Answer:

23%<x<43%

Step-by-step explanation:

The formula for calculating confidence interval is expressed;

Confidence Interval = p ± z√p(1-p)/n

n is the sample size

z is the z score at 98% confidence interval

n is the sample size = 120

z =  2.33

If in a randomly chosen handful of 120 beans 40 were black, then;

p = 40/120

p = 4/12

p = 0.33

CI = 0.33± 2.33√0.33(1-0.33)/120

CI = 0.33± [2.33√0.33(0.67)/120]

CI =  0.33± [2.33√0.2211/120]

CI = 0.33± [2.33(0.04292)]

CI = 0.33±0.100014

CI = (0.33-0.100014, 0.33+0.100014)

CI = (0.229, 0.430014)

CI = (22.9, 43.0014)

Hence 98% confidence interval for the proportion of black beans in the jar is 23%<x<43%.

Explanation:

n = number of sides = 5

S = sum of the interior angles of a convex polygon with n sides

S = 180(n-2)

S = 180(5-2)

S = 180*3

S = 540

6 is the number i think that

-1 is  the number that if subtracted from 7 and 12, the product of the two numbers gives 104

Two or more expressions with an Equal sign is called as Equation.

Given,

We need to find the number that if subtracted from 7 and 12, the product of the two numbers gives 104

We need to find two integer factors of the number 104 that multiply up 104 and differ by 12-7 = 5 units

104=2×52

104=4×26

104=8×13

If we consider the  unknown number as (-1) then

number that if subtracted from 7  

7-(-1)=8

number that if subtracted from 12

12-(-1))=13

8×13=104

Hence -1 is the number that if subtracted from 7 and 12, the product of the two numbers gives 104.

Answer:

B. Transitive property

Step-by-step explanation:

Transitive property, just like in the case of transitive property of equality, which says that if m = n, and o = m, therefore, o = n.

This property is what is also applied in the given proof above.

Thus:

Since, <1 ≅ <5, and <3 ≅ <5, therefore,

<3 ≅ <5 by transitive property.

The answer is:

Step-by-step explanation:

you turn them to a decimal to make them easier and then divide them to get the answer.

Answer: B) Demand will most likely be elastic

Place yourself in the shoes of the employer. To them, demand is them needing/wanting workers. Specifically we call this "labor demand". The supply is the potential or current worker providing the service and/or making the product.

If the price goes up, then this means the worker earns higher wages. This in turn causes labor demand to fall. So the employer will be less likely to hire more workers if the wages increase. It's similar to how if the price of an item goes up in a store, then less people are probably going to buy it.

Demand is elastic because a small change in price causes a large change in demand. The company is going to be sensitive to wage changes. The company sees that it is approaching the diminishing returns, so it is likely to scale back on labor to save costs. It's all about trying to minimize costs and maximize revenue. Often, revenues can't be changed very much since customers are themselves sensitive to price changes (assuming there are substitutes in the market), so the company will turn to trying to reduce costs as much as possible leading to maximum profit.

Answer:

P=37,68

Step-by-step explanation:

Those are 4 semi-circles, so basically 2 circles

The diameter of the circles d=6

[tex]p =2 \times d \times \pi[/tex]

[tex]p = 2 \times 6 \times 3.14[/tex]

P=37,68

Answer:

Step-by-step explanation:

perimeter of semicircle = 1/2 π d

                                       = 1/2 π (6)

                                       = 9.425 x 4 semicircles

Answer:

8 weeks

Step-by-step explanation:

Given

[tex]Initial\ Height = 8cm[/tex]

[tex]Growth = 2cm[/tex] weekly

Required

Determine the duration it gets to 24 weeks

First, we need to represent the scenario as a function.

Let the number of weeks be w.

So:

f(w) = Initial Height + Growth * Number of Weeks

This gives:

[tex]f(w) = 8 + 2 * w[/tex]

[tex]f(w) = 8 + 2w[/tex]

When the duration is 24 weeks,

We have that:

[tex]f(w) = 24[/tex]

Substitute 24 for f(w)

[tex]24 = 8 + 2w[/tex]

Make 2w the subject of formula

[tex]2w = 24 - 8[/tex]

[tex]2w = 16[/tex]

Make w the subject of formula

[tex]w = 16/2[/tex]

[tex]w = 8[/tex]

Hence, it'll take the plant 8 weeks to get to 24cm

Answer:

Step-by-step explanation:

It's a proportion rather than an equation that you might be more accustomed to.

2/0.05 = x/ 0.95       Cross multiply

2 * 0.95 = x * 0.05    Divide by 0.05

2 * 0.95/0.05 = x

x = 38 grams of sugar should be added to the 2 grams of cinnamon.

There's another way to do it.

2/0.05 = (x + 2)/1      Cross multiply

2*1 = 0.05x + 0.1       Subtract 0.1 from both sides

1.9 = 0.05x

1.9/0.05 = x

x = 38

Which ever way you understand better is the answer. 100 / 100% is 1
