Answer:

(- 1, 0)

Step-by-step explanation:

The x- intercept is where the function crosses the x- axis.

The y- coordinate of any point on the x- axis is zero, hence

The point (- 1, 0 ) is the x- intercept

Advocard [28]

I answered part b first before a, bec6 the answer to part b is what would aid me in answering part a

Answer:

B. The t test statistic is the appropriate test.

A. Reject the null hypothesis

Step-by-step explanation:

X1 = 6.841, sd1 = 0.155, n1 = 15

X2 = 6.701, sd2 = 0.108, n2 = 10

1. The appropriate test statistic for this question is the t test.

T = x1-x2/√sd1²/n1 + sd2²/n2

T = 6.841-6.701/√0.155²/15 + 0.108²/10

= 2.66

H0: u1 = u2

H1; u1>u2

Significance level = 0.05

Df = n1+n2-2

= 15+10-2

= 23

T critical = 1.714

2.66>1.714

So we have to reject the null hypothesis. Since we have enough evidence that supports this claim that fruit flavor bubble gum is on average, thicker than the fruit flavored gum.

kvasek [131]

Answer

1.) B

2.)  3 hours

Step-by-step explanation:

1.)  option B is correct I think because it shows he will either be equal to or less than how much money he wants to spend

2.) i got three because if you sent up the equal I picked in question one then you subtract 28 from 250 giving u 222 and you divide that by 65 giving you 3.4 but he only charges by the whole hour so that .4 of an hour he wouldn't charge you for

Find the length of AC.
xeze [42]

Answer:

D. 8 cm

Step-by-step explanation:

Reference angle = 60°

Opposite side = BC = 8√3

Adjacent side = AC = ?

Thus:

Tan (60) = opp/adj

Tan (60) = (8√3)/AC

AC*Tan(60) = 8√3

Divide both sides by tan (60)

AC = (8√3)/Tan(60)

AC = (8√3)/√3 (tan 60 = √3)

AC = 8 cm
