Answer:
A technique presently used through docs to display screen ladies for breast most cancers fails to observe most cancers in 15% of the girls who without a doubt have the disease. A random pattern of eighty girls acknowledged to have breast most cancers are to be screened the use of a new technique that researchers suppose will be capable to realize most cancers greater accurately. At the 0.05 stage of significance, the researchers will be capable to conclude that the new approach is higher than the present day one if the fantastic.
Answer::: greater than 1.645
The triangles are similar so the angles are equal
2x^2 - 2 = 10x - 2
2x^2 - 2 - 10x + 2 = 0
2x^2 - 10x = 0
2x(x - 5) = 0
2x = 0 OR x - 5 = 0
x = 0 OR x = 5
0 doesn't make sense, because IF I plug 0 into 2x^2 - 2 I get a negative number. We need to use 5 to find the angle measure
2(5^2) - 2 = 2(25) - 2 = 50 - 2 = 48 degrees or the measure of CED
Answer:
Step-by-step explanation:
b + n = 192
n = 5b
b + 5b = 192
6b = 192
b = 192/6
b = 32 <==== 5 beads per bracelet
n = 5b
n = 5(32)
n = 160 <==== 160 beads per necklace
Answer:
82 minutes.
Step-by-step explanation:
So first calculate the percentage 37 minutes is. It is 45%
Next find how much 1% is.
Divide by 45.
Multiply by 100 to find how much the whole time is: 
The decimal version is: 82.2222222222...
Which simplifies to 82 minutes.
