3. Laura walks 3/5 mile to school each day. Isaiah walk to school is 3 times as long as Laura's. Howfar does Isaiah walk to scho

Finger [1]

Lets write down what we know...

Laura walks 3/5 mile to school everyday

Laura=3/5mile

Isaiah's walk is 3 times as long as Lauras, so

Isaiah=Laura*3

We know how far Lauras walk is so we can solve for Isaiah's walk

Isaiah=3/5*3 (or Isaiah=3/5+3/5+3/5 if thats easier for you to solve for)
Isaiah=9/5 miles

Now we know the answer! Great, Isaiah walks 9/5 miles to school each day. But 9/5 is an improper fraction, so lets convert it to a mixed number.

9/5=

To solve for this, we have to find out how many times 5 can go into 9. 5 goes into 9 one time with a remainder of 4, so we can write the mixed number as.

9/5= 1 4/5

Isaiah walks 9/5miles or 1 4/5 miles. Both are correct.

The sides of a hexagon are 2, 3, 2, 4, 7, and 6. Find the perimeter of a similar hexagon with two sides of length 3.

Basile [38]

The first hexagon: 2, 2, 3, 4, 6, 7

The second hexagon: 3, 3, a, b, c, d

The hexagons are similar. Therefore the sides are in proportion.

$\dfrac{a}{3}=\dfrac{3}{2}$ <em>multiply both sides by 3</em>

$a=\dfrac{3}{2}=4.5$

$\dfrac{b}{4}=\dfrac{3}{2}$ <em>multiply both sides by 4</em>

$b=\dfrac{3}{2}\cdot4=6$

$\dfrac{c}{6}=\dfrac{3}{2}$ <em>multiply both sides by 6</em>

$c=\dfrac{3}{2}\cdot6=9$

$\dfrac{d}{7}=\dfrac{3}{2}$ <em>multiply both sides by 7</em>

$d=\dfrac{21}{2}=10.5$

The perimeter:

$P=4.5+6+9+10.5=30$

The blood pressure in millimeters was measured for a large sample of people. The average pressure is 140 mm, and the SD of the m

Amanda [17]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Assum a normal distribution :

Mean (m) = 140 mm

Standard deviation (sd) = 20 mm

The percentage of people with blood pressure between 115 and 165 mm.

Zscore = (x - m) / sd

X = 115 mm

(115 - 140) / 20

-25/20 = - 0.625 = - 0.63

P(z<-0.63) = 0.2643

X = 165 mm

(165 - 140) / 20

25/20 = 0.625 = 0.63

P(z< 0.63) = 0.7357

0.7357 - 0.2643 = 0.4714 = 47.14%

B.) The percentage of people with blood pressure between 140 and 165 mm.

Zscore = (x - m) / sd

X = 140 mm

(140 - 140) / 20

0/20 = 0 = 0

P(z<0) = 0.5000

X = 165 mm

(165 - 140) / 20

25/20 = 0.625 = 0.63

P(z< 0.63) = 0.7357

0.7357 - 0.5000 = 0.2357 = 23.57%

C.) ___ The percentage of people with blood pressure over 165 mm.

X = 165mm

(165 - 140) / 20

25/20 = 0.625 = 0.63

1 - P(z< 0.63) = 0.7357

1 - 0.7357 = 0.2643 * 100% = 26.43%
