answer:
$14
step-by-step explanation:
the formula for simple interest is-
i=prt
meaning interest=principal (the starting amount of money) * rate * time
=200*0.01*7
(we have to turn 1% into a decimal so 1/100=0.01)
=14
i=14
good luck :)

After 7 years and a 1% interest rate, Brendan will have a total of 214$.
What is simple interest?
Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.
Given, Brendan has $200 in a saving account with a 1% interest rate.
The simple interest is given as
Interest = (PRT/100)
where
P = Amount deposited = 2,00
R = Rate = 1%
T= Time = 7 years
Interest = (PRT/100)
Interest = (200 × 7 × 1/100)
Interest = 14
Total amount = SI + principal amount
Total amount = 14 + 200 = 214
Therefore, Brendan will have 214 $ after 7 years and a 1% interest rate.

Write the equation of the circle with the given information.
Center: (-8, 0)
Diameter: 5
Answer:
(x + 8)² + y² = 6.25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 8, 0 ) and r = 5 ÷ 2 = 2.5 , then
(x - (- 8))² + (y - 0)² = 2.5² , that is
(x + 8)² + y² = 6.25

A national study, that revealed a normal distribution, revealed that the average time a student spends studying statistics on a weekend is 60 minutes. A random sample of 11 students in BU 203 were asked to record their statistic study time over a weekend. The sample revealed an average study time of 44.27 minutes with a standard deviation of 20.4. With an alpha of 5% State the null hypothesis (H0) and the alternate hypothesis (H1). Draw the distribution.
Answer:
Null hypothesis = H0 : μ = 60
Alternative hypothesis = H1 : μ < 60
Step-by-step explanation:
From the question given :
μ = 60 minutes
xbar = 44.27 minutes
s = 20.4 minutes
The alternative hypothesis is the claim ; which is to hypothesize that the average studying time is 44.27 (which is less than the population average studying time)
The null hypothesis is the initial truth and it is the opposite of the alternative hypothesis.
The hypothesis are :
H0 : μ = 60
H1 : μ < 60

The series diverges because it has a sum of 4.
The series converges because it has a sum of 4.
The series diverges because it does not have a sum.
The series converges because it does not have a sum.
Answer: B
The series converges because it has a sum of 4.
Step-by-step explanation:
The convergence or divergence of a series depends on the sum of the series and its common ratio. The series converges because its sum is b
The series is given as:
[tex]\sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^n[/tex]
A geometric series is given as:
[tex]T_n = ar^{n-1}[/tex]
So, we rewrite the series as follows:
[tex]\sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^n = \sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^n[/tex]
Apply law of indices
[tex]\sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^n = \sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^{n-1} \times (\frac{2}{3})[/tex]
Rewrite
[tex]\sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^n = \sum\limits^{\infty}_{n=1} 2 \times (\frac{2}{3})(\frac{2}{3})^{n-1}[/tex]
[tex]\sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^n = \sum\limits^{\infty}_{n=1} \frac{4}{3}(\frac{2}{3})^{n-1}[/tex]
So, we have:
[tex]T_n = \frac{4}{3}(\frac{2}{3})^{n-1}[/tex]
Compare the above series to: [tex]T_n = ar^{n-1}[/tex]
[tex]a = \frac{4}{3}[/tex]
[tex]r = \frac{2}{3}[/tex]
The sum of the series to infinity is:
[tex]S_{\infty} = \frac{a}{1 - r}[/tex]
So:
[tex]S_{\infty} = \frac{4/3}{1 - 2/3}[/tex]
[tex]S_{\infty} = \frac{4/3}{1/3}[/tex]
[tex]S_{\infty} = 4[/tex]
i.e. [tex]\sum\limits^{\infty}_{n=1} 2 (\frac{2}{3})^n = 4[/tex]
Also:
The common ratio (r)
[tex]r = \frac{2}{3}[/tex]
[tex]r = \frac{2}{3}[/tex] [tex]< 1[/tex]
When common ratio is less than 1, then such series is convergent.
Hence, (b) is true because it has a sum of 4

The number of baby carrots in a bag is normally distributed with a mean of 94 carrots and a standard deviation of 8.2 carrots.
Approximately what percent of the bags of baby carrots have between 90 and 100 carrots?
23.3%
31.2%
45.5%
76.73%
Answer:
46% is the percent of the bags of baby carrots that have between 90 and 100 carrots
Step-by-step explanation:
The baby carrot is normally distributed.
z = (x - µ)/σ
x is equal to number of baby carrots
µ = mean
σ = standard deviation
Substituting the given values, we get -
90 ≤ x ≤ 100
z = (90 - 94)/8.2 = - 0.49
For z value of -0.49, the probability is 0.31
For x = 100
z = (100 - 94)/8.2 = 0.73
For z value of 0.73, the probability is 0.77
P(90 ≤ x ≤ 100) = 0.77 - 0.31 = 0.46
The percent of the bags of baby carrots having carrots between 90 and 100 carrots is 0.46 × 100 = 46%

Solve the equation 40 = -10(y+0.3). what does the y equal
Answer:
y = -4.3
Step-by-step explanation:
40 = -10(y + 0.3) {Step 1: Use the distributive property to multiply -10 by y + 0.3}
40 = -10y + -10(0.3)
40 = -10y - 3 {Step 2: Add 3 to both sides.}
40 + 3 = -10y
43 = -10y {Step 3: Divide both sides by -10}
43/-10 = y
-4.3 = y
y equals -4.3.
Answer:
y = -4.3
Step-by-step explanation:
40 = -10(y + 0.3)
40 = -10y - 3
-3. -3
43 = -10y
Divide 43 by -10
y equal 4.3

(a) b1 and b0
[tex]b_1 = 3.372767857[/tex]
[tex]b_1 \approx 3.4[/tex]
[tex]b_0 = 83.65625[/tex]
[tex]b_0 \approx 83.7[/tex]
(b) The estimated regression equation
The equation is of the form:
[tex]y =b_0 + b_1x[/tex]
Where:
[tex]b_1 =3.4[/tex]
[tex]b_0 =83.7[/tex]
So:
[tex]y=83.7+3.4 x[/tex]
(c) The coefficient of determination (r^2)
[tex]r^2 = 0.790361699[/tex]
[tex]r^2 \approx 0.790[/tex]
(d) Percentage of variation
To do this, we simply convert r^2 to percentage
[tex]\% Variation = r^2 * 100\%[/tex]
[tex]\% Variation = 0.790 * 100\%[/tex]
[tex]\% Variation = 79.0\%[/tex]
(e) Expected annual sales of a sales person with 8 years of experience.
Using the regression equation
[tex]y=83.7+3.4 x[/tex]
Where
[tex]x = 8[/tex] --- the years of experience.
So;
[tex]y = 83.7 + 3.4 * 8[/tex]
[tex]y = 83.7 + 27.2[/tex]
[tex]y = 110.9[/tex]
The expected earnings is: $110,900
