Answer:

<u>Step-by-step explanation:</u>

area of rectangle = length × breadth

area of rectangle = 4 × 2

area of rectangle = 8m²

area of Triangle = 1/2 × base × height

area of Triangle = 1/2 × 4 × 3

area of Triangle = 6m²

Total area = 8 + 6

Total area = 14m²

A jar of peanut butter contains 454 g with a standard deviation of 10.2 g. Find the probability that a jar contains more than 46

Fofino [41]

Answer:

The probability that a jar contains more than 466 g is 0.119.

Step-by-step explanation:

We are given that a jar of peanut butter contains a mean of 454 g with a standard deviation of 10.2 g.

Let X = <u><em>Amount of peanut butter in a jar</em></u>

The z-score probability distribution for the normal distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = population mean = 454 g

$\sigma$ = standard deviation = 10.2 g

So, X ~ Normal( $\mu=454 , \sigma^{2} = 10.2^{2}$ )

Now, the probability that a jar contains more than 466 g is given by = P(X > 466 g)

P(X > 466 g) = P( $\frac{X-\mu}{\sigma}$ > $\frac{466-454}{10.2}$ ) = P(Z > 1.18) = 1 - P(Z $\leq$ 1.18)

= 1 - 0.881 = <u>0.119</u>

The above probability is calculated by looking at the value of x = 1.18 in the z table which has an area of 0.881.

What is the area of a sector with a central angle of 3pi/5 radians and a diameter of 21.2cm

Elenna [48]

Answer: 105.84 cm^2

To find the answer, first you have to start by finding the percent of the circle in the sector. Convert the radians given to 108 degrees. 108 out of 360 is 30%.

Now, find the area of the circle. It's pi x r^2, so the area is 352.810.

Multiply this by 30% to find our area of 105.84 cm^2

10. A bag contains 4 red balls, 6 green balls and some white balls. If the probability of not drawing a white ball in one draw b

klasskru [66]

Answer:

No of white balls = 5

Step-by-step explanation:

Given that,

Total no of red balls = 4

Total no of green balls = 6

The probability of not drawing a white ball in one draw be, $P=\dfrac{2}{3}$

We need to find the number of white balls. Let there are x balls.

The probability of drawing a white ball = 1 - the probability of not drawing a white ball

= 1 -2/3

= 1/3

Using the formula for solving probability of having a white ball.

$P=\dfrac{\text{favorable outcome}}{\text{total no of outcomes}}\\\\\dfrac{1}{3}=\dfrac{x}{4+6+x}\\\\\dfrac{1}{3}=\dfrac{x}{10+x}\\\\10+x=3x\\\\10=2x\\\\x=5$

Hence, there are 5 white balls.

A clothing designer had 173.4 meters of fabric to make identical sweaters, of all the same size. If each sweater used 3 meters o

s344n2d4d5 [400]

57 sweaters can be made from 173.4 meters of fabric

Step-by-step explanation:

Given,

Total fabric available = 173.4 meters

Fabric used for one sweater = 3 meters

Let,

x be the number of sweaters.

Fabric used for one sweater * Number of sweaters ≤ Total fabric available

$3x\leq 173.4$

Dividing both sides by 3

$\frac{3x}{3}\leq \frac{173.4}{3}\\x\leq 57.8$

57 sweaters can be made from 173.4 meters of fabric
