7.76 to one decimal place

= 7.8

We are looking at one decimal place, in this case the number 7 after the decimal place next to 6. Any number above 5 rounds up the number in front of it. 6 is above 5 so it changes the 7 to an 8.

Shari takes violin lessons. The equation

Arlecino [84]

Answer:

if $-192$ is not divided by $-4$ , then y - intercept becomes $-192$ .

In such a situation, Shari thought that -192 was the y-intercept.

Step-by-step explanation:

Given: $288x-4y=-192$

Solution:

Consider the equation:

$288x-4y=-192$

To find y-intercept, put $x=0$

$288(0)-4y=-192\\-4y=-192\\y=\frac{-192}{-4}\\y=48$

In the second step $-4y=-192$ ,

if $-192$ is not divided by $-4$ , then y - intercept becomes $-192$ .

In such a situation, Shari thought that -192 was the y-intercept.

Based on an online poll, 35% of motorists routinely use their cell phone while driving. Tree people are chosen at random from a

mart [117]

Answer:

The anwerss to the question are

(A) P(No less than two people use their phones while driving) = 0.1225

(B) P(The probability that no more than one person of the three people use their cell phone while driving) = 0.147875

Step-by-step explanation:

The given relations are

Percentage of motorists that routinely drive while sing their phone = 35 %

The probaboloty that if a peerson is random;ty selected from a group of hudred person routinely uses their phone wjile friving P(phone) = 35

The probability that a motorist randomly selected fron a set of 100 do not routinely use thir phones while driving = P(No celll phone) = 65

Then the probability that when three people are selected at random at least two people of the three people use their cell phone while driving is

P(phone) = 35/100m = 0.35

P(No celll phone) = 65/100 = 0.65

(A) Probability of at least two of three use their phones whle driving is

0.35×0.35×0.65 +0.35×0.35×0.35 = 0.1225

(B) The probability of only one person out of three seted use their phones while driving is

(0.35)(0.65)(0.65) = 0.147875

A regular-size box of cereal measures 3 1/2 inches by 8 1/2 inches by 15 inches. The manufacturer also sells an individual-size

Phoenix [80]

The individual-size box of cereal is a rectangular prism with a volume of 44.625 inches³.

<h3>What is the volume of a rectangular prism?</h3>

The volume of rectangular prism of length l, width w and height h is given by:

V = lwh.

In this problem, the standard dimensions are:

l = 3(1/2) = 3 + 0.5 = 3.5 inches.

w = 8(1/2) = 8 + 0.5 = 8.5 inches.

h = 15 inches.

The individual-size box has a 1/10 of the volume of the original box, hence:

V = 0.1 x 3.5 x 8.5 x 15 = 44.625 inches³.

A Canadian longitudinal study1 examined whether giving antibiotics in infancy increases the likelihood that the child will be ov

dalvyx [7]

Answer:

1. $H_{0}$ : p = 0.70 , $H_{a}$ : p > 0.70

2. Test Statistic : 0.54 , P value : 0.2946

3. Fail to reject null Hypothesis

4. No.

Step-by-step explanation:

1. Null hypothesis is 70% of children receive antibiotics.

Alternative hypothesis is more than 70% of children receive antibiotics.

2. Test statistic is calculated as;

z = $\frac{p (1 - p)}{\sqrt{\frac{p (1-p}{n} )} }$

z = $\frac{0.01}{0.0185}$

z = 0.54

3. p value is calculated as;

1 - right tailed probability

1 - 0.7054 = 0.2946
