Answer:

Wanda brought 9 carrot sticks.

Step-by-step explanation:

  1. Convert 30% to a decimal by removing the percent sign and dividing by 100: 30 ÷ 100 = 0.30
  2. Substitute 0.30 for 30% in the equation: 30% x 30 = Y becomes 0.30 * 30 = Y
  3. Do the math: 0.30 x 30 = 9
  4. Y = 9
  5. So 30% of 30 is 9
  6. Double check your answer with the original question: How many carrot sticks did Wanda bring? Multiply 0.30 x 30 = 9

Evaluate the given expression. Subscript 5 Baseline P Subscript 2 a. 40 c. 25 b. 32 d. 20
Leto [7]

Answer:

d. 20

Step-by-step explanation:

The given question implies 5 permutation 2, i.e _{5}P_{2}.

But,

_{n}P_{r} = \frac{n!}{(n - r)!}

So that for _{5}P_{2}, n = 5 and r = 2.

_{5}P_{2} = \frac{5!}{(5 - 2)!}

     = \frac{5!}{3!}

    = \frac{5*4*3*2!}{3*2!}

Cancel out 3 and 2 with respect to the numerator and denominator.

_{5}P_{2} = 5 * 4

     = 20

Therefore,

_{5}P_{2} = 20

So that the correct option is D.

Answer:

rework the equation

y - 1 = 0.2x - 0.4

y = 0.2x - 0.4 + 1

y = 0.2x + 0.6

0.6 is the intercept

to find x

0= 0.2x + 0.6

-0.6 = 0.2x

x = -3

According to a Field Poll conducted February 8 – 17, 2005, 79% of California adults (actual results are 400 out of 506 surveyed)
Jobisdone [24]

Answer: (0.760, 0.820)

Step-by-step explanation:

Let p be the population proportion of all adults feel that "education and our schools" is one of the top issues facing California.

Given : 79% (actual results are 400 out of 506 surveyed) of California adults feel that "education and our schools" is one of the top issues facing California.

i.e.Sample size : n= 506

Sample proportion : \hat{p}=0.79

Critical value for 90% confidence interval ( Using z-value table) :

z=1.645

Now, the 90% confidence interval for the population proportion will be :

\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

i.e. 0.79\pm (1.645)\sqrt{\dfrac{0.79(1-0.79)}{506}}

i.e. 0.79\pm (1.645)(0.0181)

\approx0.79\pm 0.030=(0.79-0.030,\ 0.79+0.030)\\\\=(0.760,\ 0.820)

Hence, the 90% confidence interval for the population proportion= (0.760, 0.820)
