Answer:

2b( 12 - 17a)

Step-by-step explanation:

This is the answer because:

1) Fator 2b out of 24b - 34ab:

2b x 12 = 24b = 24b ÷ 2b = 12

2b x 17a = 34ab = 34ab ÷ 2b = 17a

Therefore, the answer is 2b( 12 - 17a).

Hope this helps! :D

If M is in the interior of ∠RTD, m∠RTM = 40°, and m∠RTD = 65°, then m∠MTD = .
ASHA 777 [7]

Answer:

MTD = 75

Step-by-step explanation:

RTD + RTM + MTD = 180

     65 + 40 + MTD = 180

            105 + MTD = 180

Subtract 105 from both sides.

                      MTD = 75

Don't forget to mark me brainliest : )

The producer of a certain bottling equipment claims that the variance of all its filled bottles is .027 or less. A sample of 30
Darya [45]

Answer:

The p-value for the test is 0.0459.

Explanation:

The question involves a chi-squared test whose p-value is to be determined.

H₀: σ² ≤ 0.027   (null hypothesis)

H₁: σ² > 0.027    (alternative hypothesis)

Standard deviation = s = 0.2

Hence, s² = (0.2)² = 0.04

Sample size = n = 30

Degree of freedom = n - 1 = 30 - 1 = 29

Significance level = 0.05

Test statistic: X² = (n - 1)s² / σ²

                           = (30 - 1) x 0.04 / 0.027

                           = 42.9629

The p-value can now be determined using the Excel function:

CHISQ.DIST.RT(42.9629,29)  = 0.0459

Hence, the p-value for the test is 0.0459.

il63 [147K]

9514 1404 393

Answer:

  • $10,000 at 5%
  • $22,000 at 6%

Step-by-step explanation:

Let x represent the amount invested at 6%. Then 32000-x is the amount invested at 5%, and the total interest earned is ...

  0.06x +0.05(32000 -x) = 1820

  0.01x +1600 = 1820 . . . . simplify

  0.01x = 220 . . . . . . . . . .  subtract 1600

  x = 22,000 . . . . . . . . . . . multiply by 100

  32000 -x = 10,000

Phyllis invested $22,000 at 6% and $10,000 at 5%.
