Well I can see where you have the issue. This is actually a simple fraction problem. Let's begin.

Step 1: Determine the prices of the fabric, per every 10th of a meter.
Since we know that 10/10 of a meter=1 meter, divide 3.30 by 10 to get the price per 10th of a meter which is .33.

Step 2: Determine the price of the blue fabric.
Since the blue fabric requires 2.3 meters (or 23/10) we can multiply .33 by 23 and have the pricing for the blue fabric, which is 7.59.

Step 3: Determine the price of the white fabric.
Since we know that there is 3.5 meters of white fabric (or 35/10) we can multiply .33 by 35 and again have the pricing, which is 11.55.

Step 4: Determine the price of the red fabric.
Since we know that the costume requires 0.6 meters of red fabric (or 6/10) we multiply .33 by 6 and get the pricing for red, which is 1.98.

Step 5: Add these three numbers up to get the total price of the costume.
7.59+11.55+1.98=21.12

Step 6: Subtract the cost of the fabric from the total budget to see how much money Kelly has left.
40.00-21.12=18.88

Since the problem does not specify any other costs other than the fabric and accessories, the assumed amount left for accessories is C: $18.88

The volume of a shampoo filled into a container is uniformly distributed between 370 and 385 milliliters. (a) What are the mean
Olenka [21]

Answer:

(a) mean = 377.5ml. standard deviation = 4.33

(b) 0.333

(c) 384.25 ml

Step-by-step explanation:

(a)The mean:

\mu = \frac{385 + 370}{2} = 377.5 ml

The standard deviation:

\sigma = \frac{385 - 370}{\sqrt{12}} = 4.33

(b)

P(x < 375) = \frac{375 - 370}{385 - 370} = \frac{1}{3} \approx 0.333

(c)P(x > m) = 0.95

\frac{m - 370}{385 - 370} = 0.95

m - 370 = 14.25

m = 384.25ml

So the volumn of shampoo should be 384.25ml to exceed 95% of containers.

Aleksandr-060686 [28]
  • x-y-z

\\ \sf\longmapsto XY+YZ=XZ

\\ \sf\longmapsto 7a+5a=6a+24

\\ \sf\longmapsto 12a=6a+24

\\ \sf\longmapsto 12a-6a=24

\\ \sf\longmapsto 6a=24

\\ \sf\longmapsto a=\dfrac{24}{6}

\\ \sf\longmapsto a=5

  • YZ=5a=5(5)=25
