The speed of Issam is 4 2/5 km/hr

<h3>Rate of change</h3>

The speed of Issam is as known as the rate of change. The formula for calculating speed is expressed as;

Speed = Distance/Time

Given the following parameters

distance = 6 3/5km

Time = 1 1/2 hour

Substitute the given parameters

Speed = (6 3/5)/(1 1/2)

Speed  = (33/5)/(3/2)

Speed = 33/5 * 2/3

Speed = 22/5

Speed = 4 2/5 km/hr

Hence the speed of Issam is 4 2/5 km/hr

Suppose the scores on a test given to all juniors in a school district are normally distributed with a mean of 74 and a standard
ivann1987 [24]

Answer:

\mu -\sigma = 66 , \mu +\sigma = 82

\mu -2\sigma = 58 , \mu +2\sigma = 90

\mu -3\sigma = 50 , \mu +3\sigma = 98

And in the figure attached we see the limits with the percentages associated.

Step-by-step explanation:

For this case we know that the random variable of interest is the scores on a test given to all juniors in a school district follows a normal distribution with the following parameters:

X \sim N(\mu= 74, \sigma =8)

For this case we know from the empirical rule that within one deviation from the mean we have approximately 68.2% of the data, within 2 deviations from the mean we have 95% and within 3 deviation 99.7%

We can find the limits and we got:

\mu -\sigma = 66 , \mu +\sigma = 82

\mu -2\sigma = 58 , \mu +2\sigma = 90

\mu -3\sigma = 50 , \mu +3\sigma = 98

And in the figure attached we see the limits with the percentages associated.

Karen, 28 years old and a single taxpayer, has a salary of $33,000 and rental income of $33,000 for the 2019 calendar tax year.
mart [117]

Answer:

$4,800

Step-by-step explanation:

The maximum contribution for traditional IRA in 2019 = $6000

Given that;

karen has a salary of $33,000 and rental income of $33,000; then total income = $66,000

AGI phase-out range for traditional IRA contributions for a single taxpayer who is an active plan participant is $64,000 – $74,000.

PhaseOut can be calculated as: \frac{66,000-64000}{74,000-64,000} *6000

= \frac{2000}{10000} *6000

= 0.2 * 6000

= 1200

Therefore, the  maximum amount that Karen may deduct for contributions to her traditional IRA for 2019 = The maximum contribution for traditional IRA in 2019 - PhaseOut

= $6000 - $1,200

= $4,800

27) Harry made 4 hits in 9 times at-bat. If she keeps the same success level, how many hits should she make in 18 times at bat?
9966 [12]

Answer:

<u>8 hits</u>

Step-by-step explanation:

The ratio is :

  • hits : times-at-bat = 4 : 9

Now, we have 18 times at bat.

Multiply both sides of the ratio with 2 :

  • 4 x 2 hits : 9 x 2 times at bat
  • <u>8 hits</u> : 18 times at bat

Harry should make <u>8 hits</u> in 18 times at bat.
