Let x be the amount invested in the first fund and y be the amount invested in the second fund.
Last your, the interest was $858 so: 0.092x + 0.03y = 942 (1) This year, the interest was$832 so:
0.10x + 0.01y = 867 2)
Solve by elimination. Here, I will eliminate y first. Multiply (2) by 3 to obtain (3): 0.30x + 0.03y = 2601 3)
Subtract each side of (1) and (3) and solve for x:
0.21x = —1659
$$\displaystyle{x}=—\frac{{1659}}{{-{0.21}}}$$
x=7900
Solve for y using (2): 0.10(7900) + 0.01y = 867
790+0.01y = 867
0.0ly = 77
y= 7700
So, the amounts invested are:
first fund $$\displaystyle—{>}\{7900}$$
second fund $$\displaystyle—\{7700}$$

The bulk density of soil is defined as the mass of dry solidsper unit bulk volume. A high bulk density implies a compact soilwith few pores. Bulk density is an important factor in influencing root development, seedling emergence, and aeration. Let X denotethe bulk density of Pima clay loam. Studies show that X is normally distributed with $$\displaystyle\mu={1.5}$$ and $$\displaystyle\sigma={0.2}\frac{{g}}{{c}}{m}^{{3}}$$.
(b) Find the probability that arandomly selected sample of Pima clay loam will have bulk densityless than $$\displaystyle{0.9}\frac{{g}}{{c}}{m}^{{3}}$$.
(c) Would you be surprised if a randomly selected sample of this type of soil has a bulkdensity in excess of $$\displaystyle{2.0}\frac{{g}}{{c}}{m}^{{3}}$$? Explain, based on theprobability of this occurring.

For several years, evidence had been mounting that folic acid reduces major birth defects. A. Czeizel and I. Dudas of the National Institute of Hygiene in Budapest directed a study that provided the strongest evidence to date. Their results were published in the paper “Prevention of the First Occurrence of Neural-Tube Defects by Periconceptional Vitamin Supplementation” (New England Journal of Medicine, Vol. 327(26), p. 1832). For the study, the doctors enrolled women prior to conception and divided them randomly into two groups. One group, consisting of 2701 women, took daily multivitamins containing 0.8 mg of folic acid, the other group, consisting of 2052 women, received only trace elements. Major birth defects occurred in 35 cases when the women took folic acid and in 47 cases when the women did not. a. At the 1% significance level, do the data provide sufficient evidence to conclude that women who take folic acid are at lesser risk of having children with major birth defects? b. Is this study a designed experiment or an observational study? Explain your answer. c. In view of your answers to parts (a) and (b), could you reasonably conclude that taking folic acid causes a reduction in major birth defects? Explain your answer. asked 2021-05-11 Bethany needs to borrow $$10,000.$$ She can borrow the money at $$5.5\%$$ simple interest for 4 yr or she can borrow at $$5\%$$ with interest compounded continuously for 4 yr. a) How much total interest would Bethany pay at $$5.5\%$$ simple interest? b) How much total interest would Bethany pay at $$5%$$ interest compounded continuously? c) Which option results in less total interest? asked 2020-11-10 A trust fund has$200,000 to invest. Three alternative investments have been identified, earning 10 percent, 7 percent, and 8 percent, respectively. A goal has been set to earn an annual income of \$16,000 on the total investment.
