A tailor used 6 2/3 yards of fabric to make hats. The amount of fabric needed to make each hat is 5/6 yard. How many complete hats did the tailor make?
Answer: The tailor made 8 complete hats
Step-by-step explanation:
Amount of fabrics available to make hat = 6 2/3 yards
1 hat requires = 5/6 yards
Number of hat to obtain from the available fabric = Amount of fabrics available to make hat / requirement of 1 hat
=(6 2/3) / (5/6)
(20/3) / (5/6)
20/3 x 6/5 = cancelling out, we are left with
4x2= 8 hats
or
(20/3) / (5/6)
6.6666 /0.83333
= 8.00002= 8 hats

A cell phone is 84 mm long and 46 mm wide. What is the ratio of the widty to the length?
Answer:
23/42
Step-by-step explanation:
width/length
46/84
=23/42
23:42
=.5476
The ratio of the width to the length of the cell phone will be 42: 23.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Division means the separation of something into different parts, sharing of something among different people, places, etc.
A cell phone is 84 mm long and 46 mm wide.
Then the ratio of the width to the length will be calculated by the division of the number 84 by 46. Then we have
⇒ 84 / 46
⇒ 42 / 23
The ratio of the width to the length of the cell phone will be 42: 23.

What is the equation of the line that passes through the point (-7, 2) and has a
slope of -1?
Answer:
Point-Slope Form: y-2 = -1(x+7) Slope-Intercept Form: y = -x-5 Standard Form: x+y = -5
Step-by-step explanation:
Because we were giving the slope and a point, we can write this in point-slope form.
Point-Slope Form: y-y1=m(x-x1)
Substitute the point and slope into (x1,y1) and m: y-2 = -1(x-(-7))
y-2 = -1(x-(-7)) = y-2 = -1(x+7)
y-2 = -1(x+7)
If want in slope-intercept form (y=mx+b),
y-2 = -1(x+7)
y-2 = -1x-7
y = -1x-5 = y = -x-5
To convert to standard form (ax+by=c)
y = -x-5
y+x = -5 = x+y = -5

A distribution is given as X ~ U(0, 12). Find P(x > 6). (Enter an exact number as an integer, fraction, or decimal.)
Answer:
Step-by-step explanation:
The value of P(x>6) is 1/5.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given that A distribution is given as X ~ U(0, 12).
We need to find the value of P(x > 6)
The probability density function of the uniform distribution is defined as:
f(x)=1/b-a, a<x<b
a=0 and b=12
f(x)=1/12 , 0<x<12
The required probability is P(x>6)
Now P(x>6)= [tex]\int\limits^2_6 {f(x)} \, dx[/tex]
P(x>6)=(12/12-6/12)
=1-1/2
=1/2=0.5
Hence, the value of P(x>6) is 1/5.

7. A restaurant owner wants to see if there is a relationship between the amount of
sugar in some food items on her menu and how popular the items are.
She creates a scatter plot to show the relationship between amount of sugar in menu
items and the number of orders for those items. The correlation coefficient for the
line of best fit is 0.58.
a. Are the two variables correlated? Explain your reasoning.
b. Does either of the variables cause the other to change? Explain your reasoning.
Answer:
a) Yes, the two variables correlated
b) Yes, variation of sugar changes the number of orders for item containing sugar
Step-by-step explanation:
a) Yes the two variables are moderately co-related as the value of co-relation lies between 0.5 and 0.7
b) Yes the variation in amount of sugar leads to variation in the number of orders with sugar.
The manager of a customer support center takes an SRS of 40 reported issues and finds that 22% of the sampled issues required more than one call to resolve. The manager may take an SRS like this each month. Suppose that it is really an average of 25% of the approximately 1000 issues reported per month that require more than one call.
Let represent the proportion of a sample of 40 reported issues that require more than one call to resolve. What are the mean and standard deviation of the sampling distribution of p?
Answer:
The mean of the sampling distribution of p is 0.25 and the standard deviation is 0.0685.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
25% of the approximately 1000 issues reported per month that require more than one call.
This means that [tex]p = 0.25[/tex]
What are the mean and standard deviation of the sampling distribution of p?
Sample of 40 means that [tex]n = 40[/tex].
By the Central Limit Theorem,
The mean is [tex]\mu = p = 0.25[/tex]
The standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.25*0.75}{40}} = 0.0685[/tex]
The mean of the sampling distribution of p is 0.25 and the standard deviation is 0.0685.

The different possibilities for flipping two coins are:
TT
TH
HT
HH
Only 1/4 is two heads.
Since you're finding the best prediction possible for the number of times both coins will land on heads out of 4 times, that means its 1/4 * 4 = 1 time
Answer:
1/4 is the probablity
Step-by-step explanation:
if you flip 2 coins one time the no.of outcome are 4 if you flip is 4 time no.of outcomes are 16
P(E)= favourable outcomes/ total no.of outcomes
= 4/16
= 1/4
