Answer: 196
Step-by-step explanation:
As per given , we have
Population standard deviation:
Significance level :
Using the z-value table , the critical z value for 98% confidence :
Margin of error : E= 01 lb
Sample size :
Simplify , we get
Hence, the minimum sample size required for books = 196
Answer:
a) Angle XBC = 55° because it's a corresponding angle
AXY = XBC
b) 180° - (55° × 2) = 70°
<span>If water and oil are combined in a container, the resulting liquid is a suspension. Water and oil do not mix. They form a heterogeneous mixture (a mixture whose composition is not uniform). The kind of heterogeous mixture that water and oil form is a suspension because the two lquids separate and can be easily distinguished. An emulsion, is an heterogenous mixture where small drops of one of the liquids disperse into the other liquid, so they form a stable mixture that will not separate quickly. Mayonaisse is an example of emulsion, because it consists of two liquids (oil an eggs) dispersed one into the other. Milk is also a emulsion of fat and water. So the specif term for the liquid resulting from water and liquid combined in a container is the option A. suspension.</span>
4x^2 = 100...divide both sides by 4
x^2 = 100/4
x^2 = 25....take the sqrt of both sides, eliminating the ^2
x = sqrt 25
x = 5 <===
