Catherine kept track of her math test scores for the first and second semesters. She organized her data into the following table. Test Scores Test 1 Test 2 Test 3 Test 4 Test 5 Test 6 Semester 1 65 80 93 92 92 95 Semester 2 90 93 88 90 95 92 Click on two true statements about Catherine's test scores. A. Her mean test scores were the same for both semesters, B. Her mean test score was higher during Semester 1 than Semester 2. C. Her mean test score was higher during Semester 2 than Semester 1. D. Her median test score was higher during Semester 1 than Semester 2. E. Her median test score was higher during Semester 2 than Semester 1. ​

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

hello umm i don't understand your question can you explain it more pls

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
