30-52.5)^2+(40-52.5)^2+(60-52.5)^2+(80-52.5)^2+(20-52.5)^2+(85-52.5)^2}\\\\s=\sqrt{\frac{1}{5} *3587.5}=\sqrt{717.5}=26.8

Then, we can calculate the standard error of the mean as:

\sigma_{\bar{x}}\approx\frac{s}{\sqrt{n}}=\frac{26.8}{6}= 4.5

ruslelena [56]

Answer:

(b)(i) LCM of 45 and 50 = 450

Hence, it take 450 minutes until both ovens ding simultaneously.

(b)(ii) 450÷50=9 banana cakes baked

        450÷45=10 chocolate cakes baked.

Two numbers have a sum of 45. If one number is p, express the other number in terms if p.
iragen [17]
Heyo Kiddo. How are you doing today? 
Let's figure this out. 

So, if "one number is p," then we can say the other number can represent the variable z. 

We can conclude that: p + z = 45
 
For us to solve for z : 
 
p + z = 45
- p       -p

So then,
z = 45 - p 
You're welcome. :)
