Answer:

Step-by-step explanation:

1. Define word "zeros"

zeros = x-intercepts

2. Find x-intercepts

(-2, 0) and (-4, 0)

x-intercepts = -2, -4 or -4, -2

Answer:

C) (-4,-2)

Step-by-step explanation:

The zeroes is where the function passes through 0, and in this graph it passes through (0,-4) and (0,-2)

∠A and \angle B∠B are complementary angles. If m\angle A=(x+16)^{\circ}∠A=(x+16) ∘ and m\angle B=(x-12)^{\circ}∠B=(x−12) ∘ , the

Elena-2011 [213]

Answer:

Step-by-step explanation:

∠A + ∠B = 90 {∠A & ∠B are complementary}

x + 16 + x - 12 = 90

x + x + 16 - 12 = 90 {Combine like terms}

2x + 4 = 90 { Subtract 4 form both sides}

2x = 90 - 4

2x = 86 {divide both sides by 2

x = 86/2

x = 43

C. Find the value of X. Show your work. Congruent triangles

Dmitriy789 [7]

Answer:

Step-by-step explanation:

1) 97 + x = 64 + 27 {Exterior angle property}

97 + x = 91

x = 91 - 97

x = -6

2) 4x + 17 + 80 + x + 23 = 180 {Angle sum property of triangle}

4x + x + 17 +80 + 23 = 180

5x + 140 = 180

5x = 180 - 140

5x = 40

x = 40/5

x = 8

Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units ass

In-s [12.5K]

Answer:

is an attachment

test statistic = 9.87

p value is less than 0.01

Not all means of the three assembly methods are equal

Step-by-step explanation:

the anova table is an attachment

total number of methods = k = 3

number of observations n = 30

for treatment, df = 3-1 = 2

for error, df = 30 -3 (n-k) = 27

sst = 10800, sstr = 4560, sse = 10800-4560 = 6240

we find the mean of squares for error

sse/df of error = 6240/27 = 231.11

mean of squares for treatment = 4560/2 = 2280

test stat

F = 2280/231.11

= 9.8654

using f distribution table;

alpha = 0.05

df = 2 , 27

we get 3.35

h0; no difference in mean

h1; there is difference

9.87 > 3.35 so we reject H0, there is difference in means. all are not equal.

pvalue calculation

using excel,

FDIST(9.8654, 2, 27) = 0.0006078

p value is less than 0.01

we conclude that a. Not all means of the three assembly methods are equal
