Answer:
b. 0.02
Step-by-step explanation:
The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. In this case, this will mean rejecting that the proportions are not significantly different.
Usually, a p-value is considered to be statistically significant when p ≤ 0.05.
From the answer options provided, alternative b. 0.02 is the only one that represents the difference in proportions to be statistically significant (there is only a 2% chance that the proportions are not significantly different).
Therefore, the answer is b. 0.02
Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180
Answer:
0.1 yards of fabric
Step-by-step explanation:
Data provided in the question:
Number of outfits made for the doll = 14
Fabric used in each outfit = 
yards of fabric
Starting fabric available = 10 × 
or 
yards
Now,
The total fabric used in making the outfits of 14 dolls
= 14 × yards of fabric
= 
yards of fabric
Therefore,
The fabric left after making the outfits
= Fabric available in the start - Fabric used in making the outfits
= yards - yards
= 
yards
= 
yards
= 
yards
= 0.1 yards of fabric
Answer:
x = 9.6
Step-by-step explanation:
Before we can figure out what x is, we need to figure out what the unlabeled side is. To figure that out, multiply the hypotenuse (12) by the sine of the angle labeled (34)
12 * sin(34)
<em>sin(34) equals 0.559192903470747; I'll round it to 0.6 for convenience.</em>
12 * 0.6
<em>Now simply multiply 12 by 0.6 to get 7.2.</em>
The unlabeled side is approx. 7.2 units long.
Now we know what the unlabeled side is. Now, to find x, find the square root of 12 squared minus 7.2 squared.
x = √12² - 7.2²
<em>12 squared is 144; 7.2 squared is 51.84.</em>
x = √144 - 51.84
<em>Subtract 51.84 from 144 to get 92.16.</em>
x = √92.16
<em>The square root of 92.16 is 9.6 (on the spot!).</em>
x equals 9.6.
According to the conversion table we know,
1 meter = 100cm
This means if we need to convert meters to centimeters, we need to multiply by 100
Or
If we need to convert from centimeters to meters, we need to divide by 100.
Here the length of the wire needed to wrap 175 bundles = 2975 cm.
Now as we need to convert it to meters.
We need to divide this by 100.
We get
2975/100= 29.75
So 2975 cm = 29.75 m
Option D) is the right answer
