we know that

Using the original score as the basis

If Misha increased her test score from 60% to 80%

then

the increase variation is equal to

80%-60%=20%


to find the approximate percent increase of Misha's test score we apply a rule of three

if 60%--------------> represents 100%

20%----------------->x

x=20*100/60

x=33.33%

therefore


the answer is

the approximate percent increase of Misha's test score is 33%

Klio2033 [76]

Answer:

$9.47

Step-by-step explanation:

Add all her purchases together

97.62 + 22.95 + 14.78 = 135.35

The total tax is 6.5% sales tax, and 0.5% country tax

6.5% + 0.5% = 7%

Multiply the total amount spent by the total tax

Remembering that you need to convert the 7% into an integer, by simply diving by 100 first

135.35 * 0.07 = 9.47

son4ous [18]

Answer:

The statement is true about whether A and B are independent eventa is fourth option:

A and B are not independent events because P(A/B)=0.375 and P(A)=0.25

Step-by-step explanation:

Let A be the event that the person rides the bus to school, then:

P(A)=75/300

P(A)=0.25

Let B be the event that the person has 3 or more siblings, then:

P(B)=24/300

P(B)=0.25


P(A/B)=9/24

P(A/B)=0.375


Like P(A/B)=0.375 is different to P(A)=0.25 the events are not independent


Answer. Fourth option:

A and B are not independent events because P(A/B)=0.375 and P(A)=0.25

3. Jen’s parents buy a tablet for her to use in school. Of the $1500 cost, her parents expect her to pay back $1000 one year lat
NNADVOKAT [17]

Answer:

<h3>33.3%</h3>

Step-by-step explanation:

Using the formula for calculating simple interest as shown;

Simple Interest = Principal * Rate *Time/100

Principal = Cost of tablet = $1500

Interest after one year  =  $1500-$1000 = $500

Time = 1year

Substituting this values into the formula;

500 = 1500*rate*1/100\\Cross\ multiplying\\50,000 = 1500 * rate\\Rate = 50,000/1500\\Rate = 33.3%

The interest rate that her parents assumed is 33.3%

Artist 52 [7]

Answer:

\boxed{GJ = 76 \ degrees}

Step-by-step explanation:

According to Angles of intersecting chords theorem:

∠GAJ = \frac{1}{2} (BD+GJ)

Where ∠GAJ = 50 , BD = 24 and GJ = ?

50 = \frac{1}{2} (24+GJ)

Multiplying both sides by 2

100 = 24 + GJ

GJ = 100-24

GJ = 76 degrees
