Answer:

9 units squared

Step-by-step explanation:

There are 6 units going up from the origin, and 3 units going right.

Do 6 x 3 = 18

18 divided by 2 because area for triangles is length x width divided by 2.

18 divided by 2 = 9

add units of measurements

Can u guys PLEASE answer this question ASAP.

Answer:

1. Interest: $166.67

Principal: $6,166.67

2. Interest: $200.00

Principal: $5,200.00

Explanation:

1. $6000 for 50 days at 20% p.a

In 20% pa, pa means "per annum", i.e. "per year".

Assume simple interest:

Principal: $6,000

interest: 20% pa

time = 50 days

Interest:

Interest = Principal × number of days × annual rate / 360

Interest = $6,000 × 50 × 20% / 360 = $166.67

Principal = principal + interest = $6,000 + $166.67 = $6,166.67

2. $5000 for 5 months at 0.8% per month

Assume, again, simple interest.

Principal: $5,000

interest: 0.80% per month

time = 5 months

Interest:

Interest = Principal × number of months × montly rate

Interest = $5,000 × 5 × 0.80% = $200.00

Principal = principal + interest = $5,000 + $200.00 = $5,200

You can see that the accrued interests depend on the principal, the interest rate, and the time.

Express the product shown as a fraction in simplest form -3/7 dot -2/3 please help

attashe74 [19]

The answer is $\frac{2}{7}$ .

Multiple numerators by nums, and denoms by denoms.

$\\\frac{-3}{7}$ · $\frac{-2}{3}$ = $\frac{6}{21}$

$\frac{6}{21}$ simplified is $\frac{2}{7}$

Hope this helped and branluest would be appreciated

the performance score of 10 adults is recorded, and the results are 83 87 90 92 93 100 104 111 115 121 find the standard deviati

luda_lava [24]

Answer:

The standard deviation of the data set is $\sigma = 12.7906$ .

Step-by-step explanation:

The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma)

To find the standard deviation of the following data set

$\begin{array}{cccccccc}83&87&90&92&93&100&104&111\\115&121&&&&&&\end{array}$

we use the following formula

$\sigma = \sqrt{ \frac{ \sum{\left(x_i - \overline{X}\right)^2 }}{n-1} }$

Step 1: Find the mean $\left( \overline{X} \right)$ .

The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:

$Mean = \frac{Sum ~ of ~ terms}{Number ~ of ~ terms}$

$Mean = \frac{Sum ~ of ~ terms}{Number ~ of ~ terms}=\frac{83+87+90+92+93+100+104+111+115+121}{10} \\\\Mean = \frac{996}{10} =\frac{498}{5}=99.6$

Step 2: Create the below table.

Step 3: Find the sum of numbers in the last column to get.

$\sum{\left(x_i - \overline{X}\right)^2} = 1472.4$

Step 4: Calculate σ using the above formula.

$\sigma = \sqrt{ \frac{ \sum{\left(x_i - \overline{X}\right)^2 }}{n-1} } = \sqrt{ \frac{ 1472.4 }{ 10 - 1} } \approx 12.7906$
