A recipe that makes eight Jamberma muffins calls for 1 1/2 teaspoons of baking powder how much baking powder is needed to make t

dimulka [17.4K]

8/ (1 1/2) = 36/x....8 muffins to 1 1/2 tsp = 36 ( 3 doz) muffins to x tsp
this is a proportion, so we cross multiply
(8)(x) = (1 1/2)(36)
8x = 3/2 * 36
8x = 108/2
8x = 54
x = 54/8
x = 6 3/4 <=== 6 3/4 tsps are needed to make 3 doz muffins

Can you show me this step by step please

Leya [2.2K]

Answer:

clockwise from left, the missing side lengths are 8 m, 13 m, 8 m

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of its sides. Sides with the same hash mark have the same length, so the perimeter (in meters) is ...

38 = (3x+1) +(2x) +(9) +(2x)

38 = 7x +10

28 = 7x . . . . . . subtract 10

4 = x . . . . . . . . divide by 7

Then the short sides are ...

2x = 2·4 = 8 . . . meters

and the long side is ...

3x+1 = 3·4 +1 = 13 . . . meters

In a random sample of 600 cars making a right turn at a certain intersection, 157 pulled into the wrong lane. Test the hypothesi

nevsk [136]

Answer:

The statistic value |Z| = 2.053 > 1.96 at 0.05 Level of significance

Null hypothesis is rejected

Alternative hypothesis is Accepted

Actually 30% of all drivers make not this mistake at the given intersection

b)

The test statistic value |Z| = 2.053 >2.576 at 0.01 Level of significance

Null hypothesis is Accepted

Actually 30% of all drivers make this mistake at the given intersection

Step-by-step explanation:

Step(i):-

Given Population proportion = 30% or 0.30

Given data In a random sample of 600 cars making a right turn at a certain intersection, 157 pulled into the wrong lane

sample proportion

$p^{-} = \frac{x}{n} = \frac{157}{600} = 0.2616$

Null hypothesis:- H₀: p = 0.30

Alternative hypothesis : H₁:p≠0.30

Step(ii):-

Test statistic

$Z = \frac{p^{-}-P }{\sqrt{\frac{p(1-p)}{n} } }$

$Z = \frac{0.2616-0.30 }{\sqrt{\frac{0.30(1-0.30)}{600} } }$

Z = -2.053

|Z| = |-2.053| = 2.053

Level of significance = 0.05

Z₀.₀₅ = 1.96

The calculated value |Z| = 2.053 > 1.96 at 0.05 Level of significance

Null hypothesis is rejected

Alternative hypothesis is Accepted

Conclusion:-

Actually 30% of all drivers make not this mistake at the given intersection

b)

Given level of significance = 0.01

Z₀.₀₁ = 2.576

The calculated value |Z| = 2.053 >2.576 at 0.01 Level of significance

Null hypothesis is Accepted

Actually 30% of all drivers make this mistake at the given intersection
