jake added 1/8 cup of sunflower seeds and 4/5 cup of banana chips to his sundae. which is the best estimate of the total amount

bagirrra123 [75]

Jake added $\frac{37}{40}$ cup of toppings to his sundae.

Step-by-step explanation:

Given,

Amount of sunflower seeds added = $\frac{1}{8}\ of\ a\ cup$

Amount of banana chips added = $\frac{4}{5}\ of\ cup$

Total = Amount of sunflower seeds + Amount of banana chips

Total = $\frac{1}{8}+\frac{4}{5}$

Taking LCM = 40

$Total = \frac{5+32}{40}\\\\Total = \frac{37}{40}$

Jake added $\frac{37}{40}$ cup of toppings to his sundae.

A piggy bank contains a total of 84 coins in nickels and quarters worth $12.80.

Kitty [74]

Let's make a system of equations to solve for this:

n + q = 84

0.05n + 0.25q = 12.80

where n = nickels and q = quarters.

---

Solve for n in the first equation by subtracting q from both sides.

n = 84 - q

---

Plug n into the second equation.

0.05(84 - q) + 0.25q = 12.80

Distribute 0.05 inside the parentheses.

4.2 - 0.05q + 0.25q = 12.80

Combine like terms.

4.2 + 0.2q = 12.80

Subtract 4.2 from both sides.

0.2q = 8.6

Divide both sides by 0.2.

q = 43

---

Plug 43 for q in the first equation.

n + (43) = 84

Subtract 43 from both sides.

n = 41

---

There are 41 nickels and 43 quarters in the piggy bank. ✅

A news report states that the 99% confidence interval for the mean number of daily calories consumed by participants in a medica

expeople1 [14]

Answer:

The sample mean is of 1925 calories.

The margin of error is of 75 calories.

The sample standard deviation is of 109.7992 calories.

Step-by-step explanation:

Sample mean:

The sample mean is the mean value of the two bounds of the confidence interval. So

$M = \frac{1850 + 2000}{2} = 1925$

The sample mean is of 1925 calories.

The margin of error

Difference between the bounds and the sample mean. So

2000 - 1925 = 1925 - 1850 = 75 calories.

The margin of error is of 75 calories.

Sample standard deviation:

Here, I am going to expand on the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 18 - 1 = 17

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.99}{2} = 0.995$ . So we have T = 2.898

The margin of error is:

$M = T\frac{s}{\sqrt{n}}$

In which s is the standard deviation of the sample and n is the size of the sample.

Since $M = 75, T = 2.898, n = 18$

$M = T\frac{s}{\sqrt{n}}$

$75 = 2.898\frac{s}{\sqrt{18}}$

$s = \frac{75\sqrt{18}}{2.898}$

$s = 109.7992$

The sample standard deviation is of 109.7992 calories.
